New project: raspberry pi controlled remote antenna switch. One remote rpi for triggering the 4 relais inside the antenna switch and one rpi connected to the TRX in the shack measuring the ATU port's voltage to fully automatically choose the correct antenna for each band. Let's see how this works out :)

@DL6MHC the raspi 4 has reports of being a noise factory, so maybe keep that in mind if you haven't acquired them yet. cool project, good luck!
