Re: Encrypted Radios

I use to have analog private channel tranceivers that used binded modulation to hide modulated audio.;P

As far as encrypted modern RF goes alot of people mistake encoding with encryption. Like the supposed secure 2.8Ghz-5.8Ghz cordless phones you buy at department stores.

There's a wide array of differences between standards in encoding, and cryptography. Of course most of you are "experts," so I'll not bother you with any more of my "little people" information.

Re: Encrypted Radios

I meant radio signals (frequencies) commonly used for long distance voice communication, like HAM, which is not permitted to encrypt data (per FCC).

Re: Encrypted Radios

I am not sure about your local laws, but in many countries, like UK, encrypting radio signals is illegal and therefore ability to purchase equipment may be very limited.

There must be exceptions to this, otherwise, where are things like WEP, WPA and WPA2, or ssh tunnels over wireless used to carry VoIP might be problematic.

Also, if it is just encryption, perhaps Spread Spectrum techniques would be permitted.

I can see issues with erosion of these kind of laws, as digial encoding of analog data (voice or sound sources) could be classified as a kind of encryption, since a digital decoder is needed.

Another idea? Pre-shared static signals kept secret and retransmitted with differences used to pass the real data. ( One time pad, XOR with keysize-data length, "vernam cipher" meets steganography with respect to radio frequency static ) Yay! Putting needles in haystacks.

Re: Encrypted Radios

Hi, I've become interested in encrypted walkie talkies and full radio sets that offer encryption, but I don't really know what brands are good or which models are?

Which ones do you guys like?

To the best of my knowledge, all the major manufacturers (i.e., Motorola, Kenwood, ICOM, Yaesu) offer radios with encryption capabilities. Not sure about their availability, though.
