[App_rpt-users] Long Squelch tail problem

[Bill Hurlock]

I have tried tightening the SQ but then I start to have decode issues with some of the connecting radios. The current signal strength reading, no carrier present, is 776 and SQ setting is 900. This does eliminate the SQ tail but I'm sure this is going to affect RX sensitivity over all being so high. There appears to be a very narrow range of SQ levels that provide no SQ tail and decode is fair. Most problematic are the Wouxon radios.

Have you tried increasing the squelch level?  What is the current squelch level?

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......
