First Parks on the Air Activation


I know I'm working on getting up big antennas and more power, but that doesn't mean I don't want to go out portable.

Years ago I was active a bit in Summits on the Air (SOTA) and was even the Georgia regional manager for SOTA for a short while.  I stopped having as much time for SOTA as I'd like, and there really aren't many SOTA peaks near me, so my SOTA participation dropped to zero.  About the same time, Parks on the Air (POTA) got going.  I never did anything with it, only occasionally giving out a random QSO every once in a while to an activator.

Within the past couple weeks, I've actually started looking at POTA a little more closely, and started actually going after some activators that were spotted at POTA.app.  Then a few nights ago I saw my little-used KX3 over in the corner and decided I'd do my first POTA activation this weekend.

K-2207 QSOs
I kinda went off half-cocked, just tossing a bunch of stuff in a bag Saturday morning and heading off to the nearest park, about a half-hour away.  When I got there and started putting stuff together, I realized I wasn't as well-prepared as I'd like to be!  My throw bag was missing, as was a spool of mini paracord I use for hanging antennas.  So, my antenna installation wasn't as robust as I'd like.

I started with a random-wire, hung vertically with a counterpoise.  This had always worked great on SOTA peaks, but those were better locations on tops of mountains.  A low random wire in the flatlands wasn't nearly as good an antenna.  Plus, I couldn't find my binding post / BNC adapter and used a 4:1 balun.  Let's say the tuner in the KX3 struggled.  I struggled too. 


After a half- hour, I only had 5 cw contacts in the log and decided I needed to find some SSB chasers - both for park-to-park (P2P) credit, and just to get the 10 contacts I needed for a valid activation.  I found 5 SSB contacts in 15 minutes, and went back to CW for a few more before calling it a day from my first park:  Watson Mill Bridge State Park, K-2207.

K-2205 QSOs
So I packed it all up and drove to my second park of the day, Victoria Bryant State Park, K-2205, about a 20 or 30 minute drive.  Here I decided to use a Par End Fedz antenna.  I got it hung a bit better, and after about 40 minutes, I had 18 CW contacts in the log.  It was starting to spit rain, so I bagged it and headed home.

I had plans for another two parks, but my general lack of preparation and the weather looking like it was turning south, I headed back to the house.  I'm re-grouping, and next time will be much better prepared, with a better, more well thought out game plan.  

POTA is a lot more accessible than SOTA for most people.  There are simply more POTA sites available to the average ham.  POTA activations can happen from the vehicle, while SOTA requires a certain amount of human propulsion.  Because of that, multiple activations are easier to do in a single day.  And, there is simply a lot more activity on POTA than SOTA.  POTA is also easier in inclement WX.

Maybe next spring I can combine a POTA and SOTA activity.  Keep checking the spots.

QRP no more?

Lonnnng time, no post!

Big changes are coming to AA4GA - the biggest of which is doing less QRP with small antennas, and going back to QRO with bigger antennas.  

I spent a full solar cycle operating at 5 Watts or less, and had a ton of fun.  Did fairly well in a few contests, and worked over 200 DXCC countries.  All with little wire antennas:  verticals and doublets mostly.  Not very high, usually around 40' or so.

But, my biggest complaint about wire antennas is that they're just too hard to keep up.  Even something like a simple inverted-L threaded through the branches won't stay up long.  The last one I put up for 160 only stayed up for about four months.  

I needed a more permanent antenna installation, and decided to put back up my Rohn 55G that I've had stored for about 15 years.  As of now, it looks like I'm going to end up with a tower height of 75' with a JK Mid-Tri-40 at the top.  The tower will probably be involved in 80m and 160m antennas too, so hopefully I won't sit down to operate a contest and discover that my antennas are all on the ground.  We'll see.

And, since I'm going to have (relatively) big antennas again, I figured it was time to go up to legal output, so I've added an Alpha 8410 to the mix.  Right now, just driving with 12 Watts from the K3/10, I'm getting around 500-ish watts out, but once I hit it with more drive, I'll be able to get the full 1500W out.

The new antenna location is also much better sited than the wires I've used.  I'm probably getting over 10 dB just by moving where on the property the antennas are located according to HFTA.  That, a gain antenna, and the amplifier means my signal will be going up by, oh, 35 to 40 dB compared to 5 Watts and a wire.  A noticeable change I'd say!

NoGAQRP KX3/PX3 Stand

I'm a member of the North Georgia QRP Club - a loosely organized group based roughly out of Atlanta, GA. I've had more enjoyment being a member of this club than any other in my 40 years as a ham. Part of that is due to the wide variety of talents shown by the various members. We've got members who have won the FDIM home-brew competition, at least two past presidents of QRPARCI, some good contesters and DXers, some fine programmers, superb CW ops, and even a few woodworkers in the group. The meetings generally detail some activities from each of these groups, all of which are impressive.

Original side-by-side stand
One of the woodworkers is Paul Kelley, W4KLY. In addition to other woodworking projects, Paul has built a number of nice operating desks for Atlanta area hams. Another radio-related line he produces are wooden stands to fit a variety of QRP rigs. His latest stand is a stand designed to hold both the KX3 and matching PX3 panadapter. Early in this project, I commissioned Paul to build a side-by-side stand for my KX3/PX3. Ever since I'd gotten the PX3, I was bothered by it and the KX3 not staying in exact alignment with each other...not a real big deal, but I wanted the two connected more solidly. In talking to Paul, I also ordered a slightly more angled stand to fit my desk/chair heights and where I was planning on using the KX3. The resulting stand was awesome - just exactly what I ordered - and I was a fairly happy customer. The biggest problem I had with the side-by-side stand is that it's difficult to access the headphone jack on the KX3. My plan was to build an external amplifier/speaker and just leave that connected to the KX3 full-time with a switch to choose speakers and/or headphones. All in all, not a bad problem.

160 Meter action in the "Big Stew" about 7am local
Well, at the last NoGAQRP meeting, Paul approached me with a new stand he wanted me to try.  He's gone through a lot of iterations trying to get his combo stand dialed it.  This stand places the PX3 above the KX3, which eliminates the problem of bad headphone access.   The KX3 is held at a shallower angle than my side-by-side stand, but because the stand is narrower,  I can keep the radio right next to my keyboard, where the shallower angle works.  I find this particularly comfortable during contests - the side-by-side stand requires a reach that isn't convenient during contests, or working split for that matter.

Nicely finished, including the NoGAQRP brand
Paul is known for his craftsmanship, and it shows in these stands.  He uses two thicknesses of Baltic Birch plywood, micro-nails, and uses a CNC router to ensure consistent results in cutting out what really is a complex shape.  The stands are branded with the mark of the North Georgia QRP Club, and several coats of clear lacquer are applied.  The stands are strong, but lightweight.  I've seen other stands for the KX3, both commercial and home-made, and in my opinion, none of them hold a candle to Paul's stands.  I recommend Paul's stands whole-heartedly.

