Hi,
About your random frequency jumps, are any of the oscillator
capacitors silver-mica as they are known to cause this problem?
This was the subject of a discussion in one of the news-groups
just recently.
As for the changes in waveform, I would guess you have
insufficient isolation between the oscillators and the mixer
circuits - i.e. they are trying to sync-up each other as they
approach the same frequency.
Cheers - Joe
