I have derived a COR from a handheld by placing the diode of an opto-isolator in series with the receive LED and using the transistor in the opto-isolator for the COR.? You can get a negative going signal by connecting the emitter to ground and having the collector go negative, or put the collector to a positive voltage and having the emitter go positive for the COR signal.
