Using sdr_transceiver_hpsdr. It looks like band switching controls the pins on the extension socket E1 of the RP pcb via a status register (sts) in the C source file. Is there a spec of the E1 pin usage please.

Yes but I'd forgotten where it was, quite the obvious place. Is the communication controlled via the sts register in the C file?

pins DIO0_N - DIO3_N are connected to the sts register. pins DIO0_P - DIO7_P are connected to the cfg register.
