I am interested in EMCOMM support for both private and public entities. However, I am puzzled by how to use Vara HF for the services using Private Land Mobile here in the US. That service is regulated by the FCC Part 90 regulations, and my reading of that section seems to indicate it allows SSB operation below 25 MHz for only voice, (J3E) not any data modes (J3D). Also, since the Vara package now capable of encryption is Vara HF, what equipment would one use for operation on PLM frequencies? It would need to be certified to Part 90 standards, I believe. Also, it seems the operation of a base station would require careful coordination with controlling agencies, as frequency assignments are based on limiting coverage to a limited geographical area so as to not create interference with other licensees using the same frequency in other areas. How would one go about getting all these conditions satisfied?
