Re: [Elecraft] KPA1500 AND THE 403A 1A2R
I don’t specifically use the 4O3A switch, but I do have single amp SO2R using a KPA1500 and two K3s. I’m using a MK2R to generate the band data with a set of 4 TopTen A-B switches to handle the RF switching. An Arduino handles the AuxBus messages between the amp and the radios. The amp does make a bit of fan noise on RTTY when dual CQing, but otherwise works just fine. I have the amp in a closet so the noise is not a concern.

Re: [Elecraft] KPA1500 AND THE 403A 1A2R
Excellent point on the band data issue John. I was holding out for the Flex amp but no tuner is an issue for me with my low band antennas. If they ever put the tuner in the amp I will consider it. Will have to study the band data issue.
