    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:

How do I find out the encode/decode tones?

Are there scanners out there or other ways of scanning local frequencies and which display the encode/decode tones that are going to and from the repeaters? I hope this question makes sense.......

If your talkin repeater access tones then I beleive you would need a DTMF decoder. If your talking ANI PTT ID or emergency, there are aftermarket ANI decoders out there that connect to an audio output from a 2 way or scanner. And I guess lastly if its just PL/DPL subaudible tones you want there are uniden and RS scanners out there that will do auto decode and display. Hope this helps... Chris

If you are less inclined to buy a piece of hardware just for this there's always the software solution. This site has several different pieces of software you can try:

Anything that references PL or CTCSS tones should do what you are wanting. There are also DTMF decoders and many other signal types that can be decoded.

Basically you get a double ended male head-phone jack and connect the scanner to your pc soundcard. Some types of signals can't be decoded without a "discriminator tap" which gives you a better signal out of the scanner. However an audible tone like CTCSS shouldn't require this.

I think he's just looking for the ctcss tones used. Most newer model scanners will figure out the tone and display it for you.

There are also add on external boxes which do the same thing.
