• 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:

I was listening to the Columbus Zoo security channel on my scanner and heard "a report of a signal 12". Does anybody know what a signal 12 is? It sounded like a missing child, but I am not sure (that would be strange because it was an hour after closing time). Also, are there any other known signal codes?

Furthermore, if you have a digital scanner, you can sometimes hear the Zoo/Zoombezi Bay EMS units on Liberty Tac-1 if the fire department has been called on a run. They have a few 800MHz radios and use them to direct the medic to the correct location and to provide the paramedics with advance patient information.

Wow, thanks for all the info! Unfortunately, I do not own a P25-capabale scanner and therefore cannot listen to the COIRS talkgroups.

Thanks 16b (LOL).

I like their Signal 1. There is Dangerous and then there is Seriously Dangerous. I think dangerous would be good enough for me.
If it can harm a human, it's dangerous. If it can eat said human, it's seriously dangerous.
