What is the W in radio station call letters?

What do AM and FM stand for?
AM and FM modulated signals for radio. AM (Amplitude Modulation) and FM (Frequency Modulation) are types of modulation (coding). The electrical signal from program material, usually coming from a studio, is mixed with a carrier wave of a specific frequency, then broadcast.
Why do American radio stations have weird names?
You use callsigns. They’re especially important for two-way communication but commercial broadcast stations are still assigned them by the FCC and are required to announce them at the top of each hour. This is the only good explanation of the “weird” station names.

Which is better AM or FM?
FM is less prone to interference than AM. However, FM signals are impacted by physical barriers. FM has better sound quality due to higher bandwidth. … In AM radio broadcasting, the modulating signal has bandwidth of 15kHz, and hence the bandwidth of an amplitude-modulated signal is 30kHz.
Why is AM radio reception so bad?
If the battery operated radio reception is good, interference could be caused by the mains power – check the power cord is well insulated. If both radios are affected, the problem is likely to be electrical interference to the antenna, caused by a nearby electrical appliance.
What is difference between AM and FM?
The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
Why do radio stations use K and 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.
