David, Yes, AM transmission would be possible (but not practical) - by pass the filter on the KSB2 board and unbalance the carrier balance pot - but be careful not to overdrive the balanced modulator or any of the following stages - the carrier will be there constantly, so you have to keep the power output low (I would guess about 4 to 5 watts max).
Reception is a different matter - replace the product detector with an AM detector and add some AF amplifiers to bring the detector output up to something usable. This would be a real 'butcher job' on the K2, but it could be made to work. As I said - possible, but not practical. Boatanchor AM transmitters and receivers would be a better choice IMHO - you could find a plate modulated transmitter and have great sounding AM. 73, Don W3FPR > -----Original Message----- > > How complicated would it be to add AM capability to the K2 (TX+RX)? > > I have operated AM on 10 meters on my Icom 730 and it was fun.
