The Hamshop.cz Open Keyer is a cute little keyer kit that is Arduino based and runs my open source keyer software.  It features a menu button, three memory buttons, a speed control, a PS2 keyboard connector, and a USB port.  The unit can be powered either through the USB connector or an internal 3 AAA battery pack.  A 1/8″ (3.5 mm) stereo jack is provided to connect your paddle and two phono connectors are for keying your transmitter key and PTT lines.

The brains inside the box is an Atmel ATMega chip running the Arduino bootloader, along with a USB chip.  Essentially it’s an Arduino and the normal Arduino development IDE can talk to it and program it.  As mentioned before it’s intended to run my open source keyer code, but it can be used with any Arduino code including your own keyer implementation. If you don’t need a PTT line for your transmitter, you can easily modify the source code to use the PTT port and a second transmitter keying port.

Most of the circuit is surface mount technology (SMT).  I hadn’t soldered SMT components for several years.  Last year I got my first set of reading glasses, and I found myself cursing the little parts, which in my more youthful years I’d have no problem working with.  This is no fault of Hamshop, just me whining about my age.  Luckily Hamshop pre-installs the ATMega and USB chips, so the most difficult components are taken care of for you.  The enclosure is a very simple but effective extruded aluminum two-piece clamshell or channel with two end pieces for the front and back.  Vinyl decals are provided for the front and back, and an instruction decal is provided for the top.  (Although my callsign is on the front of the unit, note that I did not design the hardware or kit.)

The unit performs well, though I accidentally left it on battery power for a few days and totally drained the batteries.  This prompted me to add a sleep mode feature to my code which is in beta testing and should solve this problem.  One minor issue with the Open Keyer kit is the front speed knob.  On my unit it does not fit well, with not enough of the potentiometer shaft exposed for the knob to grab on to. Ondra, OK1CDJ, at Hamshop tells me that they’re adjusting the alignment of the potentiometer in the next revision to address this problem.

I won’t review the actual keyer software as the documentation for this is here, and naturally I’m a bit biased about it, but it does about anything a CW aficionado would want to do.  All in all the Hamshop Open Keyer is a nice little kit that can be assembled in an evening or two, and is reasonably priced.

(Full disclosure / disclaimer: I do not have a financial interest in Hamshop, and I can’t provide support for this keyer hardware.  Support for the open source code is available on the Radio Artisan discussion group.)

Greetings AmateurRadio.com readers!  I have not written in quite awhile, so I feel the need to catch up a bit.  I’ve had so much going on lately that I just had to prioritize what time I have left at the end of the day.  I hope to be posting again on a more regular basis.

First of all, I want to mention that KD2CHE and I tied the knot back in October, on a cliff overlooking Lake Tahoe, on a beautiful (and warm thankfully) day in Incline Village, NV.  We were quite literally a stones throw from California.  The rest of our trip out west was great, including visits to two Silicon Valley surplus shops: Weird Stuff Warehouse, and Halted Supply Company (HSC), as well as HRO in Sunnyvale.  We even had a special tour of LucasFilms/Arts/ILG courtesy of some great friends with connections.  On the plane, on the way back, while leafing through a copy of Monitoring Times I purchased at HRO, I noticed that in an article about Ham Radio Kit Building, Kirk Kleinschmidt mentioned my Amateur Radio Kit Roundup as the source for info on kit building.  While it was a nice surprise, it also got me thinking that I needed to make the guide more accessible.  I will still post the changes here, but as a link to the guide’s new URL: RadioKitGuide.com.  For now it’s just a link to the page at my blog, but will evolve into a full wiki-style site in the near future.

My trusty HTX-10 has been busy these couple of months, logging calls to Alaska, Namibia, Croatia, New Mexico, Colorado, and California to name a few.  Mostly from the Crab Meadow Beach here on Long Island, but the Alaska contact was mobile!   A new addition to the collection is an Atlas 210X HF rig.  This was a holiday present from my better half.  After a couple of months of just listening, I finally put up a 35 foot random wire, and picked up an MFJ 941-D VersaTuner so that I could try and transmit.  It’s very close quarters where we live, so I’m limited in antenna choices, and have to worry about disturbing the neighbors (well, any more than they are already disturbed/disturbing).  I found out earlier in the week, that the setup seems to be very functional on 20 meters, and have talked to Mexico, and Florida so far.  I’m hoping for some good 10 and 15 conditions this weekend so that I can try it out up there.  I’m going to add a counterpoise to the setup and see if it helps me tune up on 40.  80 is out of the question for now, as I seem to obliterate my TV speakers and KD2CHE’s computer monitor when I even try to tune up.  My 5-cent 2 meter dipole has also been working well.  I’ll cover that in a later post.

