[TenTec] Omni VI Mystery

[Steve Hunt]

Jim's getting RF out OK - it's just on the wrong frequency!

All the symptons - including the fact that he can "artificially" 
compensate using XIT - points to the BFO not being pulled to the correct 
frequency by the CW Tx line. The small number of components responsible 
for that BFO shift are the first place to look before searching for more 
esoteric explanations.

The fact that he's getting RF out also tells us that the connector 
carrying the CW Tx line to that board is good - that's what unbalances 
the balanced modulator.

Might be 100% wrong, God knows I’ve been before (I married my first wife) but I’m wondering if perhaps, just perhaps the filter (Transmit) has a ‘bump’ in it? Knocking the required signal out a hair, throwing the whole shebang under the bus. I’m guessing. A wild stab, whispers in the dark.
