Peter,
The XV144 was designed when the K2 was the primary intended driving
transceiver (the K2 did not tune above 30 MHz), and the XV144 design
point was primarily for CW and SSB operation on the low end of the band.
Since the K2 did not tune above 30 MHz (and did not do FM), there was
not much interest in having the XV144 output to be above 146MHz.
Enter the K3 with its FM capability and tuning above 30MHz and the
picture becomes "cloudy".
I do not know the range of the 28MHz nor the 144MHz bandpass filters in
the XV144, so I cannot directly answer your question.
Certainly the XV144 could be tuned to provide whatever coverage of the 2
meter band that you choose, but I do not know if the bandpass is
sufficiently wide to cover the entire band with full power output or
full RX sensitivity.

The datasheet for Elecraft's external transverter says that the IF
frequency is 28-30 Mhz. Does that mean it only supports 144Mhz to 146 Mhz?
What about other-branded transverters like the Down East Microwave? Can
they do the full 144Mhz -- 148 Mhz with the K3/K3S?
