I have a BCD436HP and I can't receive any talk groups with a mode of T (TDMA). I have scanned all sites including 3-3. I receive everything else except TDMA groups. Example is the Pasadena Fire Department. Any ideas what I may have done or need to do? TIA Also this applies to Houston, Deer Park as well.

Hi & welcome!
Is this the trunked system you're trying to monitor by chance? If so, there are a number of simulcast cells on that system. Have a read about simulcast distortion here, it's one of the most discussed topics/issues on these forums. There are a number of workarounds suggested in that article, but they work in very few instances. I'd recommend selling the 436HP and putting the funds towards an SDS100 for a better decode on these types of systems. Trust me, the improvement is like night and day
