Jim,. I use the "1A2R" (one amp tw0 radios) from 4O4A. I have two rigs share my KPA1500. However, if the rigs are on different bands, you do need to rely on frequency sensing by the amp. Not sure if the KPA500 does that.

I was hoping to (easily) be able to use the amp with either rig while both were here in the shack. Pulling the audio cable when I want to use the IC-705 with the amp isn’t practical due to the location of the radio. I changed the “Radio” setting from K3 to Analog and Serial, but with the cables attached, the result is the same - as soon as the amp is put in OPER mode it goes into transmit state (* showing on the LCD). So, the only option for the time being is to always have the K3 powered up and on the band that I want to operate the IC-705 on. Just need to keep their frequencies separated as much as I can. Unless Jack comes up with an alternate…! :-) :-) Jim / K7TXA ______________________________________________________________ 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 w...@arrl.net
