Coy, Thanks for the suggestion. I'll give it a try this weekend.

You can use a 20k resistor or so and a 2N3904 or a 2N2222 ( any general purpose NPN transistor. I would sugest building it on a small board such as can be had at Radio Shack. Connect the emitter to A-. Connect one side of the resistor to the base of the transistor and the other end of the resistor to the CAS/RUS. The collector goes to the "COR low input" of the CWID-51B. difference between the CAS and RUS is the CAS goes active (high) anytime the receiver receives anything. the RUS goes active (high) only when the receiver is receiving AND the CG is detecting the proper tone. If you are not using a GE Channel Guard tone decoder then the RUS will track the CAS. I hope this helps. AC0Y Yahoo!
