[Elecraft] Re： SCS Pactor 3 modem with K3

Thanks Markus.

It is a pitty that K3 cannot work properly with the best pactor 3 modem.  HF 
email is now one of the cheapest and reliable way in marine and ARES.
 cheers,

AFAIK the PTC-II controllers do not "speak" K3 CAT commands, therefore the
"TRX Control" port cannot be used to control a K3.
Consequence: No frequency scanning (controlled by the PTC-II).

The audio part between the PTC-II's "TRX Audio" port and the K3 is
straightforward:
PTC Audio output (pin1) to K3 Line in
PTC Audio input (pin4) to K3 Line out
PTC PTT output (pin3) to K3 PTT in
PTC GND (pin2) to K3 GND ;-)