As I mentioned, I'm a member of NoGAQRP, and Paul does donate a portion of the proceeds of each stand to NoGAQRP.  Also, in the interest of full disclosure, while I paid full price for my original stand, Paul did give me the latest version to try.  None of which detracts from the fact that these are truly nice stands.

You can order your own stand from NoGAQRP Club, just follow the links on this page for pricing and ordering information.  In addition to the over/under stand pictured here, Paul will entertain custom work as well, like he did for my original stand or you have an aftermarket heat-sink or other ideas.  If you have any questions at all, I'm sure Paul would be happy to address them, as he's quite passionate about these stands.  If you have any questions for me, just drop me an email via the addy listed on QRZ.

Cows Over the World


I absolutely love this!  This is how you should do a DXpedition.  Tom, KC0W is traveling across the Pacific, with no set-in-stone agenda:  “The determining factor will be when the pileups die down it’s time to pack everything up and move along,”  Read more about it here:  ARRL

Aven Circuit Board Holder

In May, at the North Georgia QRP group meeting's show & tell, Phil, K4PQC showed a circuit board holder he'd recently purchased off Amazon.  After he passed it around, a couple of us were inspired to order one - from our phones at the meeting!

Well, a couple nights ago I started to put a 80/30 kit into an Elecraft KX1, and decided it was time to try the circuit board holder, and I've got to say, I'm really glad I had it! It was especially helpful in holding the board vertical while I applied the solder sucker to clear some PCB holes, and also for threading on the two little sub-boards onto the main PCB. I can't imagine how frustrated I'd have been without this gadget or something similar.

Here's a photo of the holder in action with the KX1:

K8CR

Y'know...I really do need to post something positive here soon...but stuff like this shouldn't be passed up!

This is K8CR pretending to work VK0EK in the hopes that his call will end up in the DXpedition's log (which it apparently did) - he probably doesn't even have his volume turned up!


Friends, this is *not* the way to work DX! I had a boss one time tell me that no one is totally worthless, they can always serve as a bad example. Apparently K8CR has found his calling!

More Fun With Scammers

The scammers continue to try to steal my money...

I got an email overnight from JOHN P CHWALEK <johnk2iw@gmail.com> - or at least someone claiming to be John Chwalek - you may recall he's one of the ones who answered my WTB ad for a 2-NT and passed me along to a "friend" of his.

As it turns out, "John" has a Collins 75A4 that, for some reason, he thinks I might be interested in buying!

Here's the exchange:

<"JOHN">:  I have for sale  Collins 75A4 radio receiver. if still
interested let me know Thanks.
73;s

<ME>:  Nice radio!
I'd love to call you and talk about it....give me your phone number and I'll call later today.  In the meantime, could you send some photos?

Photo sent by "John"
<"JOHN">:  sorry am having hearing problem that is the reason am clearing up my shack.... here are some photos for your view
ASKING PRICE $955 + SHIPPING
73;s

<ME>:  How long have you had that radio....it looks to be in very good condition....did you have to replace the DSP module, or is the original OK?

<"JOHN">:  the radio is 14 months old and it still have the original DSP module..

<ME>:  Are you the original owner?

<"JOHN">:  i am the original owner


This was actually fun!  There are several things wrong here, that I suspect most of the readers have already figured out!  Additionally, the photo "John" sent is actually a photo from rigreference.com, from which that website's name was cropped out of the file.


And the kicker is that OM John Chwalek has been a Silent Key since 2012!  I don't think K2IW showed as an SK last week when I looked him up, but the QRZ record definitely reflects that now, so perhaps it was just recently brought to the attention of QRZ.   RIP K2IW.


And for the sake of folks looking to not get scammed, when I asked for the PayPal address to use, "John" said to use kaceyag@yahoo.com.  Hopefully it will get picked up by Google ...or you may want to send him some email yourself!


"Want to Buy" Scammers on QRZ, QTH, eHam, etc.

You may have read of my interaction with that less-than-honorable radio seller K1VVC while trying to buy a Drake 2-NT a few months back.  Well, after several more tries, I finally won an eBay auction on another 2-NT, but that deal fell through too...in a fishy manner.  Disgusted with eBay, I decided to post a "Want to Buy" ad looking for a 2-NT.  I posted on the Drake Yahoo group, QRZ, eHam, QTH.com, and maybe one or two I don't remember.  Apparently there are a lot of scumbags out there, as all these sites warn you to be careful buying and selling through their services.  QRZ even prohibits WTB ads for items worth more than $250 due to the rampant number of scammers.  But post a WTB, I did.  Warning - this may get a little convoluted....

Here's a timeline of the answers to my WTB ad.

12/10/15 - WTB ad placed.

12/11/15 - Received email from "Larry T. Williams <larrytwb4nadATgmail.com>" - this was my first response, and after an exchange of info and such, a deal was struck.  I had done a bit of looking around via Google and it appeared that "Larry" was legit.  He asked for payment via PayPal friends/family, and I said I'd send it as a purchase and add in an amount for the fees...to which he said no, just send friends and family.  This was a red flag, but stupidly, I chose to ignore it, and sent him 120 bucks via PayPal friends/family...still feeling uneasy.  Right after I sent the PayPal, I remembered Google's reverse image search, uploaded the 2-NT photo, and was rewarded with the info that the photo was from an eBay auction back in March of 2015 that didn't appear to involve "Larry" - plus the eBay description and the one "Larry" gave didn't quite jive.  So, less than 10 minutes after I sent "Larry" the money, I logged back into PayPal and discovered that "Larry" hadn't yet claimed the money, and I was able to cancel the transaction - that was close!  A little more digging revealed that someone had been using WB4NAD's identity to scam via the ham boards.  I sent "Larry" a message that something had happened with my PayPal account and the transaction didn't go through.  He made no offer of alternative payment methods.

12/11/15 - Received email from "Douglas P. Orr <douglaspw6tyATgmail.com>" - I told him I'd already made a deal on a 2-NT and would get back to him if it fell through.  I called the real W6TY and he assured me that the email wasn't from him - we had a nice brief chat - he's been off the air for a number of years.

12/18/15 - Received email from "Carl F. Groner <carlw2tzATgmail.com>" - hang on, this is where it starts to get confusing!  "Carl" sent an email that included a description that was a direct quote from a QRZ ad from 10/7/15 by K0JY stating “As you can see in the one photo it was putting out 80 watts on 40 meters.” Funny, there was no photo showing this. He said the price was $220.


Funny looking crystal!
Also funny was that he said “I have just used it very sparingly and on crystal control”. Funny because here is the 2-NT plainly sitting on top of an HG-10 VFO, and there is a wire coming out of the crystal socket!

