If they are on VHF still then yes, they use a inversion scrambler. You'd need to buy a descrambler. I used to see them sold in a mag called Nuts and Volts. Im not sure if they make that mag anymore?? Maybe someone else knows.

If they're encrypted, then no...there is no way to demodulate the signal and there never will be (at least not legally).

If it sounds like listening on the wrong sideband, then its inversion scrambling. speech inversion might be a good noise-toy for CB, talk to your buddy privately and **Censored**-off everybody else.

If it sounds like FM squelch-open background noise, then its AES or DES encrypted.

AES is impossible to decrypt unless your the NSA.
DES is possible to decrypt with modern computers. Maybe some of the folks on radioreference dot com have brute-forced an over-the-air DES key.

Yep, several years ago, before cordless phones moved up to 2.4GHz and higher, they started using speech inversion as a means to keep people with scanners from listening in on conversations. Of course, those of us that had the right equipment and spent enough time on it, could make it intelligible enough to get the gist of the conversation.

You like CBs, you play in a rock band. If it wasn't for your picture and the fact that you crochet, we'd think you were one of the guys.

I grew up with brothers...lol...Between my dad and my brothers, all I did was geeky science stuff and play music. My older brother bought me my first guitar and let me be in his band when I was 15....heh. Now, the crochet I got from my grandmother....

Annie :)
