Dear Roman,
Thanks for your feedback on our test with SAQ on Dec 20th 2024.

During the test transmission, we did a lot of tuning to try different methods and approaches to get a good and stable signal. Only for shorter periods of time, we ran with a steady signal, the rest of the time, we tuned, something you also heard. We also started up the “V” wheel, which is an original mechanical device from the 1920’s, which can produce the morse character “V” in an endless row. Initially the speed was very high but we were able to set it to approx. 20 wpm after some time.
Our morse code operator was also keying a short test message. We feel that we managed to get a strong and stable signal out from our antenna and everything looks promising for the Christmas transmission on Dec 24th.

The leakage in the magnetic amplifier can be as high as 10%, but we have not been able to measure it yet, it is a very difficult environment there with voltages up to 10 kV, depending on where you want to measure. We will work on getting these measurements done any time soon.
The output power is about 80kW to the antenna, we don’t want to magnetize the Alternator any harder due to its age.
At full power, 200kW, the antenna current is close to 100A in each vertical down-lead from each tower, however, for the last decades it has been set to about 35A.
The Antenna efficiency was originally 14% but nowadays it is more likely close to 10%, due to its age, meaning that we manage to get some 8kW into the ether at key-down.