Not the same transmitter!
In a later email, he mentioned that he had a 2-C as well and sent a photo of it and a 2-NT.  The photo of the 2-NT alone (with the HG-10 VFO) is from AB0CW's qsl.net page depicting a 2-B, 2-BQ, and 2-NT with an HG-10 VFO.  The photo of the 2-C/2-NT pair is from an eHam ad by VE3AZQ dated 5/11/10.

I asked the price of the 2-C and was told “price of the 2-NT is $112. i can sell both for $400, and it will be shipped to your doorstep.” - wow, that's about half the original asking price for the 2-NT!

1/2/16 - Received email from "John P. Chwalek <johnk2iwATgmail.com>" - the offer here was to sell me a 2-C.  The description was a direct quote of an ad by K0JY from 11/3/15.  This is the same RX K0JY had listed in his 10/7 ad.  And the photos are also from the K0JY ads.  

So, I mentioned to "John" that I was really just interested in a 2-NT, and he responded that he had a friend with one for sale: W2TY, whose email address was alanw2tyATgmail.com.  

1/2/16 - Received an email from "Aaron Aragon <aarounkj4vhsATgmail.com>" offering a 2-NT.  When asked for photos, he responded that he had a 2-C and a 2-NT, and sent the same photo from VE3AZQ that was sent earlier by "W2TZ".

1/2/16 - Received an email from "Alan J. Gottesman <alanw2tyATgmail.com>" offering a 2-NT.  This was the same description that "W2TZ" had given me earlier, and the photos were again from K0JY.

Whew!

So, I'm not sure if there are a lot of scammers out there or just one.  As you can tell, there is a lot of similarity in the email addresses.  They are all first name, followed by callsign and are gmail.com addresses - several also strangely include the middle initial.  Also, not plain in the descriptions above, but the language often just isn't "right".  Again, not 100%, but more often than one would expect, the emails close with "73's", not "73".  Once, maybe...but not as often as I saw it here.  In each and every case, PayPal was the only accepted form of payment - not even money orders, presumably because of the address discrepancy with QRZ and/or the ability to track down the scammers via a physical address.

Also, on QRZ.com, none of the scammer callsigns have email addresses associated with them.  With enough digging, you'll find that all of the scammer callsigns except K2IW have been used in scams.  [ETA: unfortunately, I just learned that VU2WAP was scammed out of $455 by someone pretending to be K2IW.  Ouch!]

Make no mistake about it, WB4NAD, W6TY, W2TZ, AB0CW, VE3AZQ, K2IW, W2TY, KJ4VHS, and W2TY are all victims here.  Their identities have been hi-jacked.  I have seen nothing that indicates any of these folks are scammers, and have either spoken with, corresponded with, or otherwise seen indications that they are victims here.

So the bottom line is - do be careful.  Do speak with the seller on the phone.  Do not use PayPal without buyer protection.  Do check to see if the seller has an email address on his QRZ page.  Etc.  I realize that this scammer(s) may get tipped off that his MO is pretty consistent and obvious.  If so, he may change his tactics a bit.  Just be very careful.

I got very lucky - I hope you don't get burned. 





CW Open 2015 QRP Teams

Ron, WB3AAL started forming QRP teams for this year's CW Open and tricked me, yes, tricked me into helping!  Not really, I've done this before, although this year was the most I've been able to be active in this contest.  And it's really a series of three four-hour contests all within one 24-hour period.  Sponsored by CW Ops, it's definitely a good one, with its own quirks...I just wish it wasn't on Labor Day weekend!

Anyway, we were able to put together two full 10-person teams.  Some of the team members were old hands at contesting, and for some, it was their first entry.  Because we're all QRP ops, we knew up front there was no chance of us winning the team competition, so it was all for pure fun and to show the QRO guys that we aren't afraid of jumping in on the action!

The teams were formed randomly with two exceptions.  One team was led by Ron and one by me, and the other exception was to ensure that the father/son duo of K1RID/KC1CMF were on different teams...to generate a little inter-family rivalry!

Here are the teams, along with their reported scores:

K1VVC - Caveat Emptor!

I'd like to talk about today's eBay interaction with Jon Weiner, K1VVC.  I can't really call it a transaction, as no funds or goods changed hands.  But they should have.

I've been looking for a Drake 2-NT off and on for a long while, more off than on...usually whenever I go to a hamfest.  But lately, I've started looking on eBay, and about three weeks ago, I saw a fair-looking 2-NT on eBay being offered by "radiotyke"...I had some questions about the rig, so I dropped him a note via the eBay messaging system, but never did get an answer.  I wasn't sure if I was being ignored, or if somehow my inquiry got missed.  In any event, I never did bid on the item without an answer to my questions and the radio sold for $156.03.

Now, I thought that was a little high for a 2-NT in that shape.  I remember them selling for $100-ish for a long time.  But inflation, scarcity, etc. seems to have driven the price up, and I've seen them selling on eBay the past few months for $102.50 up through $355...that doesn't count the one that went for 87 bucks - it was missing its covers.  I seem to recall seeing one for around $500 earlier in the year - which flabbergasted me!  To me, a fair price for a 2-NT in good shape these days would be in the $150-200 neighborhood.

This morning I got a notice from eBay for a new 2-NT listing.  Checking it out, I noticed it was the same seller as the one I saw three weeks ago.  I remembered not getting an answer on those inquiries, but I figured I'd try again.  I saw radiotyke had over 10k ratings contributing to a 99.5% feedback, so I figured he was pretty busy.  By the way, I worked for an eBay retailer for a couple years, and 99.5% is not considered a particularly good rating...but I've never had any problems dealing with anyone on eBay and have purchased from sellers with lower ratings, so I wasn't put off by that alone. I know that sometimes buyers leave negative feedback when they probably shouldn't, and sellers that are active tend to pick up the occasional negative feedback.

So, I decided I'd give radiotyke another try.  I cut and pasted the same questions I asked three weeks ago, and was answered pretty quickly.  Here's the total of our exchange via the eBay messaging system, with an occasional comment added by me:

05:22 [AA4GA] Is this transmitter operational? Has it been re-capped? Would you be interested in a Buy it Now transaction - I could pick up and you wouldn't have to bother with packing the rig (I live in GA)?

<I live less than two hours from K1VVC, and really would rather not subject the old radio to shipping, and wouldn't mind a little drive>

05:35 [K1VVC] Yes, the transmitter is working. I beleve it's completely unmodified. It's listed as for auction. If I added a "buy it now" price what would you offer?

05:51 [AA4GA] Say 175 including shipping? - which would be 175 net to you if I could pick up.

<right in the middle of my "fair price" range - the rig is pretty good cosmetically, not great, and will probably need new caps and maybe new tubes>

06:03 [K1VVC] Unfortunately eBay does not allow me to add a "buy it now" price after an item has a bid on it. If you're serious I can cancel the auction and relist it with a BIN of $175.

