Re: Ensemble RXTX Local Oscillator Stage
- Disregard my last transmission hi hi.
Stupid error in hookup to scope and frequency counter. I am seeing
what I should see from the secondary.
Apologies and Many Thanks,

I was looking at the full schematic and I can see the clock of the Si570 coupled to the primary via coupling cap C76. Looks to me that I should be able to see something of the oscillator at the hairpin of R12. I am seeing nothing. Am I missing something?
