• 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:

Hey guys, I'm in Houston for a couple of days and trying to listen to Houston Fire/EMS. I have my PRO 668 with me and thought that I had it programmed correctly; however, I'm not hearing much. I have my conventional scanner set to the uhf station alerting frequency (460.575) and hear that fine, but my PRO 668 when set to the same channel on the TxWARN system only catches the transmission about 10% of the time. Any ideas on what I'm doing wrong? I'm listening from Northwest Houston.

I believe you'll need a TDMA-capable scanner. Also, most of the fire talk groups are encrypted.

Check out this article if you haven't. It was very helpful to me. There is a way to hear phase I or II transmissions (and you should be able to hear both), depending on which site you are monitoring. If you have the Phase II talk groups programmed in but your radio is on site 3-05, I don't think you'll hear anything. But if you are hearing some, could be simulcast problems, unless the 668 is switching between sites occasionally.

You're not doing anything wrong. That is just the nature of how those scanners perform on simulcast P25 trunking systems.

Ideally you should program any Houston city sites (identified as RFSS 3) and talkgroups (any above 30000) as a seperate system from the rest of TxWARN. Since you're on the northwest side and have a TDMA-capable scanner you can load up the Northwest Simulcast (03-002) and 40050 for responses in your area. As previously stated the tacs are encrypted so you can't hear working incidents or fireground comms.
