[Elecraft] KX3 Questions

Yes, the 2m module is a nice add-on; here at home, I use mine to drive 
transverters for 222, 902, 1296, 2304 and up. On 2m, with just 2w, I'm 
able to drive my SSPA to a full KW out (see the Oct 2012 QST article on 
the amp, or on the w6PQL web site).

I do notice an instability on 2m, and hope Elecraft will address this 
when time permits. You won't notice this on SSB or FM, but in CW the 
carrier frequency jumps around a few Hz in a random fashion. You can 
also hear this on the KX3 LO signal in another receiver nearby tuned to 
the same frequency; it's barely detectable at 6m, and not at all on 10m 
and below, but it does make 2m CW sound less than pure.

For me it was a great buy, and a replacement for older and less capable 
radios...I especially appreciate the ability to net transverter local 
oscillator offsets, and many of the other features.