<at this point, we have a "meeting of the minds" and the deal has been made>

06:11 [AA4GA] You could list it for like 500 with a "make offer" option - that way I could make the 175 offer and you could accept - that would preclude someone jumping in and getting it for 175 that wasn't me! ;-)

Could pick it up about 6 or 7 tonight if that would work for you...

06:30 [K1VVC] Ok - I've relisted the radio with the BIN price as you requested. I don't think 6-7 today would work for me. I'll be home all day tomorrow (until about 6PM). Thursday before 2PM would also be OK.

<Further confirming that we have a deal>

06:32 [K1VVC] For some reason it did not put a BIN price in the listing. I'll try again.

06:36 [AA4GA] Yes...I saw that! Just make it a real basic listing...no need for pix and such.

06:45 [AA4GA] Hi Jon - so that will make 175, with me picking up - if we end up not being able to meet, I'll send you another 20 bucks.

<Comment sent along with my pre-arranged offer>

06:46 [K1VVC] eBay has changed some of it's rules lately. To make an offer it has to be a fixed price listing only, not one with a BIN price. It should be OK now

<So I entered our agreed price as an offer on the eBay system before K1VVC even wrote me to let me know he had set it up>

07:28 [AA4GA (via email)] I should be able to get you PayPal as soon as you accept the offer...

I work until 4:30 or 5, and am about 1:45 from your place, so we'd need to get together in the evening.  If we need to get together earlier in the day because of your schedule, it would have to be on the weekend unfortunately.  But I really would rather pick up than ship...I don't really like to ship old, fragile items if I can help it!

It looks like I won't be able to make the Shelby hamfest this year, so the 2-NT is my consolation prize!

<As fast as we'd been communicating, I was a little worried at the lapse in time without hearing from him>

07:27 [K1VVC] Much to my amazement even before you submitted your offer I got an offer of $250. which I'm not going to be able to pass up. 

07:32 [AA4GA] Really? That saddens me greatly that you would renege on a deal. But, it (sic) that's the way you operate...good luck. 

WTF?? 

That just blew my mind!  Gentlemen don't reach an agreement and then back out.  I wondered if it was an attempt to extort a higher price from me, but no mention was made of me meeting or beating that offer, nor was I going to make one.  At that point, trust had been violated and no way I would I have purchased the radio.  But I was still on the hook as far as eBay was concerned, but finally at 09:21, I got official notification from eBay that my offer had been declined.


So, my recommendation for dealings with K1VVC is to be very careful.  In my case, I'll just stay very far away...you decide who you want to trade with.  Oh, in addition to "radiotyke", he seems to also use the eBay seller account of "jonweiner-k1vvc"...and he seems to be active some on qrz.com, eham.net and qth.com.  

TenTec Rebel & the QRP Skunkwerx Universal Shield

Huntsville Alabama has a great hamfest every August.  In addition to a nice air conditioned indoor boneyard and loads of commercial vendors, Craig, NM4T, puts together a great slate of QRP-related forums.  Not only that, but he also hosts a gathering of QRPers on Saturday night at nearby Monte Sano State Park.  The festivities include an FB BBQ, along with an event or two.  This year, one of the events was the "Huntsville Rebelthon".

Craig, along with Glen, KW5GP, and some others, have formed the QRP SkunkWerx - a design group that, so far as I know, has concentrated primarily on expanding the TenTec Rebel Open Source QRP Transceiver.  The SkunkWerx have come up with a "Universal Shield" for the Rebel, and have pushed the little rig beyond its CW limits by coaxing the rig to work on JT65.

The Rebelthon was limited to a handful of Rebel-owning participants.  Glen provided the Universal Shields, some miscellaneous parts to slightly modify the Rebel, a Nokia 5110 display, the wiring needed to hook it all up, the revised sketch, as well as assistance and general moral support for several of us to start down the road of personalizing our Rebels.

SkunkWerx Universal Shield and Bandswitch Mod
The SkunkWerx mod involved replacing the SPDT on-off switch with a DPDT-center-off switch to enable hardware bandswitching.  The switch sets the band jumper open or short, which tells the chipKIT UNO32 which band the rig is on.  In my case, the bandswitch is wired so that up is 40 meters and down is 20 meters - center is off.

The band changing requires that the DDS tune the appropriate frequency to mix with the IF so the rig will tune on the chosen band.  Also, the appropriate bandpass filter must be selected.  As the rig comes, the bandpass filters are selected with four jumpers.  The SkunkWerx Universal Shield uses two latching relays to select the proper filter.  The RebelAllianceMod does much the same, but with a couple differences.  First, they do not use latching relays - when powered, their relays will constantly consume power - not a lot, but for a QRP rig that often runs on batteries, every little bit helps.  The other difference is that they use a long press of the FUNCTION button on the Rebel to change bands. This has the advantage of not having to re-start the rig when changing bands.  Perhaps someone will incorporate that switching method into the SkunkWerx sketch.

That's one of the beauties of Open Source - many different people contributing different solutions to the same problem - and having these solutions available, others can combine them in ways that appeal to them.

SkunkWerx Nokia 5110 Display
Back to the Universal Shield, the SkunkWerx have included a connector for a display, and there are options for a variety of display types.  Their sketch includes code for the Nokia 5110, as well as a "standard" LCD...which is included in the original TenTec sketch.  Glen provided a Nokia 5110 display, and the information that their sketch provides is shown to the right.  Namely, TX frequency, RX frequency, RX Bandwidth, DDS Step Size, and frequency Band.

At the Rebelthon, Glen made sure everyone had success in modifying their on/off switch into a bandswitch, and also had all the jumpers wired in correctly.  He then uploaded the SkunkWerx sketch into each rig, and tested to make sure all was well.  In my case, the bandswitch was a little flaky, so Glen pulled another pre-wired switch out of his stash and we had my rig flying right in just a couple minutes.

So, with a big push from Glen, it was time to get down to playing more with the Rebel.  As the Rebel comes, it's an OK, but not great, QRP rig.  Certainly adding a display adds a lot to the enjoyment of using the rig.

One of the first things I noticed when I got my Rebel was how bad the RX sounded.  Listening on earbuds was extremely uncomfortable.  There is also a fair bit of noise just from turning the main tuning encoder - or pressing the switches or turning the RIT knob for that matter.  I know that Michael, KD4SGN, had some similar experiences with his Rebel and has made some modifications that have helped.  I need to get with him to learn about what he's done, but in the interim, I decided to connect a speaker to the rig, and the radio is now usable - not the equal of the Drake R-4, but at least now I can stand to listen to it.  In fact, I'm listening to a bit of DX on 40m as I type this.

