    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've used Goldwave to record scanner audio. Get the tones then play them back thru Goldwave and you can get the freqs that way. I forget the exact steps needed since it's been a while but it can be done.

If you want a program to decode the tones, use the comtekk one. But if you just want to know what the specific frequencies are, just let me know. I've got lists of them for a bunch of NJ counties.

The audible tones that are used to activate some fire and EMS pagers (among other things). Many of them are motorola quick call II (also shortened as QCII).

Some of the newer high-end uniden scanners can be programmed with these to keep a channel silent until you hear a set of tomes you want, like for listening to just one stations dispatches. Lots of commercial two way radios can do that as well, some can also send the tones too.
