[Elecraft] KX3-2M module will work well for CW and SSB, even as an I.F. for higher-band XVTRs

[Dave]

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...