With the sound of the RX tamed down a bit, I felt better about messing with the sketch.  For starters, I find the Rebel's Wide and Medium bandwidths pretty useless, so I changed the default bandwidth from Wide to Narrow...pretty easy!  Another thing I didn't like about the Rebel is that the finest DDS step is 100 Hz.  I knew 10 Hz steps would make for a more analog-VFO-like experience, and allow me to tune the pitch in just so.  Well, it is easy enough to change the tuning steps, but the Rebel's encoder is so coarse, that the tuning rate is much too slow when using 10 Hz steps.  So, back to 100 Hz for now.

Now, on to the SkunkWerx sketch.  The first thing I didn't really care for with Glen's display was the lack of decimal points and thousands separators on the frequency.  A frequency readout of 14021035 was just too much for me...I could much better deal with 14.021.035 and would prefer 14.021.0 or .04.  Well, one thing I learned was that putting those decimals in isn't the easiest thing to do!  I tried several different methods, but never came up with anything satisfactory.  So, I changed the display to read in KHz, with no thousands separators and no fractional KHz.  Again, not ideal, but something I can re-visit in the future.

Next, the Nokia display is pretty small, and the library Glen used results in six lines, so the type is small as well.  Part of this is because of all the information displayed - Glen uses five of the six available lines. Looking at all the info displayed, really a lot of it is redundant.  I didn't need the Band - that info is available from the frequency readout.  Likewise, the Step Size and Bandwidth are both indicated on the radio's front panel via LEDs, so that could go.  And the main advantage to me for showing both TX and RX frequency is to see how far from zero the RIT is tuned - the RIT doesn't have an "off" position, so it's easy to bump the knob and be a few Hz...or few hundred Hz off frequency.  So, some kind of RIT display would be nice.

AA4GA 5110 Display - as of early September 2014
For my changes, I initially removed everything but the TX frequency from the display.  I then changed to the largest numeric font in the 5110 library, which is effectively three rows high....resulting in a nice, easily visible frequency readout.  Below that, I added a numeric indication of RIT tuning +/- in Hz.  To make it more readable, I skipped a line below the frequency.  That still left a line free at the bottom of the display, and I decided that would be a great spot for an S-meter bar graph.  So, I added that using asterisks for the graphing elements.  I would prefer something more "solid", but that can wait until another day.  I am also displaying the raw signal strength provided by the Rebel so I can get a feel for how high the numbers actually go.  Someday I may use this for "calibrating" the S-meter, but for now, it's nice to just have a relative display of received signal strength.

I do want to mention that my fault-finding of Glen's display isn't a negative reflection on Glen - he actually designed this as a springboard for others to mold into their vision of what the rig should be.  In fact, on Glen's personal Rebel, he's using an OLED display...an option worth considering!  In fact, Glen is not only a capable programmer, he has recently authored a book on using the Arduino for Ham Radio that the ARRL has just published.  I bought the book and have ordered sensors for some of the included projects.  Glen's motivation is definitely educating people on using the Arduino (and by association, the Rebel).

So, if you've got a Rebel, consider using the SkunkWerx Universal Shield and sketch as a start for your own Rebel excursions.  The complete SkunkWerx sketch and documentation of how to build the Universal Shield are available at the Rebel Yahoo Group's file section.

My main purpose in getting the Rebel was to use it for learning about rig control (primarily VFO and display) for use in some future home-brew projects.  I think the rig will come in handy for that and will provide me with a playground to test different ideas - I've already got several more that I want to try when I get around to it.

Thank you to Glen, Craig, and all the SkunkWerx....and to TenTec for the fun toy!

MacLoggerDX

With the acquisition of a Mac Mini to replace a very tired Windows XP laptop, came the need to convert my daily logging system from Logger32 to an OSX solution.

I have used Logger32 for a long time, it has a decent feature set, and is highly configurable.  Relatively complicated to set up, but once that is done, it works pretty flawlessly.  There is good documentation by a dedicated team of folks, as well as an active Yahoo group that includes regular participation by the program's originator Bob Furser, K4CY.  As a DXer, it does everything I need a logging program to do...not as fancy as some of the programs out there, but the features it has are solid and useful.  All business, no fluff.

We converted to Macs at work about four years ago, so I'm fairly familiar with them, and have had my own Mac in my sights for a long time, so I'd done some research regarding logging software already, and knew there weren't nearly as many players as in the Windows world.  I also knew based on personal experience and anecdotal reports that I could probably keep running Logger32 in a virtual machine on the Mac, but did not want to do it that way if I could help it.  Keeping that as a fall-back solution, I wanted to run a native OSX application, so I began seriously looking for a logging program.

The two that seemed most interesting were RUMLog by Tom Lindner, DL2RUM and MacLoggerDX (MLDX) by Don Agro,  VE3VRW.   Both applications have user forums online in which the developers participate, but the MLDX forum seems to have the larger and more active user base of the two.  There are things about RUMLog that remind me of Logger32, and as freeware, the price is right, so I decided to give it a try.  It's not a bad program at all, but I had had many recommendations to try MLDX, so I decided I would.

MLDX is $95, but has a trial scheme in that you can use the non-crippled program as much as you'd like prior to buying, with the only limitation being that the program times out after 15 minutes.  Fair enough, I can give it a try before buying.  The first thing I noticed is that 15 minutes is a very short time to spend with a complicated program when you don't know anything about how it works!  Most software packages I've run across will do something similar, but give you a two-week to 30-day trial period.  I can see advantages to both schemes I suppose, but when actively evaluating, the 15 minute sessions are a PITA, but I sat down with the program, manual, and online forum to give it my best shot.

After importing my 5000+ QSO QRP-only log from the past three years, the first thing I noticed is that the QSO entry area is very busy on MLDX.  There are fields that, IMO, just aren't necessary to display for average QSOs.  For example, in addition to "normal", expected fields such as First Name, State, Frequency, Mode, Reports and Notes,  there are questionable fields such as Last Name, Street, City, State, Email, IOTA, SOTA, 10/10, etc.  MLDX pretty much assumes the user will be using an online callsign lookup service such as QRZ.com.

Also, the formatting of some items is fairly questionable as well.  Particularly, the Time fields are a full timestamp displayed as YYYY-MM-DD HH:MM:SS.  That is very busy to look at and needlessly detailed for most purposes.  But I figured I could live with it - IMO though, it just detracts from the appearance of the log - a log whose main advantage is it's appearance.

Another problematic item is the Notes or Comments field.  It is automatically populated with a bunch of needless "stuff" when doing a lookup on a station.  For instance, the following was entered with no prompting from me in the last QSO I entered into MLDX:

Class: E, efdate: 2005-02-01, expdate: 2015-03-17, GMT:-5, qrzloc:user, Uploaded to ClubLog 2013-11-22 02:16

Whew!  Now, there may be a flag in the preferences that allows me to turn this off, but I never did see it.  But really, why would I want to put in my log when the other station's license is going to expire?  Crazy.  Just because some information is available doesn't mean you need to log it!

