The ELT transmits a distincive signal on the international emergency frequencies of 121.5 MHz (VHF) and 243.0 MHz (UHF). This signal is picked up by ground stations, search and resuce aircraft (see Civil Air Patrol and Coast Guard, and satelites. Direction-finding equipment is then used to "home-in" on the signal and locate the downed aircraft.

Spybot - Search & Destroy

An excellent program which removes Spyware, Adware, daillers and many other malacious programs and files on your computer. It can also fix registry problems and remove usage tracks from your registry. It is a free download as are the update files (same with Ad-Aware, another great program).

I use both Ad-Aware and Spybot - Search & Destroy on my computer to remove spyware and other bad programs.

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.

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
