Sean,
While AM transmit with the K2 would be a MAJOR change, it may be possible to
achieve AM receive - I haven't tried it, but D1 on the control board in the
AGC section looks a lot like a diode detector that might just be used for AM
demodulation. You may want to try connecting an Audio Amplifier to the
cathode of D1 and see what happens - the value of C2 may be a bit on the
large size for proper operation, so a bit of experimentation may be in
order.
I think I can assure you that AM transmission is not in the Elecraft product
plan - that is for the boat-anchor folks. You were likely hearing some
old-time transmitters and some do have a difficult time getting on frequency
(by today's standards) and many will drift more than is considered 'state of
the art' today. These WERE state of the art transmitters back in the days
they were in common use, but what was acceptable then is no longer OK on the
ham bands (except in specialized areas).
