Tom, I use the KAT500/KPA500 combination with an IC-7610. The PTT line output from the '7610 goes to the KAT500 then to the KPA500. That is so the KAT500 can prevent the KPA500 from keying during a tuning operation or if the KAT500 detects the SWR is too high.

I do not see them in the Manuals or after a quick search online. I am looking at using a KAT/KPA-500 with a non-Elecraft rig. I want to make sure I understand how the PTT/Key-line switching works. I know there are some wiring diagrams in the manuals, but I am getting some conflicting information from them. If anyone has a setup using these with an IC-7600 or IC-7300, perhaps you would be willing to share your connections (may want to do that off-reflector). 73, Tom, KG3V ______________________________________________________________ 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 Message delivered to [email protected]