But I kept looking at the program, and while it did do some fairly stupid things, it did some other things very nicely indeed.  There is a Stacking register that allows you to keep up with calls/frequencies and easily tune back to them which is nice.  There are a lot of map options that are fun.  Like most hams I think, I like maps.  While the Grayline map was OK (although it should be a vector image like most loggers use, rather than a bitmapped image), especially with the ability to plot spotted DX stations, the map I was most enamored with was the Google Map - the station worked is plotted on Google Maps, which can be zoomed in or out to get an idea of the other station's locale.  When I was a new ham over 35 years ago, I remember looking up all my QSOs on a map just to see where French Lick, Indiana was or whatever - great fun, and this automated it.  Nice.  In fact, this mapping feature is probably the single feature that made me decide to send Don Agro my $95.  I figured all the other weaknesses I'd encountered to date were tolerable, and/or were simply a matter of me not setting the preferences correctly yet.

So, I paid my 95 bucks and started using the program.  Don Agro was very quick to issue me a registration number and I was off and running.  The first thing I noticed after the program had been running for an hour or so was that my display of DX stations in the Spots window was not showing much in the way of useful spots.  Almost all the spots were countries and band/countries I'd worked before.  So, I started digging into the preferences, the manual, and researching old posts on the Yahoo group, but I could not figure out a way for the Spots window to display only new countries or new band-countries.  Instead, it was showing every DL, G, I, etc. that had been spotted, which cluttered up the Spots window tremendously.  While the spots were color coded, each of several columns had to be reviewed for each spot to determine whether or not it was a spot of interest.  So, I posted a question about this to the Yahoo group and was quickly answered by Don Agro, who basically said that the filtering I was looking for was unavailable.  I then asked that a feature request be considered to allow such filtering, as without that, the Spots window is very difficult to use.  At that point, I was quickly admonished by Don Agro that it was an inappropriate use of the Yahoo group to post feature requests, and that any posted in such a manner would be ignored.  And, fair enough, that information is included on the group's "About" page and I'd missed it.  So, I apologized and sent a feature request directly to Dogpark Software and Don Agro.

And that is when the shit hit the fan.

Via a rapidly-deteriorating exchange of email between me and Don Agro, I was told that I was the only one who had ever made such a request, that my request was "nonsense", and at one point "Feature bloat is the single worst thing a Mac application can be accused of".  Which is really pretty funny if you look at the program on a whole and see all the useless things that it does do in an attempt to be pretty vs. functional.  At one point in the exchange Don Agro, to his credit, offered to refund my money, which I thought was more than fair, and a bit surprising actually.  This was after he had said he wouldn't add the filtering capability that seemed so basic to me.  So, I decided to see if I could successfully install a virtual machine and get Logger32 running acceptably on my Mac, and if I could, I would probably take him up on his offer.

A few hours later, Don Agro sent me an email stating "Version 5.50 Beta 64 has worked and confirmed filters added but I would still be more than happy to issue you a refund. I don’t need your $95.00".  Wow, what a class act!  That pretty much made my decision for me - I would put up with the limitations in RUMLog (which really is a good program and not all that limited) before using MLDX!  Hell, I would resort to a pen and ink log before using MLDX!  (OK, that's not much of a stretch - except for contests, I still keep a paper log - I'm a fountain pen user/collector!)

I had been warned that Don Agro was a bit of a curmudgeon.  Bob Furser is too, and so am I.  But I think it's more than curmudgeonliness in Don Agro's case - I think he may have some issues that could use professional attention.  He certainly does not know how to address customers.  To his credit, Don Agro did rapidly refund my purchase price when I accepted that offer.

So, I downloaded Parallels and installed Logger32 on the Mac, and am working along very nicely indeed, with all communications between the radio, keyer, and software working exactly as they should.  Parallels works well with OSX's new full-screen mode, and I've got my smaller monitor off to the side with full-screen Logger32 and the big monitor used for Mac stuff and everything is working great!  No, it's not as pretty as MLDX, and doesn't have quite the same feature set, but it does what it should do, and does it well.  And the developer isn't an asshole to me to boot!  Life is good.

MLDX may be a good choice for you - I will warn you to test it fully before buying.  Oh, and one more thing:  I wanted to leave my install of MLDX active on my machine until I finished this review, before deleting it forever.  So, when I started writing the review, I cranked up MLDX to review how it did some things, and after 10 minutes, I got the familiar "this trial will stop after 15 minutes" pop-up.  Wow, Don Agro has the ability to rescind MLDX registration even after you've purchased the program.  So, if you really piss him off, be warned, he could disable your registration at any time.


A little addendum:

OK, so I saw nothing in the manual or discussed in the Yahoo group about uninstalling MLDX, so I decided to post a final message to the Yahoo Group to make sure I was getting everything removed properly.  Well, I already realized this was a private group and thought all posts were moderated by Don Agro himself, but figured I'd ask anyway.  Here is the automated response I got:

I did not see any instructions in the manual referencing removal of MLDX, nor in any of the messages here.

Other than deleting the application file, I see there are four dogparksoftware entries in the Library/Preferences to remove, as well as the log and some associated files in a directory in my Documents directory.

Is there anything else to remove/do to delete MLDX from my Mac?


Having previously posted a few messages successfully to the group when evaluating and installing the program, I can only surmise that number two is the reason my message was not accepted.  Nice.

CW Open 2013 QRP Team

This is a quickie about the CW Ops CW Open contest that is coming up on 8/31.  Actually, it is three contests in one - there are three four-hour time slots in a single 24-hour day - each of the three periods is scored individually, as well as an aggregated score.  The CW Open has team contesting, and last year we put together a team of QRP-only operators.  It was so much fun (and we didn't come in last place!) that we're doing it again.

Szabi, VA2FDT, was also working on getting together a QRP team, so we've joined up our efforts.

Here are the two teams we've put together:

AA4GA - March 2013


The local radio club (Athens Radio Club) is having a "show off your shack" show and tell at the next meeting and asked everyone to send in pics of their shack...so, this is mine as of the middle of March 2013:


ARRL International DX Contest 2013

Like last year, the condx seemed to go down a bit on Sunday compared to Saturday. This year seemed a little worse than last - hard to say though. One thing that was down this year was BIC time - only about 18.5 hours compared to 24 hours last year. I did pick up a couple extra mults compared to last year, but QSOs and points were down slightly. But this was with 25% less operating time, so either condx were actually better this year, or the station was better. I'm voting for the second. The weekend before the contest I put up a full-sized 40m ground plane, with the feedpoint up about 12' or so. This antenna consistently beat the 80m doublet into Europe on 40m, so it got a good bit of use. Also, on Saturday, during the contest, I put up a trapped EFHW for 10/15/30.

