I have a 436HP, 536HP and just got a SDS100 scanner and all work fine with our local P25 system ( Rockingham / Harrisonburg, VA). A coworker just bought a new BCD436HP and asked if I would program it with the exact same favorite lists as are in mine, I did and everything works except that system and I've done scanners for 2 other friends the same way and they worked. This scanner will never stop on that system and if I manually hold it on one of the P25 TGID's it will only get about 1 out of 25 transmissions if that. Any ideas on this ? I've tried clearing user data and starting from scratch but still the same result every time.
