I want to pass along this info in case anyone else runs into this problem.
Got the K3 and KPA500 working well. It is a nice package. No problems. As I also have a SteppIR antenna I use a N8LP SteppIR Tuning Relay in series with the "Key Out" - "PA Key" line. I am using the KPAK3AUX cable set. When I try to hook in the PR6-10 I use the CTRL line on the PR6 connected to Pin 11 on the K3 ACC jack. When I do this I can't cycle the PR6 or KPA500. To fix this I used a gender changer between the "Y" cable going to the KPA500 with pins 10 and 11 removed. Make sure the KPA500 menu is set for INHIB IN DISABLE. I use DIGOUT1 to select the bands I want to use the PR6-10. I want thank AB7MY and others for their suggestions. So, now I am a happy camper. Got the K3/KPA500 working well for general operating. Got my Acom 2000A for contesting which is in the basement hooked up so a single switch changes amps. The DPDT switch controls a SPDT relay for switching the keying line to the amps and also switches two SPDT RF relays - one on the output of the K3 for the amp inputs and one in the basement switching the outputs of the two amps. 73, N2TK, Tony ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