Transmitter hunting has been pretty good, with the XYL and I usually finding the transmitter quickly, and rarely last.  What’s interesting about that is we are the only team in our hunting club that operates without a doppler.  I also will write a future post on our technique, which in our last hunt, guided us to the bunny way ahead of our technologically superior friends.  Unfortunately, as we arrived at the site, I assumed that we might have been wrong, due to the fact that there were no other cars from the hunters present.  Next time I won’t put my assumptions before my instincts.  In the end, KD2CHE was the one that actually found the box, by using her eyes, while a bunch of us wandered around the woods with our equipment.

That’s all for now.  Maybe I’ll catch one of you on HF this weekend.  73’s !

Instead of chasing 80 Meter Foxes, I decided to make an effort in the NAQCC 160 Meter Sprint that was held tonight.  Boy, am I glad I did!

Up until now, I really haven’t had anything that loaded up well on 160 Meters.  When I had my G5RV, it would load on 160 Meters; but barely and you could sure tell the radio wasn’t happy about it.

The 88′ EDZ is about the same. It will load up on 160 Meters; but the autotuner in the K3 takes a painfully long time to achieve a match. And then, if you decide to change frequency – even just a hair, the autotuner begs to be re-tuned.

The W3EDP, however?  I hit the autotune button and within what seems to be about a second and a half, I get a tiny little “BRRRRP” and a 1.1:1 match.  And I can tune around quite a bit without the radio complaining.  I know it’s not the ideal solution for 160 Meters; but it has allowed me to make more 160 Meter contacts in one night than I have in all my 34 years of operating combined.  Seriously, before tonight, I think my total QSO count on 160 Meters was maybe 3 …. 4 – maybe 5 at most?

I made 17 contacts tonight, my best DX being North Carolina, Illinois, Indiana and Ontario.  Not bad for 5 Watts to a compromise antenna, eh? OK, so the W3EDP won’t earn me WAS or DXCC on 160 Meters, but at least now I have another band I can go to when other bands seem dead.

And my good friend Charles W2SH sent me an e-mail the other day, informing me about a book soon to come out from the ARRL on 160 Meter antennas, specifically for those of us who are real estate challenged.  That is a must buy for me once the NJ Hamfest season starts back up again in March.

I just started up Google Chrome and my eye was caught by the minimize, maximize and close buttons in the title bar, which are bright red.

They stick out like a sore thumb. I can’t believe I wouldn’t have noticed it before. Is it just me, or my computer? If the buttons have changed colour, why? My eye is constantly drawn to these bright red buttons. It is a real eyesore.

The runaway success of the Elecraft KX3 has resulted in a sharp increase in the number of users of KComm. Even those who use a full-featured logging program in the shack find the simplicity of KComm and the compactness of its user interface (which was designed to fit a netbook) better suited to portable operating.

I received an email from a KComm user in Vienna, Wolfgang OE1MWW who wrote that he found the option to “Use PSK modem” (which uses AE4JY’s PSK Core DLL to operate PSK31 using the sound card) was disabled on his laptop running Windows XP SP3 though it was enabled on his desktop running Windows 7 64-bit. Wolfgang eventually found that replacing the file PSKCore.dll that was installed by KComm with one dowloaded from AE4JY’s website cured the problem.

I am surprised and a bit mystified as to why this occurred. My shack PC also runs Windows XP SP3 (I prefer to stay as far from the bleeding edge as possible) and it uses the same version of PSKCore.dll as is installed with KComm.

KComm’s version is much smaller so I’m hazarding a guess (since I can no longer remember) that it may have been compressed using UPX, an executable file compressor. I used to have a bit of a mania for compressing executable files so I could claim how small they were compared to certain other ham radio bloatware, but in these days of 100GB hard drives it’s probably rather fatuous. Possibly the compression caused an issue with some security software?

Whatever the reason, I’m grateful to Wolfgang for discovering a solution. I have added a note to KComm’s Troubleshooting page and updated the installer package to include AE4JY’s copy of the PSKCore.dll so hopefully new users will not encounter this problem.

It was time for me to go over the blog and do something that is never very easy to do.....I have had to preform this function in past and never looked forward to it. The time came to look through the blogs on my blog list and remove the ones that have been dormant for some time. As I went through the blogs I had noticed that some were without any activity for more than a year. I felt these ones for one reason or another were no longer functioning. It ended up I only had to drop about 3 blogs but it gives me more room to add active blogs. I can understand how workloads, family and sometime health problems can lead to a blog going stagnate. One thing I am guilty of is not changing my blog layout now and then to give it a new and fresh look. I think in the 3 years the blog has been up and running it has had....maybe 2 makeovers!! I should pay more attention to this as well as adding and or refreshing up the pages as well.
