full quieting

A phenomenon on FM transmissions where the incoming signal is sufficient to engage the receiver limiters - thus eliminating the noise due to amplitude fluctuations.

sub rosa

Translated from Latin, this means "under the rose" and is a term frequently used for surveillance but can also mean any type of undercover or discrete investigation. We provide sub rosa/surveillance services both to private parties and to commercial firms.

see pirate radio for where i used this word.

foot warmer

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.

AM

Amplitude Modulation

a way of applying information (voice or music) to a radio signal, beaten by SSB and then FM.

also: the old broadcast band from 530 to 1710 kHz.

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

spread spectrum

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)

Normal scanners cannot get spread spectrum transmissions.
