Hello Chris, all,=A0

This looks like a MSK signal to me, like i had at 136.6 kHz (153 kHz - 16.= 4 kHz). Your IF is 128 kHz if i remember correctly so the signal appears= at 11 kHz. Hm, others may find the dependency...=A0
This kind of signal was not visible before some weeks so maybe the input= stage (1st FET) was a bit damaged by a strong local thunderstorm (charged= raindrops)? I had the same problem on LF before some time :-( Now i am us= ing a band filter stage in front the first FET so the gate is grounded, DC= wise.=A0
