SOTA SV/MC-033

On Sunday April 3rd my friend Paul, SV2HRT and I activated our first SOTA summit, SV/MC-033, Katsika at 643 m / 2110 ft. ASL We started from what looked like an easily accessible summit close by to start to get a feel for what we should expect on harder summits, as we do plan on continuing to activate more summits The access road was in a terrible state so we hiked about 1km to the peak. On this summit there is a radio tower (GSM mobile?) which must have been experiencing a power cut as the generator was on.

Although we brought along my Budipole antenna, we used a wire dipole antenna cut for 20m in an inverted V configuration. The RXTX used was my recently built SDR-Cube. At the time I thought the Cube was putting out 1W, but I later figured out that I made a miscalculation and the real output power was 250mW. 7 contacts where made on 20m CW unfortunately we did not manage to get the required 4 contacts with Paul's callsign SV2HRT. The time was getting late in the afternoon and it was windy and cold! We where not adequately prepared - A lesson for the next outing!

As it turned out everything we used in this activation was homebrew, rxtx, antenna, key. There is something very satisfying when operating with all your homebrew gear, especially in the field on the top of a mountain.


We will try to activate SV/MC-057 on Sunday 17th April. See you from the summit.

Bitx20 Completed main board and PA Board

I have completed the main board of the Bitx20 ver.3 from India. Tested it on the bench in receive and It works great. There was very little troubleshooting. By following Leonard's KC0WOX build instructions it went together smoothly and each section was tested as it was completed.

I listened to 20m QSO's for several days on it as I built up the PA board. Now I need to test it (PA) and get this rig on the air.
