I had to go back to my URI interface and my FT-736R. I have it set up to do tone encode and decode using the URI. All the encode and decode are working however when I unkey there is a squelch tail that lasts about 1 to 2 seconds. I'm allowing the URI to determine COR thru DSP. The connections are setup for raw audio both ways with the node supplying the pre and de emphasis. I have played with the settings but nothing changes the problem. It isn't a consistent duration of tail. I know it is in tone decode mode because if I turn tone off on the portable I can't open the squelch thru the node. Anyone have any ideas......
