Hi, thank you for that information. OP25 is able to parse packets that
arrive via the downstream control channel. As an exercise to myself, I
would like to tune my USRP to the *upstream* control channel and see the
various packets being sent to the fixed station. Surely this is
possible without major architectural changes to OP25, correct?
