The Pan-American television frequencies are different for terrestrial and cable television systems. Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 36 and occupies frequencies between 470 and 608 MHz.
FM channel 200, 87.9 MHz, overlaps TV 6. This is used only by K200AA.; TV 6 analog audio can be heard on FM 87.75 on most broadcast radio receivers as well as on a European TV tuned to channel 4A or channel C, but at lower volume than wideband FM broadcast stations, because of the lower deviation.
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 centred ...
American Broadcasting Company (ABC) – The nation's third-largest commercial network, ABC was originally formed from the NBC Blue Network (1927–1945), a radio network which the Federal Communications Commission (FCC) forced NBC (National Broadcasting Company) to sell in 1943 for anti-monopoly reasons, the ABC-TV network began broadcasting in 1948.
The station has used various virtual channels since its conversion to digital television in 2012, due to the lack of allocations in the New York and Philadelphia markets, starting on channel 3 (conflicting with KYW-TV), then 51 (averting a conflict with NJ PBS station WNJN on channel 50) from late 2013 until mid-2019, then 6 and 18 (conflicting ...
Because the antenna size is based on the wavelength, UHF broadcasting can be received with much smaller antennas than VHF while still having the same gain. For instance, Channel 2 in the North American television frequencies is at 54 MHz, which corresponds to a wavelength of 5.5 m, and thus requires dipole antenna about 2.75 m across. In ...
TETRA uses different channel spacing compared to GSM systems. The standard is 25 kHz spacing and the center frequency of each channel may be offset in a number of fashions such as ±12.5 kHz or even ±6.25 kHz. This makes it more tricky to correlate the ARFCN strictly to a pair of frequencies, you need to know the specifics of the system.
