DTMF

Dual Tone Multiple Frequency. Pressing a button on the keypad of a touch-tone phone generates a pair of tones of specified frequency and duration. The network or the equipment at the other end of the connection (such as a remote control for a phone answering machine, or a telephone interconnect system) detects and interprets these tones. In analog networks, audible tones generated by the network provide the call progress indications to the user. Different tones allow the human ear to interpret the progress of the call. On digital networks (such as PBX or ISDN), the network may send indication messages to the phone to indicate the status of the call, and the phone may generate most tones locally, driven by those messages.

squawk

Pilot slang for the transponder code being used to indentify the aircraft on radar. The code is made up of four digits, and all codes are used but 0000, try using that code in a civilian aircraft and watch how fast the air force lights your ass up. For normal flight the code is 1200, Hijack code is 7500, radio being jammed is 7600 and general mayday call is 7700. These are discrete codes from 7600 to 7677 and 7701 to 7785 also, but I cant tell you what they are for...

Jetblue 834 this is Dulles Control, squawk 4932 please and climb to 15000.

linear

(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.

Yeah, I got a new silver eagle freeband linear, and were putting out a california kilowatt now.
