I recently needed a new CW keyer with Winkey compatibility for use with my N1MM logging setup. K3NG has written some nice keyer code that I compiled and uploaded to one of my Arduino UNO boards that I had laying in the shack (if you want to try it, you need the latest – above 1 – version of the Arduino “IDE”). Below you can see some pictures from making the prototype thru to ready made keyer with USB interface and adjustable speed button. I did not install the memory buttons, as I control the CW keyer via USB from N1MM or Hamradio Deluxe. It works very well with my Yaesu FT-450D but instead of the UNO I will eventually use a Mini Pro board with the Atmel Atmega 328. You can see more info on K3NGs site http://radioartisan.wordpress.com/arduino-cw-keyer/#comment-3255
Below is the schematic (remark: full credit is given to to K3NG!). I have modded the design for my own needs. Instead of the 2N2222 I use a TTL tolerant FET of type IRLIZ44N to drive the keyer output. Then I don’t need the 100 ohm resistors in series. I also did connect a piezo tweeter directly to the CPU without using the 2N222 transistor. It works OK. However, the sound of the piezo tweeter is not the best in the world. Finally, as mentioned above, I did not install all the buttons. I installed only the command button to save space. There is a need to do a small mod on the UNO hardware due to some reset issues. For that I will have to add another button that needs to be pressed when I want to upload code.
I also needed a CAT interface. It is possible to use a FTDI chip for this task, however the signal levels need to be transformed to +/- 12V. This I solved with a MAX232 board that I had laying around in the shack. So now I have a CAT interface that is compatible with Win XP, NT, 2000, 98, Windows 7, Windows 8 etc since the FTDI chips are widely supported. It looks like … but works like …
Latest news: The 8S7X callsign has been allocated to LB3HC. 8S7X will be activated when operating from Sweden QTH. Stay tuned for more news.
We are back from the Azores Island Hunt expedition. Approx 31000 QSOs were made during 24 hours of operation from the 9 stations when a hardcore team of DX-ers and contesters visited the islands (unofficial ADIF numbers incl. eventual dupes). Nine stations running pileups on 40, 20 and 17m were on the air on CW/SSB simultaneously. The stations total run rate were in average approx 1300 QSOs / hour. Above I have posted some initial selected pictures from the event. We would like to thank OH2BH, OH8NC, CU2CE, CU2DX and all the local Azores hams that made this event possible. What a great memory for life we all got! What characterizes the Azores is great openings on HF. The reason the major contesters in the world choose to win from the Azores is the location almost in the middle between USA and South America. During daytime 10m, 12m, 15m and 20 meter openings are something else than experienced on more northerly latitudes (extremely good).

Here are some pictures from the WPX SSB 2012 at Radio Arcala. Enjoy!
CQWW WPX Contest, SSB
Operator(s): LB3HC, LA7JO, CU2DX, CU2CE
Class: M/S HP
Operating Time (hrs): 48
Total: 4139 Prefixes = 1379 Total Score = 11,906,286
Club: Contest Club Finland
Great to be back operating from Arcala now that the SSN is higher! All
operators: LB3HC, LA7JO, CU2DX, CU2CE had a great time and a lot of fun (as
usual from OH8X - Arcala).
Thanks to OH2BH, OH8NC and OH6KN for hosting us! Also thanks to the rest of the
Arcala team for making this possible!
This time we also had time to take some HD video and wide angle pictures of the
This time we had relatively good conditions up here at 65 degrees north
latitude in the ice and snow.
No significant technical issues were experienced.
This station station is professionally built by the extremely skilled guys in
the Arcala team. Kudos!
The Arcala antenna park is nothing less than extreme.
It was nice running with the new Yaesu FT DX 5000. Yaesu did it again!
We were likely affected by aurora at several time periods during the contest
that affected rates. We were unable to achieve runs at 40 and 80 to DX
locations and that resulted in that the DX runs was worked on 20 and 15. That
cost us 6-3=3 points per DX QSO and our average QSO points were below target.
Our target was to beat OH10X from 2011 and we wkd more mults, but somewhat less
QSOs corrected by the QSOs/36*48 factor due to condx and latitude (claimed
score). In fact 40 meter did not give good DX propagation at all. OH10X is
approx 500 km to the south.
We lost power due to a power company outage / spike at night and lost control
over all tower rotators and the voice keyer. It took several hours to correct
WOW! What a station and what a team. Contesting has got a new meaning.
