I am just wondering if anyone knows how to decode simple voice inversion with audio software from the net. You know the donald duck sound u here. As far as I can tell its voice inversion, not rolling code inversion. ITs analog

If you live in the U.S., it is illegal to decrypt inverted speech scambling on radio communications.

So if you have an FRS radio with voice inversion and someone else is using voice inversion on another FRS radio and you happen to be on the same channel is it illegal to "decode" his communications ?

Yes, unless the transmissions are directed at you.

I'm not sure voice inversion (or any encryption) is legal to transmit on FRS, though.

Voice inversion is NOT ecnryption, It simply scrambles your voice, Depending on the kind of inversion (There are different kinds) a simple ramsey kit can de-scramble it, Where as encryption is MUCH HARDER to crack, I'm not even sure if encryption is possible to crack, I'm not that advanced yet.

Unknown what method of encryption they are using...

Dave,

Encryption is legal on Family Radio Service frequencies. Note on the Commission's website about the service
http://wireless.fcc.gov/services/index.htm?job=service_home&id=family that the only expressly prohibited actions are a) making telephone calls using FRS frequencies (see first paragraph), and b) modifying certified equipment (see paragraph under caption "Licensing"). An example of a certified FRS radio that is scramble capable would be the Cobra FRS310WX (see page 36 of the owners manual at http://www.cobra.com/pdf/CBs/310WX.pdf ).

Title 18 of the law passed by congress states it is illegal to listen to radio communications unelss:
16) “readily accessible to the general public” means, with respect to a radio communication, that such communication is not—
(A) scrambled or encrypted;

Congress saw no distinction between the two........

scramble vb.
9. (tr.) to render (speech) unintelligible during transmission by means of an electronic scrambler.

encrypt vb. (tr.)
3. to distort (a television or other signal) so that it cannot be understood without the appropriate decryption equipment.

Pretty much the same thing eh? Never mind the "laws are meant to be broken" thing, use your own judgment and keep quiet if you do. Your tongue makes a nice shovel for digging your own grave and many useless threads are started this way.

What about descrambling or decrypting my OWN radio transmissions? (i.e., can I legally monitor myself?)

My take on scrambling vs. encryption on FRS according to the above definitions is scrambling is legal on FRS but encryption is not.

Scrambling example: Analog audio inversion.
Encryption example: Analog or digital DES

ramsey kits

the ramsey kits I had worked just fine, the older one was better because of the way it was powered up, its been many years since I moved from southern bergen county and had to use them.

Regarding scrambling and/or encryption on FRS, ECPA'86 also prohibits monitoring radio communications which use a system where "essential modulation parameters have been withheld from the public."

That's clearly not the case with FRS since no essential modulation parameters have been withheld from the public. IOW, there's nothing secret about the particular modulation type (FM) being used on FRS while audio inversion scrambling is in progress. The modulation type is still analog narrowband FM.

ECPA's prohibition on cracking "essential modulation parameters" applies to proprietary formats like iDEN. It is unlawful to decode these specific kinds of transmission.

The section about "scrambled or encryption" covers a separate issue. Even if the modulation parameters and the type of encryption are known, ECPA still forbids the general public to decrypt any radio transmissions.

Common sense dictates that if you are originating an encrypted transmission or if such is directed to you as the intended recipient, then you are not "the general public" with respect to that communication.

Every word in a statute has a purpose, and the division of a statute into paragraphs and sections means something. You can't just jumble up the law any way you want to get it to say what you wish were true, or to read ridiculous interpretations into it. In fact, there are standardized rules for legal construction that guide lawmakers and judges and should guide anyone who wants to know what the law means. For federal laws, consult the 2nd edition of American Jurisprudence (Am. Jur. 2d).
