My 2000 seems to have weak receive. I have tried to peak all the coils. I seem to have trouble peaking the 455 kHz coils (L3,13,15 I believe). I use the Sam’s facts method with a signal generator inputting a 455 kHz tone to Gate 1 of FET1 and an AC VOM across the speaker coil. The issue is the voltage reading warlbles where I can’t get it to stay steady so I can tune the...
