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.
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 ...
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 ...
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.
Land mobile use of a TV channel (TV RF channels 14-20 only) LM As "LM" is used in the FCC database to indicate reallocation of an entire channel, but not to identify individual users transmitting in that spectrum, a 6 MHz LM allocation does not itself carry a TV-style call sign. The spectrum of TV channels 14-20 is called "T-band" in LMR use. [17]

FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave. Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to transmit high-fidelity sound over broadcast radio. [1]