This antenna has generated a number of questions, so in case anyone else is curious, here's a little more info. The Cushcraft R-series of electrical half-wave antennas has always gotten mixed reviews, but I think overall they are a good idea. But I didn't want to shell out the money to try one in case they really were dummy loads. So, I figured why not build what I wanted? Since the R-series are effectively half-wave antennas, they have a high input impedance - this is corrected for with the large base-mounted matchbox that comes with the antenna. A similar arrangement exists for the Par End-Fedz 10/20/40. It is a half-wave on 40 that has a broad-band matching transformer used at the base; in the Par literature, they even mention that this matcher may be used for single-band antennas by simply replacing the wire with one appropriately sized for the band of interest. The 10/20/40 resonances all stem from the fact that these bands are harmonically related. My idea was to build an R-3(-ish) antenna with a trapped half-wave element to allow operation on 10/15/30m. 10 and 15 because those are the bands I need to pay attention to for my 5BDXCC, and because my antennas from 20m on down seem to work OK as is...and, I was anxious to get back to the contest and didn't want to bother with tuning the new antenna's low band up to 20m.

In March 2012, QST published an article by W6NBC titled "Better Coax Traps", wherein the author presented an alternative method of coax trap construction that was free-form, rather than using PVC or some other form on which to wind the traps. This looked like an easy method, so that's what I did, using the VE6YP trap calculator. I used RG-174 to build coax traps, and was aiming for a frequency just below the targeted bands. Not having a way to measure the trap resonance, I just put an antenna together and checked SWR - generally the SWR was OK after trimming the 10m section to lowest SWR, but could be better. I will likely trim the antenna closer to resonance on all bands, and also am planning on trying some different traps. Before doing too much with the traps though, I'd like to buy or build a dipmeter so I'll have a reasonable way to check the traps' resonant frequency. Oh, I also fed the antenna through a Par End Fedz 10/20/40 matchbox, as I had one laying around, not in use. There are a number of plans for a similar matchbox on the internet...Google is your friend!

I hung the antenna up as a vertical, with the feedpoint up about 10 feet or so. How did it work? At first, on 10 meters, when the band was just opening, the 80m doublet sounded better than the wire vertical. But, within a half hour or so, the band settled down, and the the vertical was actually better to Europe about 95% of the time, and the advantage was usually at least two s-units - at times, the advantage was 4 or 5 s-units. Performance like that makes the antenna a keeper - I do hope to do a little more tweaking on the antenna before next fall.

For the contest itself, I operated about six hours less, and got a couple more mults, and otherwise, my score was down only slightly compared to last year. The bands seemed a little worse, but with the new antennas, it was pretty hard to tell.

Here's the band breakdown:

Band QSOs Mults
80:   30   26
40:   85   47
20:   91   51
15:   87   44
10:   58   35

Tot: 351  203 Total Score = 213,150

Down a little less than 5%, with only 75% of the operating time - I'll take it!

KX3 at 5 watts, 80m doublet at 45', 40m Ground plane fed at 12', and 10/15/30m trapped EFHW, hung vertically.

MagicBox

The Four State QRP Group (representing MO, AR, NE, and OK) sells a number of neat QRP kits including the K8IQY MagicBox, a T/R controller that lets you connect a QRP transmitter, receiver, antenna, and key and gives back full- or semi-QSK, RX muting, and sidetone. It provides an easy way to interface all sorts of little transmitter and receiver projects so that they can be easily used on the air. The Four State website goes into greater detail.

I got my kit from someone on QRP-L who decided not to build it, and found that the kit was well documented and went together easily and quickly. I tested it and made a QSO using a Tuna Tin 2 I'd built up Manhattan style. The board is designed such that no enclosure is needed and uses PCB-mount jacks for all connections, so it was easy to try without an enclosure. Which was great, because for a lot of us, finishing the project by mounting in an enclosure is the hardest part. It certainly is for me, and I had a bare MagicBox for months.

 I left it at work, thinking I'd be able to get one of our shop guys to help me with it, but that never happened. I finally conned NA4SO into helping me drill the holes, but we did run into a problem with the drilling template. It was a little off, although I thought I'd confirmed it was OK (measure twice, cut once!). Not too bad though, and the easiest solution was to pull the BNC jacks off the board and use panel-mount jacks.

 I set mine up with a power LED, a semi/full QSK switch, spot switch, and tune pushbutton. The only problem with any of this was with the spot switch - the early kits were supplied with a "bleed-through" resistor that was too large a value - I paralleled a 100 Ohm trimpot with this resistor and now the spot function works as it should...with the added benefit of being adjustable...this could even be routed to a pot for front-panel control if desired.

Right now, I'm using my old Drake R4 for an RX, but eventually hope to build something up from scratch.  All-in-all, I think it's a great kit and well worth looking at if you need to interface QRP "seperates".

A Case for the KX3

Not an argument extolling the virtues of the radio - it does that pretty well by itself.  Instead, a physical case for carrying the KX3.

I still haven't taken my KX3 out in the field to speak of...although I did carry it to NA4SO's shack last week, and apparently while in my pack, something banged into the RIT knob and cracked it.  I only had the rig in a thin neoprene shell, and there were a couple of heavy crimpers in the pack, one of which I'm guessing banged into the KX3 - glad it didn't hit the clear bezel!

So, I'm trying to get back to deciding what case would be best.  I'm looking for something that protects well, but I don't need - or want - a bunch of extra compartments for carrying "stuff".  I just want good protection for the radio itself, and for that package to be as small as possible for SOTA hikes.

Here are some possibles:

 This case is being used by W7GJ.  I think it would be great for carrying the KX3 along with more stuff...but that's not what I'm really looking for.  This bag doesn't look ideal for using in conjunction with a backpack, which is what I need.  Although, I've had a number of LowePro bags over the years and always like them, so I'd say this is definitely worth considering if you have the need for this type of case.








Here is a better candidate for my needs, and one I'm giving serious consideration.  It has a better form factor, and while having some extra compartments, the bag isn't grossly over-sized.  I learned about this one from G4ILO, who apparently learned about it from N6KR himself, so it's got to be a good candidate.









Obviously something like this Pelikan would offer great protection, but it's far from petite, and the case alone weighs in at 2.5 pounds, so it's not exactly backpack friendly.  But I'm still looking at the weight vs. protection tradeoff and may go for it.

CQWW CW - 2012

Conditions this year seemed a bit down compared to last year....which is unfortunate, as this does not bode well for the remainder of this solar cycle.  It's starting to look a lot more like 20m and down will be where you'll need to concentrate antenna efforts for the next, oh, 30 years or so!  I'm writing this during the ARRL 10 meter contest, and that band is totally deceased.  I'm only a few short of 100 QRP countries on 10 and 15 - I need to get those knocked out this winter for a 5BDXCC, or it may be a really tough nut to crack!

