Channel 37
Channel 37 is an intentionally unused ultra-high frequency (UHF) television broadcasting channel by countries in most of ITU region 2 such as the United States, Canada, Mexico and Brazil. The frequency range allocated to this channel is important for radio astronomy, so all broadcasting is prohibited within a window of frequencies centered typically on 611 MHz. Similar reservations exist in portions of the Eurasian and Asian regions, although the channel numbering varies.
Channel 37 in System M and N countries occupied a band of UHF frequencies from 608 to 614 MHz. This band is particularly important to radio astronomy because it allows observation in a region of the spectrum in between the dedicated frequency allocations near 410 MHz and 1.4 GHz. The area reserved or unused differs from nation to nation and region to region (as for example the EU and British Isles have slightly different reserved frequency areas).
One radio astronomy application in this band is for very-long-baseline interferometry.
When UHF channels were being allocated in the United States in 1952, channel 37 was assigned to 18 communities across the country. One of them, Valdosta, Georgia, featured the only construction permit ever issued for channel 37: WGOV-TV, owned by Eurith Dickenson "Dee" Rivers Jr., son of the former governor of Georgia (hence the call letters). Rivers received the CP on February 26, 1953, but WGOV-TV never made it to the air; on October 28, 1955, they requested an allocation on channel 8, but the petition was denied.
In 1963, the Federal Communications Commission (FCC) adopted a 10-year moratorium on any allocation of stations to Channel 37. A new ban on such stations took effect at the beginning of 1974, and was made permanent by a number of later FCC actions. As a result of this, and similar actions by the Canadian Radio-television and Telecommunications Commission, Channel 37 has never been used by any over-the-air television station in Canada or the United States.
The 2016–2021 repack left no North American stations above UHF 36.
The low-power WNWT-LD in New York was given virtual channel 37 in August 2019, thus becoming the first American station to be so assigned via the digital television PSIP standard. While the channel is displayed as "37.1" or "37-1" on a digital television set, WNWT-LD's physical signal remains on VHF channel 3, causing no interference.
Reservations and use outside the US have a non-exclusive legal status
