[TenTec] Omni C on 17m

[geraldj@isunet.net (Dr. Gerald N. Johnson, electrical engineer)]

The question to ask is:"What sideband is the normal sideband in that
radio on 17m?" If its upper sideband there's a big transmit spur. If its
lower sideband there's no spur.

Its possible that it may depend on the vintage of the radio which side
the LO injection is on. If its high side its clean, if its low side its
dirty. A difference in the crystal frequency and VFO mixer output tuned
circuit. Possible in the same PC board with just changes in two or three
parts, the crystal and coil/capacitor.
