A signal structuring technique that employs direct sequence, frequency hopping or a hybrid of these, which can be used for multiple access and/or multiple functions. This technique decreases the potential interference to other receivers while achieving privacy and increasing the immunity of spread spectrum receivers to noise and interference. Spread spectrum generally makes use of a sequential noise‑like signal structure to spread the normally narrowband information signal over a relatively wide band of frequencies. The receiver correlates the signals to retrieve the original information signal (NTIA)

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

CB radio slang for an illegal amplifier (usally a modified 10/12 meter ham radio amp.) which brings the 4W AM (12W SSB). output to something like 1000 watts or sometimes higher. As a result, the 26.965 to 27.405 MHz band is littered with stations jamming a single channel and not allowing anyone else to use it (AM does not have the "capture effect" that FM does.) because that person is using a "foot warmer" and it congests the frequency so much that it is unusable, and in turn, more people buy "foot warmers" to combat this interferance from distant stations, and thus the cycle continues.
If everyone who used illegal amplifiers was to stop using thier illegal equipment, range and interferance problems would lessen even for those who abandoned thier illegal equipment.

Dude! Hide your foot warmer, here comes uncle charlie!
Roger that, CRYSTAL PALACE BASE CONTROL has a foot warmer.

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.

Short
Wave
Listener
in other words, a radio operator who listens to short wave radio transmissions and spends all of his time hunched in front of a 5000 dollar radio, is usally a cracker and a loser
