I'm not aware of any HF bands you can use in the US without a license. And it is prohibited to use any kind of secret encryption on amateur bands.

11 meters is in a different part than ham and is usable unlicensed.

Doesn't mean you can send encrypted traffic and there are FCC rules about duty cycle, etc.

[AstroJetson]

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.