I did have less butt-in-chair time this year, but that was most likely due to the worse band condx.  I also spend a bit of time comparing the FT817ND to the new KX3.

I definitely need to do some antenna work!

Elecraft KX3

I've been using a Yaesu FT817ND for just over 20 months as my primary rig.  It is pretty good for what it is:  a portable 5 watt radio that covers from 160 meters through 432 mHz.  It's really not a bad radio, but like most rigs, it has its own set of quirks.  Even after using the rig for a while, the menu system is a bit cumbersome.  The LCD display is small.  It's a good battery-powered portable rig, but draws a surprising high amount of current for that type rig.  The receiver is OK but not great - I've added a 300 Hz CW filter which helps, but the front end does kind of fall apart during contests, especially on 80m.  And for casual use, that narrow a filter can be uncomfortable to listen to for a lot of folks...even me, and I like a fairly narrow bandwidth.

Early this year, ND4V was kind enough to loan me an Elecraft K3, and I discovered it is the finest radio I've ever used.  A little pricey, but compared to top of the line rigs from Yaesu/Kenwood/Icom, it's really a bargain.  Around about the same time, Elecraft started shipping its KX3 - their latest portable rig, and it promised to be head and shoulders above the FT817 and any other commercially available QRP rig - either built or kit.  Many referred to the KX3 as a "mini K3".

I had had a chance to put my hands on a KX3 and knew that it "felt good", and was even able to operate one for about a half hour or so at the QRP gathering at the Huntsville Alabama hamfest this year and it seemed, at least ergonomically, to blow away the Yaesu.  Then in August, Rob Sherwood tested the KX3 and added it to his table of Reciever Test Data.  Wayne, N6KR, one of Elecraft's principles had mentioned the year before, pre release of the KX3, that he was certain the rig would be near the top of Sherwood's chart...and it was - it came in at number 1 of all receivers tested, even ahead of the K3!  Now the ranking is done based on dynamic range, which is only one measurement of reciever performance, but it is certainly one of the most important criteria, if not the most important.  It was plain from Sherwood's testing that the KX3 was something special:  Superb receiver performance that you can hold in the palm of your hand!

Bottom line is that I wanted a KX3 to evaluate to see if it was a worthy replacement for the FT817.  I felt sure it probably was, but I didn't want to just "drink the Elecraft KoolAid".  So, events transpired that I was able to acquire a KX3 just a few days before the CQWW CW contest...a perfect test!

The first night of CQWW usually goes a bit slow for me, especially now that I'm limiting myself to 5 watts and only have an 80m doublet up about 40 feet or so.  I figured it would be a perfect time to A-B the KX3 and the FT817.  I used a BNC-Tee to split my antenna between the two rigs.  I had an earbud in one ear from the Yaesu, and one from the Elecraft in the other.  I used the 300Hz filter in the Yaesu, and set the Elecraft's bandwidth to 300 Hz also.  I was pretty amazed at the differences.

First, the KX3 just sounded better.  It was cleaner - the Yaesu has always had a bit of hiss that the Elecraft really didn't have.  Additionally, the filter response of the Elecraft seemed much tighter than the Yaesu's - the skirts seemed steeper.  The Elecraft seemed about the same as the Yaesu as far as sensitivity goes, which means the rig wasn't the sensitivity limit, the band noise was.  But the KX3 could separate signals so much better than the FT817! I listened to a loud station CQing, and in the Yaesu, there was another loud station about 500Hz above that was easy to copy in the Yaesu, certainly loud enough to cover up weak stations - I couldn't even tell he was there in the KX3. Listening to the lower side, the Yaesu seemed a bit better, but still not as good as the KX3. In fact, I heard stations calling the CQer that were covered up by stations below the CQer in the Yaesu - in the KX3, I could still detect the QRM, but it was suppressed enough that I could copy the caller when it was impossible to do so in the Yaesu.

Ergonomically, the KX3 seems to do everything right - very little consultation of the manual has been required.  Most of that has been for setup of rig that is a bit out of the ordinary - and it's all pretty much set and forget stuff.  But the KX3 uses the same LCD display as the K3, so it is plenty readable.  The knobs all seem to do what you'd expect, and the alternate functions make sense.  All the buttons are plainly labelled.  The radio is very easy to use.

Now, for other niceties:

Dual Watch - very impressive and highly useful when calling DX stations that are working split.  I've found it so useful that I've dedicated one of my programmable function buttons to activate and deactivate this feature.

Output Power Adjustment - It's easy to dial in whatever power output you desire from 100mW up to 12 watts, no menu hunting needed

CW Delay/QSK - see output power adjustment

Bandwidth Changes - see output power adjustment - and you can crank the bandwidth down to 50 Hz - and it still sounds good that narrow!

Sidetone Level - see output power adjustment - sense a theme here?

Alternate VFO B Display - the biggest problem with this one is deciding *which* alternate to use.  For SOTA expeditions, I can see the clock, battery voltage, and current all being useful...but in that case I think the clock will win most of the time because of paper logging.  And at home, I'm sure the VFO B frequency will win.

I/Q Outputs - it's very easy to set the rig up an have a panadaptor type display: just connect a stereo cable from the rig to the sound card input on the computer.  I'm using NaP3 right now, and it actually displays frequency, and can control the KX3 as well when using a USB connection between the rig and the computer.  And do all the DSP if you'd rather use it for that instead of the KX3.  I've also just discovered LP-Bridge, which will allow the panadaptor display with proper frequency indicated and rig control via separate logging software.  Pretty dang neat.

There is a lot more that this rig will do that either doesn't interest me, or that I just haven't discovered yet (I'm about 18 days into owning it).  But I can say without hesitation, it is the finest radio I've ever owned.  The only nit I can pick with it is that the speaker is small, and it can be pushed into distortion/rattling.  But I've found that if I need to be listening that loud, I should probably be on the headphones - problem solved!

How does this radio do so much, so well, in such a small package?  It's pretty simple really:  it's all in the software.  You see, the RF part of the rig is really a direct conversion receiver.  That's about as far as my true understanding goes, but basically the signal is directly converted to audio and split into two signals that are out of phase(I and Q).  From there, the software works its magic - the radio is really an SDR - software defined radio.  What's different from the way many hams think of that is that the processing part is built into the radio's hardware rather than in a separate computer.  It allows for easy change and update of the radio's basic function with simple software upgrades (note that "easy" and "simple" are from the end users' perspective!).

The KX3 has performance that rivals and even exceeds all of the top of the line radios for considerably less money with one exception:  power output.  But, if you're a dedicated QRP operator, that isn't a limitation at all, and in fact, you're not paying for something you won't use.  Elecraft is working on an external power amp for those who are interested in using this radio at a higher power level, but it hasn't been released as of this writing.

My FT817ND will be for sale soon.
