[NHRC-user] Wimpy, echo'y ID audio, no bass

[Jeff Otterson]

The receiver input to the NHRC-5 is about 10K ohms impedance.

That would be a good place to start.

Otherwise,  you could conceivable wire in to pin 3 of the DAD 
connector.  You need to have a 1/2 Vcc DC bias here, though.  Might be more 
trouble than it's worth.
