Right! You want only ONE key line. Note that in Figure 3 (pg 13) the KPAK3AUX cable contains a key line inside of it. Figure 4 (page 14) show an external key line cable between the K3 and KPA500 so you can break into it to control some external gear such as a Stepp-IR antenna controller, but also shows the "key line interrupter" between the K3 and the KPAK3AUX cable. The interrupter opens the key line inside the KPAK3AUX cable so it's no longer active.
Every time I have to recable my K3/P3/KPA500/KAT500 setup - which is almost daily - I think to myself "Isn't wireless fun?"

In checking the AuxBus cables, I found a cable connecting the K3 Key Out to the KPA500 PA Key. Removing this cable made the fault go away. Perhaps I had followed the Figure 3 on page 23 of the KPA500 manual at some point. Anyway there is a lot of cabling back there. 73, Dave w0ru -- View this message in context: http://elecraft.365791.n2.nabble.com/KAT500-Fault-tp7608563p7608648.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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to r...@cobi.biz ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
