[Elecraft] K3 synchronous AM detection

> BTW, I'm sure somebody will jump in and mention that the K3 can receive AM signals in SSB mode. This is true, but manually tuning across one of the shortwave bands (I want the "analog" experience) while listening to heterodynes whistling up and down does not make for a very pleasant listening experience!  ;-)
