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). 73, Don W3FPR > -----Original Message----- > > just wondered if am would be possible with the k2 eventually .and > if it was how would one go about doing this. have heard a couple > am'ers on 80 a couple of times and it seemed awfully hard to copy > a qso ,not everyone was on perfect frequency . just a thought > _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
