Hello group,

I received a new KX2 from Elecraft  a few days ago and I am really enjoying
the little GEM!

As many of you already must know, the receiver performs brilliantly. I have
been comparing with a couple of SDR receivers in the shack and the KX2 is
preferred for weak signal reception in any mode.

I plan to use it portable of course, but for now have it set up in the
shack with an SDR receiver tracking with it as a panadapter.

I have noticed that the KX2 produces about a  -74dBm signal into the SDR
that is connected in parallel to the same Rx antenna (through a T/R switch).

The signal is offset about 8 kHz from the VFO , so the KX2 must use the
offset full time where it was a menu option on the KX3 I had?

For anyone using a similar setup I wonder if you see the signal at about
the same power level?

Am I correct that the nulling or supression is done at the audio stage
within the KX2 (because I can't hear it when I tune the 2nd VFO to it in
Dual Rx)?

Thanks Elecraft for another great transceiver and thank you all on the
group for being there as a great resource!
