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.

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.

emergency

1) A medical or behavioral condition of which the onset is sudden. It manifests itself by symptoms of such severity that a prudent lay person with an average knowledge of medicine and health could reasonably expect that the absence of immediate medical attention would result in: placing the health of the afflicted person in serious jeopardy; placing the health of an individual with a behavioral health condition or others in serious jeopardy; causing serious impairment of the individual's bodily functions; causing serious dysfunction of any bodily organ or part; causing serious disfigurement of the afflicted individual.

2) Any instance for which, in the determination of the President, federal assistance is needed to supplement state and local efforts and capabilities to save lives and protect property and public health and safety or to lessen or avert the threat of a disaster in any part of the United States. Emergency Program: The interim program of the National Flood Insurance Program as implemented on an emergency basis to provide a first layer of subsidized insurance before the detailed risk studies from which actuarial rates are computed have been completed.

3) A. Any occasion or instance--such as a hurricane, tornado, storm, flood, tidal wave, tsunami, earthquake, volcanic eruption, landslide, mudslide, snowstorm, fire, explosion, nuclear accident, or any other natural or man-made catastrophe--that warrants action to save lives and to protect property, public health, and safety (FEMA definition). B. A sudden occurrence demanding immediate action that may be due to epidemics, technological catastrophes, strife or to natural or man-made causes (World Health Organization definition).

4) any sudden unforeseen crisis (usually involving danger) that requires immediate action

radar mile

The time required for a radar pulse to travel 1 mile (~1.6 km) to an object, i.e., to a target; reflect; and return to the receiver. Note: A radar statute mile is approximately 10.8 ms (microseconds); a radar nautical mile is approximately 12.4 s. The time for any other radar unit distance is readily determined, such as the radar meter or the radar kilometer. NTIA
I listen to propagation mapping radar on the 27 MHz freeband.

CDMA

Code Division Multiple Access

A spread spectrum approach for the digital transmission of data/voice over radio frequencies. Sound bits are digitized and the data is split into data packets that are encoded with unique identification tags. All of the data/voice is sent over a spread range of radio frequencies. The cell phone or data device receives all of the data packets but only re-assembles those packets with the correct code and transforms the broken-up bits of data into useful sound and data. This allows more traffic for a finite number of available frequencies than analog or the other digital standards.
My LG phone does CDMA, TDMA, and GSM, as well as analog modes.
