<---I'm surprised your controller doesn't recognize .5 volts as a logic low. Actually the chances of finding a point in the receiver that drops to exactly zero is pretty slim, as a bipolar transistor which is full saturated, will still have a .6 volt drop across it. What you could try is a pull down resistor (from the COS wire connected to the controller to ground) and see if you can pull the low level down enough for the controller to recognize. You might start with a 10K and work your way down. Of course if the squelch in the radio stops working, you've probably gone too low a value :-) Ken ------------------------------------------------------------------------------ President and CTO - Arcom Communications Makers of state-of-the-art repeater controllers and accessories. http://www.ah6le.net/arcom/index.html AH6LE/R - IRLP Node 3000 http://www.irlp.net Yahoo!
