Jim,
Yes, the lowest transverter IF is 7-MHz. Of course you can operate
the K3 in low power transceive on any frequency from 490-KHz to
32-MHz if in the TEST mode. Only issue is VFO readout is the IF and
not the operating frequency of a converter or transverter.
But say you use 3.472-3.478 MHz as your IF? Your LO would be 3.000
MHz. This could even be a DDS oscillator locked to a 10-MHz
reference. A simple mixer and LO without filters would work 0-500 KHz (maybe).
The wider issue if using other ham transceivers that only operate in
the ham bands.
My K3 has the EXREF board for referencing to an external 10-MHz
source. This enables 0.1 ppm accuracy. A 10-MHz LO is 1-Hz stabile.
