System similar to what you mentioned regarding the gain 
compensation/distribution, HPF/BPFs, RX overload, PTT, and 
additional signal path sources and output routing (incl. looping 
back): http://no3m.net/index.php?page=signal-processor

Has an on-board embedded MPU, but a header can be used w/ 
switches for manual control.

> If it were the 'ideal' thing, there'd be a box with a matrix of switches (A x B), gain blocks that could be put in/out of the circuit, BPFs that could be put in and out, 'muting' of any RX output that is connected to a transmitter that is transmitting, RX overload protection, and some general purpose inputs to select the 'configuration'. Probably a PIC to run it, with a nice GUI app to configure it.
