Long Haul HF

HF can link the continent together so you know what is happening all the way across the continent, even to the other end of the continent. It beats restricting yourself to only knowing what's going on 20, 40 or 60 miles away.(Not to mention talking worldwide or just listening worldwide, Hmmm?). Check out this article on the Regency Net and GRC-215s radios to get an idea of how the government planned to use HF to provide trans and post attack communications among nuclear capable units in the European Theater and then applied the concept for use in Continental United States (CONUS) for Federal Emergency Management Agency. (FEMA). (A U.S. Federal government agency) The acronym is also jokingly defined as "Foolishly Expecting Meaningful Aid."

Business band

The business band is the name used by US scanner hobbyists who listen to Federal Communications Commission licensees using Industrial/Business poolfrequencies. The regulations listing frequencies in this pool are contained in Subpart C of Part 90, Title 47 of the CFR.

The pool describes a series of frequencies on the VHF and UHF two-way radio bands. They are reserved for use by businesses, and in some cases, by individuals. In the United States, private use of these frequencies requires a federal license issued by the U.S. FCC. The exceptions to this are five specific frequencies that are also part of the Multi-Use Radio Service, which permits unlicensed operation on these frequencies, provided the output power does not exceed 2 watts.

The electromagnetic spectrum between approximately 450 and 470 MHz is used largely for UHF business communications, although this spectrum is not exclusively for business use. In some large metropolitan areas, such as New York, the UHF-T band (between 470 and 512 MHz) is also used, due to congestion on the standard VHF or UHF bands. There are also a number of specific frequencies, in both the VHF and UHF spectrum, that are for business use; some of these have color-coded names, such as Blue Dot or Red Star.
