The Elecraft ProSet K2 does use an adapter that is Kenwood compatible,
and will work just fine with the K3 or with a properly wired mic
configuration header on the K2.
The bias is applied to the AF output line and neither pin 5 nor pin 6
are used in the adapter.

I was perusing the Sherwood Engineering receiver evaluation
data, http://www.sherweng.com/table.html , and I noticed

than with the 400 or 500 Hz filter.
Then I came across some IMD
As others noted, that is not yet implemented in firmware.
However, you still have 1ppm accuracy. Use method 1 or 2 to set the
oscillator on frequency.
When it's implemented, method 3 will allow you to get even higher stability
by compensating in firmware for the known variation in the 1 ppm
So the bias voltage is nothing to do with where the 8v line is
on the front panel socket. Unless your mic requires the 8v line
which would only normally happen for desk mics (?) I do not see
a problem. The vast majority of desk mics will have a blocking
capacitor on the mic audio line.

I've had a chance to do a quick review of the beta

I've found it to be the most complete firmware to
date. About all I found missing was the squelch mode
for AM, whereas the control acts as RF Gain. At this
stage, that is really picking nits.
