(radio)
a radio transmitter which is designed or modified to send a signal which deliberately inferes with another radio signal. (see also FRS jammer)
Jammers are most widly used by thegovernment and military in order to make it harder for the enemy to use their radio systems.
Also fun when directed at a rap radio station.

Get the Jammermug. An exclamation, from the 70s show Emergency.
It comes from the fire department dispatch guy that goes "Squad 51!"

Get the Squad 51!mug. the PRC doesn't stand for anything.
the PRC-77 (and the improved PRC-770) are military VHF FM transcievers, that have been used sence 1960, and are slowly being phased out because the US Army likes them.
Frequency Coverage:
30.0000 to 76.0000 MHz
channel spacing:
50 kHz
channels:
920
Power Output:
5 watts
Range:
10 miles on a bad day
5 miles when the VC are shooting at you
30 miles when you get back to base
PRC-77s are used as manpack radios (straped to the back of GIs and used for unit-to-unit communications), if you've ever seen the movie "Platoon", the PRC-77 is the radio that all the Americans are carrying on thier backs.
or they are installed as radios in Humvees and tanks. (i.e. all the antennas on military viecles are connected to PRC-77s.
widly copied by every NATO member, so all the good guys can talk to each other.

Get the PRC-77mug. (Repeater Term) A condition experienced on VHF and above where a signal rapidly fluctuates in amplitude causing a sound akin to rubbing a stick on a picket fence. If a repeater user's signal isn't strong enough to maintain solid access to the machine's input (such as when operating from a vehicle passing beneath underpasses or through hilly terrain), the signal would be hard to copy because of a pronounced, rapid fluttery or choppy characteristic.

Get the picket fencingmug. High Frequency
radio communication services from 1.8 to 29.7 MHz, used for long-range communications, the only band used for worldwide communcations other then mircowave and UHF satellite services

Get the T-3 linemug. (radio slang)
An amplifier used after the transceiver output. So named for its purity of amplification. Linear, in the mathematical sense, means that what comes out is directly proportional to what goes in. As far as linear amps go, if you double the input, the output is doubled and so on. This does not generate any additional frequency byproducts. If the amp is nonlinear, sums, differences and all combinations of those are generated also.
