    The beep signal is occasionally interrupted by voice messages in Russian. The Pip has been active since 1986, when its distinctive beeping sound was first recorded by listeners, and is a sister station to UVB-76. The station is commonly referred to as "The Pip" among English-speaking radio listeners.

    Therefore, those transmissions would consist of a "beep" (PTT press) followed by Houston talking, then another "beep" (PTT release) and finally the voice of the astronauts. Another misconception about Quindar tones is that they were designed to signal the end of a transmission, similar to a courtesy tone used on many half-duplex radio repeaters .

    Thus the Morse code "dots" and "dashes" are audible as beeping sounds. This technique is still used in radio telegraphy, the local oscillator now being called the beat frequency oscillator or BFO. Fessenden coined the word heterodyne from the Greek roots hetero-"different", and dyn-"power" (cf. δύναμις or dunamis). [11]

    The audible alarm on the Minitor lasts only for the duration of the second activation tone. If there is bad reception, the pager may only sound a quick beep, and the user may not be alerted properly. This can be changed by editing the codeplug's "Alert Duration" from STD to Fixed, the user can then set the alert duration longer than the second ...

  9. Beat frequency oscillator - Wikipedia

    en.wikipedia.org/wiki/Beat_frequency_oscillator

    In the detector the two frequencies add and subtract, and a beat frequency in the audio range results at the difference between them: f audio = |f IF - f BFO | which sounds like a tone in the receiver's speaker. During the pulses of carrier, the beat frequency is generated, while between the pulses there is no carrier so no tone is produced.
