[Elecraft] K3 : AM synchronous detection

Check the errata sheet that came with the radio.  As features are added, 
they'll be listed in the firmware updates, viewable through the K3 Utility.

Not yet available.  You can use USB or LSB and FINE tuning for the 
moment, as the K3 is very stable and most AM transmissions are as well.

WIDTH refers to the fianl audio bandwidth.  IF is 1:1 to the IF 
bandwidth in CW, SSB and DATA modes.  AM IF bandwidth is twice the audio 
bandwidth.  FM will have a fixed IF bandwidth, at least initially, and 
WIDTH will refer to the AF response only.
