worst hour of the year

That hour of the year during which the median noise over any radio path is at a maximum.
Note: This hour is considered to coincide with the hour during which the greatest transmission loss occurs.

GSM

Global System for Mobile communications.

The most common digital cellular system in the world. GSM is used all over Europe, plus many countries in the Middle East, Asia, Africa, South America, Australia, and North America. GSM's air interface is based on narrowband TDMA technology, where available frequency bands are divided into time slots, with each user having access to one time slot at regular intervals. Narrow band TDMA allows eight simultaneous communications on a single radio multiplexor and is designed to support 16 half-rate channels. GSM also is the only technology that provides incoming and outgoing data services, such as email, fax, and internet surfing. GSM makes use of a SIM card that allows memory portability between dumb GSM phones.
The GSM system allowed for both internet surfing and digital voice communications over 1900 MHz radio networks.

repeater

1) A device that receives, amplifies (and sometimes reshapes), and retransmits a signal. It is used to boost signal levels and extend the distance a signal can be transmitted. In radio terms, the signal is usally recieved on a input frequency and then retransmitted on a different frequency (output or direct).

2) A network device that repeats signals from one cable onto one or more other cables, while restoring signal timing and waveforms. Repeaters are the most common way to connect local networks together, and can provide either Thinwire or Thickwire connections. They are commonly used to create larger local networks up to a certain limit based on the number of repeaters and the length of the cables.

3) A device inserted at intervals along a circuit to boost, and amplify an analog signal being transmitted. A repeater is sometimes needed because the quality and strength of a signal decays over distance. Repeaters are also used to regenerate a digital signal - "squaring it" and "cleaning it up" - but not changing it. You can regenerate digital signals because technology exists that can separate the actual signal from the noise, regenerating only the signal. No technology exists that can do this with analog signals. The simplest type of LAN interconnection device is a repeater. A repeater moves all received packets or frames between LAN segments. The primary function of a repeater is to extend the length of the network media, i.e. the cable.

4) someone who is repeatedly arrested for criminal behavior

5) a firearm that can fire several rounds without reloading
The Fairfax County Public Schools use digital trunked repeaters that operate in the 800 MHz range for thier school buses.

The criminal (in your case) used a repeater to kill the police officer.

singles awareness day

Feb. 13th, the day before Valentine's Day. Because so many people don't have relationships (or do, and they hate Valentine's Day anyway), Feb 13th is the day where single people do nothing, there are no cards, no flowers or anything like that.

NTIA

National something i can't remember.

anyway, they "regulate" the world of government and military radio users in the United States of America.

they also have a MAJOR problem with accepting any radio other then a motorola.

Stupid fascists!
CAP guy 1: Fuck the NTIA!!!!
CAP guy 2: Damn right!

testosterone

The male sex hormone, (C19H28O2), screted by the testes, that stimulates the devolpment of the male sex organs as well as the male sex drive.
I'm a 16-year old male, and the testosterone is pretty much flooding my brain.
