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.
