Dave,
I do not understand how "a few Hz on 2M equates to a heck of a lot of
kHz on 24GHz"
A transverter is *not* a multiplier (it is a mixer). A frequency shift
at the input should produce an equal frequency shift at the output, so
any drift due to the 2 meter source should produce the same amount of
drift at the 24 GHz output. i.e. 10 Hz drift in the KX3 output would
produce 10 Hz drift in the transverter output no matter what the output
frequency may be.
Yes, there may be additional drift from the Local Oscillator in the
transverter, but that is a different story (there are likely frequency
multipliers in the LO chain).
So unless what you are referring to is something different than a normal
transverter, I do not understand your statement. Multiplying the signal
rather than mixing it with a LO will destroy any modulation, so you
would be slaved to CW.

and 2. As the IF for a 24GHz narrowband transverter. Now here things
do get critical. a few Hz on 2M equates to a heck of a lot of kHz on
24GHz after transverting and taking the stability, or lack of it, of
the 24GHz gear as well.
