[Elecraft] KX3-2M module?

Lance,

Wayne recently commented that they had some re-design after the first 
field test round, and were soon to go out with the second field 
test.  I wrote Wayne directly for more info, but have not heard back, 
as yet...I signed-up to be a field tester so am hoping that I may 
have one to test when that happens.

I will be testing it and the KX3 especially looking at use for eme 
and 2m weak-signal operation.  I am lucky to have a couple RFC 2-23 
linear amps (2w input/30w out) which will match up with low power 
level of the 2M module.  That will drive another RFC linear 
(30w/170w) easily to 55w to drive my 8877.  I presently use the 
latter amp so my DEMI transverter can loaf a bit when running JT65 with the K3.

I have the test equipment to measure power and frequency to determine 
performance.  As in the past I will create a webpage to document what 
I find. I have not built a computer I/F for the KX3 so I will just 
simulate JT65 transmit by keydown CW.  I ran a freq. drift test on my 
current line-up by running JT65 for 30-minutes and noting frequency 
drift.  Its documented:

Hi Ray et al,

Many thanks for the status update!  I agree it is certainly a good 
thing to wait and
fine tune the hardware before officially releasing the product, and 
Elecraft does a
great job of that.   I will look forward to hearing more next month ;-)

I don't operate 2m FM myself, but it would be nice to have a backup 
2m exciter.  I
think if it could do 5w in JT65B mode, it should be able to drive my 
solid state amp
up enough to bring my 8877 up to 1500w output on EME.  ;-)  Provided 
it is very
stable....

VY 73, Lance
