• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

HP-1: Mixed TDMA/FDMA talkgroup support

Let me get this right out of the way first:

I understand the HP-1 is not able to listen to TDMA talkgroups.

If unlistenable modulation formats such as NXDN, D-Star and talkgroups marked Encrypted are imported, I don't understand why TDMA talkgroups aren't imported?

There's a system near me that supports mixed mode (TDMA/FDMA) talkgroups. I noticed that HomePatrol Sentinel does not import any talkgroups marked as TDMA in the RadioReference Database.

Since these talkgroups flip back and forth between TDMA and FDMA depending on the capabilities that the radios that are affiliated to them have, why are they excluded from Sentinel?

I'll have to create a favourites list and enter them all in by hand for now unless Uniden updates the process that is filtering them out.
