22 MHz Each channel is a contiguous band of frequencies 22 MHz wide
Television broadcasts on a variety of different frequencies depending on the channel. Each channel occupies an approximately 6 MHz wide band of frequencies. In the US, channel 2 (there is no channel 1) starts at 54 MHz. Channels 3 and 4 follow at 6 MHz intervals (ending at 72 MHz for the top end of channel 4), then there's a gap before channels 5 and 6 in the 76-88 MHz range. There's then a much bigger gap (containing, among other things, FM radio and commercial aviation radio) before channels 7-13 at 174-216 MHz. There's then an even bigger gap before the UHF frequencies (channels 13-51) at 740-698 MHz. The former TV channels 52-83 (698-896 MHz) have been reassigned to other purposes such as cell phones and commercial two-way radio.
1). It has to be an FM radio. 2). For TV sound, tune the radio to 59.75 MHz for Channel 2 65.75 MHz for Channel 3 71.75 MHz for Channel 4 81.75 MHz for Channel 5 87.75 MHz for Channel 6 (can hear this one at the bottom end of your car's FM radio dial) Find the frequencies of other channels on the internet. For each channel, the aural (sound) carrier is 0.25 MHz below the channel's top frequency. Notice that you can't tune most radios to these numbers, because they're designed to receive radio broadcasts, not TV. 3). None of this works at all if the station has gone to all-digital transmission.
