[TenTec] Adding band to Omni D Series B

[Dr. Gerald N. Johnson, electrical engineer]

Depends on what the crystal and tuned circuits are. If the crystal added
is 4.0 MHz give or take a couple KHZ, there's going to be that strong
transmit spur. If the crystal is 22 MHz, its clean. Another check. If
set for USB on 20m and it receives upper on 17 meters, its going to have
the spur, if it receives LSB in the normal sideband position, its clean.
