Hi LF I'm puzzled with the readings of bandwidth at the Op32 correlation detection grabbers As source I'm using a GPS generated signal, which is coherent in phase and works for EbNaut So I tested thi

Hello Andy, Could this in any way supply a reason for me seeing the odd dead FET when running OPERA and never when running WSPR? I always had the feeling that the fact OPERA stops and starts so many

Partly, perhaps, but I suspect your dead FETs could be due to antenna reflections of wideband transients of a hard switched waveform.  A sharp rise (or fall) time hitting a high Q antenna will cause

Hi Andy, Markus Thank you very much for the explanations on this issue I will modify the keying to avoid phase glitches and test again Have been running constant coherent carrier at 1W and could see
