Thanks for support, Holger! Yes, I lost IRFP460 FET, his coast seems near my
half day paying, hi! But main problem - closed shops today and tomorrow.
Well, I will transmit today QRSS20 137750, hope with improved power.
73! Vlad.

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.
