So why did a previous reply suggest that it would not be OK for narrowband
use?
Anyone who uses a transverter will know that, as the frequency of the lower
frequency used and the transverter frequency used changes then the
output/input of the chain will change.
The multiplication occurs as the chain of frequencies up to where you want
to get to multiplies and I really do not expect to have to argue this with
RF engineers...

Subject: [Elecraft] KX3-2M module will work well for CW and SSB,even as an
I.F. for higher-band XVTRs
There seems to be some confusion on this point. Once a KX3 has had the
extended temperature compensation procedure applied, it will have drift of
only about +/- 10 Hz in CW and SSB modes on 2 meters. This is not as good
as an oven-controlled oscillator (which there isn't room for, of course),
but it should be quite satisfactory for SSB and CW use.
If you use higher-band transverters after the KX3, using 2 meters as an
I.F., any drift in external units will add/subtract to the total, not
multiply the 2-m drift upwards. (Unless you're using a frequency
multiplier -- that's a different story.)
