And I don't feel like pulling my K3 apart; what's the OEM partnumber
of the power transistors on the KPA3 ? I couldn't find the KPA3
schematic on the elecraft web site.

I have a new K3 (s/n 2542).

I am finding that, after adjusting CONFIG: XV1 PWR the frequency of
VFO-A changes. VFO-B also changes, but by a much greater amount -
144.453 goes down to below 144 MHz.
Consequently, after adjusting CONFIG: XV1 PWR, I have to reset VFO-A and
VFO-B.
Is this normal, or is there a firmware
The D-104 is an excellent microphone for the K2 (and K3), Tom. Because
the ceramic/crystal element is high impedance, your best way of testing
it is to wire it up and try it. The pre-set gain control will need to

Thank you, Ron, for your explanation. I have carried out the mod as in
the App note. I was particularly puzzled by the resistor across pins 29
(TXD) 35 of P76 which appears to put the resistor between pin 14 of U1
and ground. I
