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 ;-) 73, Markus HB9BRJ -- View this message in context: http://elecraft.365791.n2.nabble.com/SCS-Pactor-3-modem-with-K3-tp5803075p5803495.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
