• 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:

PRO-197 won't recognize talk groups

One of my PRO-197s has been working fine for over 3 years on a P-25 digital trunked system. I have police, fire and sheriff talk groups programed. There are about 20 others (jail, courts, animal control, public works, etc) that I don't have programmed. Several days ago the scanner went silent. It still shows it is scanning and when I analyze the control channel it looks good, strong signal, decoding 82-99%.

For a test I programmed all the voice channels as conventional channels. I can now hear all transmission made on any of the voice channels.

I did all the resets and reloaded my profile. No change. Restoring everything to factory settings made no difference. Then I undated the firmware to the latest release. No change.

It appears that everything is OK except it will not recognize any of the talk group codes. Any ideas?

This probably is not the problem, but maybe the TRS administrators changed the control-channel?

Just a thought,
