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

[Dave]

Erm, yes, and yes.

I think that you need to think about what I said that I wanted to use the 
KX3-2M for before you try to reply to my complaints that it wont do what I 
want it to do.

I'm not using WSPR or any other data modes, other than CW, and that seems to 
be where we are getting confused...

Dave,

Are you using a frequency multiplier *applied to the I.F. signal*? If not, 
then any drift at the I.F., which in the KX3-2M case will be +/- 10 Hz, will 
simply be *added* to any drift in the final signal.

What I said was that this amount of drift might not be compatible with 
narrowband data modes. This would also apply to modes like WSPR, unless 
there's AFC in the algorithm that's tolerant of minor frequency shift. I 
haven't tried WSPR myself.
