SOS

SOS really doesn't stand for anything, as any radio operator will tell you,

it is simply "SOS" becuase the letters S and O are very easy to understand under conditions of high interferance.

so stop saying "Save our whatever"
SOS, SOS, Titanic

losing my religion

it literally means "losing my temper" or "going insane" to some degree. If you would look at the REM lyrics to the song by the same name, it makes more sense, it really has nothing to do with religion.
I was pretty much losing my religion after being forced to listen to rap music by all the freshman girls at my school.

pirate radio

Pirate radio stations are usally one or two-person operations airing home-brew entertainment and/or iconoclastic viewpoints. In order to avoid detection by the authorites (The Man, FCC, etc), they tend to appear irregularly, with little concern for the niceties of conventional program scheduling. Most are found in Europe chiefly on weekends and major holidays, and mainly during the evenings in North America, often just above 6200.0 kHz, just below 7000.0 kHz (6955 and 6995 kHz are common pirate frequencies) and just above 7345 kHz. These sub rosa stations and thier addresses are subject to unusally abrupt change or termination, as well as their frequency of transmission, to avoid being cought by the FCC.
Free Radio stations are unlicensed broadcasters. They operate in defiance of FCC rules, which often seem to be more concerned with protecting the big broadcasting interests.

freeband

The term "freeband" pretty much refers to the 25.1000 MHz (25100.0 kHz) to 28.0000 MHz (28000.0 kHz) band, although people do operate "freeband" above those ranges, and into the 10-meter ham radio band (which is REALLY illegal). Freeband comes from the 26.9650 to 27.4050 MHz CB radio band. Because of heavy use of this band al around the world (in all modes, AM, SSB, FM). People started to modify thier CB radios to operate above or below (usally above, in the 27.4150 to 28.775 MHz range) the normal CB band. Really, this band has very little users, the military and government have a few channels, and 28.000 to 29.700 is ham radio, and there are a few channels allocated to the Forest Products Radio Service/Business Radio Pool.

The most common modulation mode is SSB.

The international calling frequency is 27.555 MHz (27555.0 kHz)
The DX-949 is a common freeband radio.

Radio Scanner

a radio receiver that can quickly switch between two or more channels (today's scanners usally have more then 500 channels) and then stop when the frequency is active. Used by criminals and radio operators to listent to pretty much everything from the police officer asking his buddy to get him more doughnuts and your cordless phone.
