I'd love to see the KPA500 companion Antenna Tuner have a minimum of 5 antenna outputs which can be controlled automatically via the K3. This is the only way I'd purchase a KPA500 as otherwise I'll keep my Quadra which does automatic bandswitching nicely with the K3. 73, Dick- K9OM In a message dated 7/10/2011 10:53:16 P.M.

I am not familiar with the various outboard devices to which you refer (as have never needed them). I am not suggesting that the KPA500 needs additional antenna outputs though that is one way to do it. That would constritute an internal antenna switch. The KPA500 represents many upgrades from my 1980's amplifier so I am surprised that my 80's amp has a capability that the KPA500 doesn't. The band data information from the K3 goes to the KPA500 to tell it what band it is to be on. Are you saying this can be paralleled safely and also instruct another device? I would think such might not be compatible and a risky thing to do. In my set up (with an old Yaesu FL-7000) the band data information from the K3 goes to the FL7000 to tell it which band to be on. The FL7000 then associates one of four antenna positions with a band, this is changeable at any time and then remembered, and outputs relay control to a remote antenna switch. If the remote switch is not in use, the "antenna" which is associated by band is irrelevant. I am surprised that the KPA500 does not have this capability standard and built in with the outboard remote antenna relay being an option. Without this, band changing is not, in fact, automatic. ______________________________________________________________ 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
