would you be able to transmit under the noisefloor and integrate on the other side? i imagine it would still break the law, but you wouldn't be likely to get caught?
Physics aside, I think the FCC is very, very slowly considering removing the "no encryption" aspect of ham radio. The arguments against encryption seem to be weak, and revolve around "if we don't know what people are saying, we won't know if they're trying to use it for commercial purposes" which is just simply not true. Oh well, here's to hoping the FCC will move into this century!
Under the noise floor at what distance? If you don't want to be a bright beacon at a mile, then you're not going to have a lot of signal at a hundred miles.
In Part 95, Section D, encryption is not mentioned.
But the Emission Types are limited, digital emissions are not allowed. (AM and SSB) are specified.)
In theory, you could have a transmission header / trailer in Esperanto that would route the message, and then the message traffic. But that sounds like a hill that wouldn't be worth the climb.
Indeed, only plain language voice communications are allowed.
§ 95.931 Permissible CBRS uses.
The operator of a CBRS station may use that station to transmit two-way plain language voice communications to other CBRS stations and to other stations that are authorized to transmit on CBRS frequencies.
