Well i tried everything under the sun but i cannot get this thing (bcd436hp) to stop missing the first second of transmissions on a p25 phase1 trunked system. i thought i had it figured out but it was doing it again. im tired of only hearing 4 and not 10-4. not only that it wont stay on the system i want to hold on. and the mystery talk ids that are on the radio but no where to be found in sentinel which are encrypted and sound like a rat trying to chew his way out of the radio. i hit avoid button twice to avoid it all together and it only says temp avoid. sorry for my rambling but its sad to have to send this scanner back.other than these issues i really like the scanner.
