Dom,
If you plan to do K2 work repetitively, making up a "microphone pinout"
change box would be handy.
However, that does not fully address the problem of the bias resistor.
In order to test properly, you would need one (or more) dynamic
microphones like your Yaesu MH-31, plus you would need an electret type
microphone, like the Elecraft MH2/3 or one of the Icom microphones.
I myself would be reluctant to simply change the plugging of the
microphone configuration header and then ship a K2 to the customer
without having the ability to test that change.
If this is a one-time build for another ham, I would ask him to send his
Icom microphone to you.

Dummy question...
I've got a K2 serial c5500 added the KSB2 module I have a Yaseu mic
MH-31 (No additional pre-amp fitted) will to do the SSB test and
alignment with it... however the K2 is going to someone who uses an
ICOM mike, type unknown. (Yes will need to know if need to add pin 2
for a pre-amp...checking)
Anything that might be very different between them from those in the
know that would make alignment with one irrelevant for the other?
I'm pretty sure I will have to wire differently on the unit for the
inital mike and the final one (bit of a pain ho hum), apart from the
jumpers and details listed P17/18 in the KSB2 manual.

Or anyone suggest suitable tests just to make sure it is all working
fine? I could think a PTT and/or an up/down break out board and
switches might be worth doing?
