Hmm, Just in case others can benefit from my own stupidity:
The manual says hook up headphones, power and an antenna and go find a weak 20m signal, and then peak it up with the 20A and 20B trimmers. So I start tuning around at 11pm and the band is closed, so I decide to look for some QRM and peak up on that. I come accross a strong CW signal around 14.066 and I start fiddling with 20A and 20B. I can peak it with 20B but 20A doesn't make any difference at all. OK, I figure (from the manual) that maybe the AGC is working on it, so I go in search of another weaker signal. Great, found one. Again, 20A and 20B are making no difference. So I pull the antenna out. Signal is still present. Oops! It's an internally generated signal. Back to 14.066 ... that's still there too :) Ah, well. The moral of that story? If you're using a QRM signal (ie. a CW tone that may not be external, ie. it's not morse code), then disconnect the antenna to make sure it's not locally generated. Now both 20A and 20B can peak it up! Oops. Martin.
