That's the ones someone sent me the link for. I ended up doing it a
little different. I set the BFO frequencies with a frequency counter
like the manual says. That was interesting since they seem to interact
with one another. When I did that, it really jacked up USB. The signal
sounded like it was barely in the passband of the filter. Adjusting the
TCXO fixed that. I ended up using WWV to set the TCXO. Assuming my
sound card is accurate, it looks like it's about 4 Hertz low on LSB and
dead on on USB. Every once in a while the pitch of the tone WWV is
transmitting will change for a fraction of a second then it goes back
where it was. Not sure the cause of that, but I'm going to leave it
where it is for now.
Thanks everyone for your help.
