Having a gap between the highest TV channel number and the lowest FM channel number allowed for expansion, which occurred in 1978 when FM channel 200 (87.9 MHz) was added. [3] FM channel numbers are commonly used for listing FM Station Allotments, which are the FM station assignments designated for individual communities. In the United States ...
The lowest and almost-unused channel, channel 200, extends from 87.8 MHz to 88.0 MHz; thus its center frequency is 87.9 MHz. Channel 201 has a center frequency of 88.1 MHz, and so on, up to channel 300, which extends from 107.8 to 108.0 MHz and has a center frequency of 107.9 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 E4A or channel IC, but at lower volume than wideband FM broadcast stations, because of the lower deviation.
In the United States, the twenty-one channels with center frequencies of 87.9–91.9 MHz (channels 200 through 220) constitute the reserved band, exclusively for non-commercial educational (NCE) stations. The other channels (92.1 MHz through 107.9 MHz (Channels 221–300) may be used by both commercial and non-commercial stations. [3] (Note ...
It had a very small audience and was shut down in 1961 ostensibly to clear the television band: TV channel 5 (102.250 video carrier) if allocated would fall within the VHF FM band (98–108 MHz). The official policy on FM at the time was to eventually introduce it on another band, which would have required FM tuners custom-built for Australia.
The naming convention for FM translators includes their three-digit FM channel number (from 200 to 300), followed by two sequentially assigned letters – for example, K237FR. The translator may identify itself hourly by voice or Morse code. The primary station may instead choose to identify all its translators together; if it does so, the ...
That same year the standard FM broadcasting band was reassigned to 80 channels from 88.1 to 105.9 MHz, which was soon expanded to 100 channels ending at 107.9 MHz (channels 201–300). [11] [12] One additional FM channel, centered on 87.9 MHz (channel 200), was added in 1978. [13]
