Listening to the CB while driving (also known as "10-10 in the wind"). 10-70 Report a fire 10-100 Restroom break. 10-200 Police needed at _____. (In the trucking-themed movie Smokey and the Bandit, a character jokingly plays off this usage, saying that 10-100 is better than 10-200, meaning that 10-100 was peeing and 10-200 was doing a #2.) 20
Cobra 50 WX ST Handheld CB Radio. Citizens band radio ( CB radio) is a land mobile radio system, a system allowing short-distance one-to-many bidirectional voice communication among individuals, using two-way radios operating near 27 MHz (or the 11-m wavelength) in the high frequency or shortwave band. Citizens band is distinct from other ...
Common emitter. Figure 1: Basic NPN common-emitter circuit (neglecting biasing details) In electronics, a common-emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies, typically used as a voltage amplifier. It offers high current gain (typically 200), medium input resistance and a high ...
No voice transmissions are permitted. It has six channels in the 27 MHz band. Five are unused 10 kHz CB assignments between channels 3–4, 7–8, 11–12, 15–16 and 19–20, and the sixth is shared with Channel 23. R/C transmitters may use up to 4 watts on the first five channels and 25 watts on the last, 27.255 MHz.
Ten-code. Ten-codes, officially known as ten signals, are brevity codes used to represent common phrases in voice communication, particularly by US public safety officials and in citizens band (CB) radio transmissions. The police version of ten-codes is officially known as the APCO Project 14 Aural Brevity Code. [1]
Common base. In electronics, a common-base (also known as grounded-base) amplifier is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a current buffer or voltage amplifier . In this circuit the emitter terminal of the transistor serves as the input, the collector as the output, and the ...
Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup ). In this example, a signal received by the microphone is amplified and passed out ...
Motorboating (electronics) In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.
