A signal strucÂturing techÂnique that employs direct seÂquence, frequency hopping or a hybrid of these, which can be used for multiple access and/or multiple funcÂtions. This technique decreases the potential interferÂence to other receivers while achieving privacy and increasing the immunity of spread specÂtrum receivers to noise and interference. Spread specÂtrum generally makes use of a sequential noiseÂ‑like signal structure to spread the normally narrowÂband informaÂtion signal over a relatively wide band of frequencies. The receiver correÂlates the signals to retrieve the origiÂnal informaÂtion signal (NTIA)
Normal scanners cannot get spread spectrum transmissions.

Pretty good program, considering its made by microsoft. Although its really bad about slowing my computer down (it is an HP, which sucks)
Running, Call of Duty, AIM, Norton Antivirus and listening to my Smashing Pumpkins CD on Windows Media Player....computer actully slows down....thank you Windows XP

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.

Automatic Direction Finder
or
Automatic Direction Finding System
a navagation system used by aircraft and sea-going ships. It consists of one or more ground stations that transmit a signal in the 225 to 500 kHz (.225 to .500 MHz) range. Because of the low-frequnecy of these signals, their range is very good and not limited by the line-of-sight range of the VOR system. The recevier in the airplane/boat uses a loop antenna to "home-in" on the station. There is also a long-wire receiving antenna installed on many aircraft. Most ADF receivers can also recieve the AM broadcast band (530 to 1710 kHz) so pilots can also home in on powerful broadcast stations.
ADF signals should not be used in thunderstorms because the high amount of electro-magnetic interferance that lightening causes.
Many pilots can't even use the ADF system, which is a shame, becuase of better systems such as VOR and the GPS systems.
"In most of the third world, the ADF navigation system is the only way to go"

USAF radio code for command post or any other station that somewhat has command over something. Not used in UHF communications band. It is mostly the VHF tactical communications band (30 to 50 MHz)

An English company formed in 1600 to develop trade with the new British colonies in India and southeastern Asia; in the 18th century it assumed administrative control of Bengal and held it until the British army took over in 1858 after the Indian Mutiny
I have no idea why I am putting this definition in here, after all, its an urbandictionary, and this is history.

Top 40
a FM radio format that usally plays music thats the top 40 on the charts, they may play music that is (sarcastic gasp) more then 2 years old!!!!
GET WITH THE PICTURE PEOPLE...
Top 40 stations suck, most of the good music is older, and is rock/alternative rock.
"I hate Top 40 stations"
