Encryption on CH68?

[DDan]

Is encryption legal on CH68? I've googled and searched this forum and didn't find anything relevant.

Do you mean encryption or scrambling? There shouldn't be any on us marine channels,but then in the real world why not?

You are correct, it is really scrambling. I didn't think it was legal but I failed to find proof on the net.

scrambling = encryption

The answer would be in Part 80 of the FCC Regulations.

I've heard the basic Speech inversion and the rolling-code inversion for years here in New England.

Yes they are legal, ICOM makes marine radios with built-in voice scramblers. One such radio, IC-M72 has a built in 32 code scrambler. I am guessing it would be split band scrambling since their are 32 possible split points for split band scrambling. They also make fixed inversion and hopping split band scramblers that can be put in marine radios.

No it's not encryption, it's scrambling & it's legal on the VHF marine band, This was covered 14 post earlier on 07/07/09 on this forum. I have a Uniden UM525, an ICOM M604 & a Standard Horizon GX3500S which all have scrambling capability available as an option. If you have a West Marine store near you & the sales associates are friendly & if they have a couple of radios with the scrambling upgrade, they will show you how it works. I opted out of that as an option, not worth the money & not enough mariners to use it with anyway. In Florida a lot of Fleet ships & fishermen use that capabilty to communicate with one another mostly to keep the good fishing spots amongts themselves, then of course the inland hunters & druggies have caught on to this end user available technology & are milking it for all it's worth, so much for ruining a good thing.

Scrambling is a primitive form of encryption. Legally they are the same.
