Ah, but if it doesn't have FCC Type Acceptance, it can NOT be Imported into the USA... Does this radio, that is designed to be used in the USA MILITARY Band, have any type of USA Type Acceptance? It would seem that only the US Military could purchase and operate these units... ....
Although encrypted comms sound like a great capability to have, it is relevant to note that the FCC bans any type of encryption. Alas. David Spero Code Green Prep - Skills and Tools for Life
It turns out that encryption based on public domain coding is permitted. BTPost has researched this in detail. @BTPost
It would be nice to see a link. Not saying that is not correct, but it would be nice to understand the rationale behind the claim.
That relates to a different type of radio use. I am referring to ham radio transmissions, where regulation 97.113 prohibits : The underlining is mine. The one stated exception to the prohibition is for radio control purposes.
It appears that the other radios operating in the ham bands also have the option for encryption. 1 x KIRISUN S780 400-470 MHZ DIGITAL TWO WAY RADIO - 409SHOP LIMITED (HK) Radio Wholesale Here is you tube demo of the S780 about 5:00 in of the encryption.
Not suggesting anyone buy them I just found the interesting. There is some debate here on their codec and use with other digital radios. Brick O'Lore: Kirisun S780: Digital UHF HT
Actually there was a White Paper published by a Communications LawDog, here last year, that makes an Excelent Case, that Encrption on Ameteur Frequencies, when using Digital Emissions, is legal, when the encoding algarythem is logged in the Station Log, along with the message sent in Plain Text. I sent that White Paper to an Old friend, who is now a LawDog with the FCC, to get an UnOfficial opinion, of the validity of the concepts espoused in that White Paper. I received an UnOfficial Reply, that Stated, "that is a very interesting inturpritation of the Rules in Part 97." When you have been With the Commission as long as I had been, and considering the fellow that I queried, Should I have need to send Encrpted Messages, on HF Frequencies, I wouldn't hesitate to do so, using the concepts in the White Paper. But that is just "Me".... YMMV.....
