I decided to take the bull by the horns and activate a SOTA summit on 6m only, using my newly-built Packer 6m 30W linear amplifier. The summit I chose was Tamborine Mountain, VK4/SE-059.
My rig this time was the Yaesu FT-817 and the antenna was a homebrew 6m dipole, strung up as a sloper.
As soon as I put out my first call, the game was on. In the space of a short 30 minutes I had made 15 contacts. Wonderful.
One aim of the activation was to test the amp, especially how long the battery would last as it draws around 6A.
At the start of the activation my battery had 12.58V, and at the end, 12.49V. That’s pretty incredible, especially seeing I was operating almost continuously. Input power from the radio was 1W and output 30W.
Another test I carried out (with Peter VK4JD) was to get an idea of the difference the amp made to an actual QSO. On bypass, with 1W, my signal was down some 20dB. So the amp was doing a fine job.
