[Elecraft] KX3-2M module?

Yes, and No, to be unhelpfully exact...

My TS2000X is "off" by about 1.7kHz compared to other peoples 'dial' 
settings on 1296MHz.  I know this and I compensate, but the higher up the 
chain you go, the worse the problem gets...

Since I have another radio to "do" 2M on (TS2000X) I'm only looking to use 
the KX3-2M for two things.  1. The occasional use in the field, or from a 
hotel room (though not so much that to be honest) where I agree, I can 
probably compensate manually, as long as it doesn't drift too far, too fast 
but the other reason may be a game killer, as far as I'm concerned.

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.

So, no, some of us do care and unless the KX3-2M can at least match 
something like the 2M stability of the FT817 (which isn't all that great 
anyway) then this wont be something that many serious users of 2M gear will 
accept as being "OK".

Back in the 1980s there were radios on 2M which were well known for their 
drift and lack of a good output on 2M, even on SSB, and I'd hate to put out 
a poor signal on 2M CW from an Elecraft bit of kit.  That really could 
damage the company name with potential future customers and provide 
amunition to their competitors, in my opinion.
