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.

If you operate 2BSIQ it really pushes the amp duty cycle, especially on RTTY. The Flex amp is already set up for this.

Seems like a great solution for my Flex6600M and KPA1500 combo.
