Why do radio and TV stations start with W?
All radio stations have a four-letter identification code. The letters ‘N’ and ‘A’ were given to military stations, but ‘K’ and ‘W’ were assigned out for commercial use. Radio stations east of the Mississippi River had to start their stations with ‘W’, and stations west of the Mississippi with ‘K’.
What is the difference between a channel and a station?
A given station could provide the same (or different) content over more than one channel. Channel refers to a particular numerical place on the “dial”. At one time, this was a specific frequency over the VHF or UHF spectrum, such as channel 2 (VHF) or channel 83 (UHF).
How does a TV channel work?
When the band of frequencies in the picture signal is imposed on the high-frequency broadcast carrier current in the modulator of the transmitter, two bands of frequencies are produced above and below the carrier frequency. These are known as the upper and lower side bands, respectively.

Radio stations use frequencies, not channels–88.5 FM, 1550 AM, 16.7 MhZ, etc. — while TV stations use a number that has a particular position on the old tuner dial. So it is not that one uses “station” and one uses “channel.” A broadcasting station uses a particular frequency on radio and a channel on TV.
Why don’t AM radio stations have channel numbers?
AM radio is the exception in that it never has used channel numbers. Well, it’s just terminology relevant to the industry. They’re called radio stations because operate on their own frequency, either through amplitude modulation and frequency modulation.
