Re: [TenTec] Omni VI filters

Hi John,

No.  I'd have to make one and send off list.  The last photo I tried to 
send was too large and the message got tossed.   If you have a manual, 
the variable capacitor C-31 shown the picture of the logic board on page 
4-28 is the capacitor that changes the TCXO.  One needs to set/check the 
BFO oscillators as described on page 4-37 and 4-38.  I set the BFO 
oscillators using a frequency counter then I used fldigi in WWV mode to 
set the TCXO using WWV on 10 Mhz.  Mine is about 4 Hz off, but it's 
close enough for me. I'm going to leave it as is for the time being.
