The key benefit of satellite radios over standard FM radio is the clarity of sound. There is also the possibility of obtaining more stations via satellite than normal radio.
The AM/FM/CD/etc. radios are the same as found in cars.
AM - Amplitude Modulation FM - Frequency Modulation
There are many types of emergency radios available. Some of the types of radio available include Ham radio, AM radios, FM radios, CB radios and walkie talkies.

They could if they wanted to. But if they have military-type information to swap, thenthey really have no desire to do it in the FM commercial broadcast band at frequenciesbetween 88 and 108 MHz, where household radios are equipped to receive.

"FM" refers to the means by which information is impressed on an RF carrier wave. The form in which the information is coded or packaged doesn't matter. FM commercial broadcasting between 88 and 108 MHz stil packages the information in analog form. Although the technology to do it digitally is reliable and well developed, any wholesale switch ... like what happened with digital TV ... would leave possibly as many as a quarter-billion FM radios out in the cold. So any switchover to digital FM is sure to be a gradual process.
The FM radio was invented in 1933. It was invented by the inventor Edwin Howard Armstrong. He invented the frequency that allows radios to work.
