I already changed SA.exe and Arduino SW to allow selecting which SI4432 is used for signal strength measurement. Only need to test
You can indeed also put a HW switch on the nSel line, but both SI4432 are initialized at startup so you have to make sure both are there.
For me keeping the PC based control SW generic is important. I'm now using SA.exe for 2 different SA's
My updated TAPR-VNA SW can control 3 different VNA's. Really saves a lot of work
