    The repeating clock was invented by the English cleric and inventor, the Reverend Edward Barlow in 1676. [2]: 206 His innovation was the rack and snail striking mechanism, which could be made to repeat easily and became the standard mechanism used in both clock and watch repeaters ever since. The best kind of repeating clocks were expensive to ...

    Lorimer Burst – Observation of the first detected fast radio burst as described by Lorimer in 2006. [1] [failed verification]In radio astronomy, a fast radio burst (FRB) is a transient radio pulse of length ranging from a fraction of a millisecond, for an ultra-fast radio burst, [2] [3] to 3 seconds, [4] caused by some high-energy astrophysical process not yet understood.

    The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is an interferometric radio telescope at the Dominion Radio Astrophysical Observatory in British Columbia, Canada which consists of four antennas consisting of 100 x 20 metre cylindrical parabolic reflectors (roughly the size and shape of snowboarding half-pipes) with 1024 dual-polarization radio receivers suspended on a support above ...

  5. Amateur radio repeater - Wikipedia

    en.wikipedia.org/wiki/Amateur_radio_repeater

    Repeaters operated by groups with an emphasis on emergency communications often limit each transmission to 30 seconds, while others may allow three minutes or even longer. The timer restarts after a short pause following each transmission, and many systems feature a beep or chirp tone to signal that the timeout timer has reset.

  6. Time signal - Wikipedia

    Time signals on CBC broadcasts may be delayed up to 3 seconds due to network processing delays between the local radio transmitter and the time signal origin in Ottawa. The CBC's predecessor, the Canadian National Railways Radio network , broadcast the time signal over its Ottawa station , CNRO (originally CKCH), at 9 pm daily and also on its ...

  8. Broadcast delay - Wikipedia

    en.wikipedia.org/wiki/Broadcast_delay

    In modern systems, a profanity delay can be a software module manually operated by a broadcast technician that puts a short delay (usually, 30 seconds) into the broadcast of live content. This gives the broadcaster time to censor the audio (and video) feed. This can be accomplished by cutting directly to a non-delayed feed, essentially jumping ...

  9. Radio repeater - Wikipedia

    en.wikipedia.org/wiki/Radio_repeater

    For example, in US two-way radio, 30–50 MHz is one band and 150–174 MHz is another. A repeater with an input of 33.980 MHz and an output of 46.140 MHz is a same band repeater. In same band repeaters, a central design problem is keeping the repeater's own transmitter from interfering with the receiver.
