Hello Vlad,
sorry to hear about your problems, I do exactly know what you are talking
about, I have lost about 2 dozens FETs during my experiments. So good luck
and hope to receive a signal from you next time.

P.S.: A suggestion from my side: maybe you could move your beacon-test
frequency a little bit further off the very busy 137.700 kHz, maybe to a
range between 137.725 to 137.750 kHz or so, because there was a lot of
traffic going on yesterday night that would have covered your signal.

Agane fortune not stay with our LF experiment. Unstable insulator at
the
end of antenna damage one of our pair FETS in amplifier. I QRV QRSS20
beacon
137710 at 20UT only with driver power 7 Watts output. Antenna current was
300mA only.
I we are finde a posibility to bay FETS (we have a holydays now), will
continue with improved power. Not surre. Any way, will probe bepolar
amplifier 70 Watts out.
