[TenTec] Omni VI Mystery

[Steve Hunt]

Jim,

Try this simple experiment if you have a receiver that will cover 9MHz:

1) Take the top cover off the Omni (4 screws)
2) Place a piece of hook-up wire into the receiver's antenna socket and 
drape the other end near the Omni BFO board (at rear left on the omni). 
Don't short anything!!!
3) Set the Omni to LSB
4) Tune in the BFO signal at 9MHz on the receiver. Use USB on the 
receiver and tune for a fairly low audio note - say 400Hz.
5) Switch the Omni to USB temporarily to check that you are listening to 
its BFO and not some extraneous signal. The audio should disappear or 
move to a very high pitch (about 3kHz)
6) Switch the Omni back to LSB and hear the 400Hz note again
5) Now hit Tune on the Omni

If all is well, the audio pitch should increase to about 1kHz. I'm 
guessing with your fault it will hardly change pitch at all.
