FWIW, among other things it does an excellent job of emulating the K3's
Audio Peaking Filter (APF). The peak has variable gain and Q that can
literally pull signals down in the noise up into the clear.
Great addition to the K2 for weak signal enthusiasts.

I've just completed assembly and testing of my new KX1 and KX1AT.
I built s/n 1287 in 2005 and later traded it, with some regrets.
I have a few comments concerning the assembly instructions.

Diversity means one receiver in one ear and the other RX in the other ear.

When using Diversity RX is it better to set the SPKRs to 1 or 2?
I typically leave my speakers set to "2" (main and sub). I was thinking
that maybe in diversity that "1" may be a better choice.
Any comments?

These were critical functions in even

The bandwidth can make a difference - the noise is broadband while the

If the bandwidth of the receiver input is wide, then a preselector will

When you are in the mist of a storm disconnect everything.
The rules for grounding work much the same as the rules for anti-static
protection on the bench - keep everything at the SAME potential. Tying
antenna grounds to mains grounds means that you are not likely to see a
deadly potential difference between antennas or equipment even if, in the
