Yes. If you connect a K3 to a KPA500 with the KPAK3AUX cable, and omit the "interrupter" that looks like a gender changer with a pin removed, you do not need a separate K3 to KPA500 key line. The required keying line is in the KPAK3AUX cable.
73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of David Inger In anticipation of receiving my KPA500 kit (July?), I had one question regarding cabling. If the AUX cable is used, does that eliminate the need for PA KEY cable. I assume it does since pins 10 & 12 of the AUX connector provide PTT. I would appreciate a clarification? 73 de K6SBA David in Santa Barbara, CA ______________________________________________________________ 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
