Ok this flashing S is beginning to tick me off. i know you should be seeing a flashing T when scanning and on an active channel but all i see is the flashing S with a occasional T but its mostly the S that keeps flashing. i know it has to do with squelch but i turn up squelch and its still there flashing and now its interfering with my reception. signal now bounces all over the place and radio has hard time receiving. i had the pro 668 and that didnt have the S on it at all. signal will be solid with solid T then signal disappears and bounces all over with flashing S. can this S be disabled? please any help would be great.thanks. oh by the way im monitoring starcom p25 simulcast 700 MHZ system and a WS1080 scanner.
