Perhaps it is doable within a single band. Will have to include antenna switching plus sequencer to avoid hot switching. In two band SO2R, the amp would have to switch to another band and adjust the antenna tuner. Perhaps too slow if done over serial CAT. The fact is that KPA1500 was not

Re: [Elecraft] SO2R recommendations

The other problem with DX Doubler, if you operate CW, is that it does not contain an internal keyer. Thus, it doesn't know when you are sending by hand or by computer. If you're sending by hand, you need a monitor. But if you're sending by computer, you may want to listen to the non-transmit radio
