A Soundesign pocket transistor radio from the 1960s. SDI Technologies was founded as Realtone Electronics in 1956 by Saul Ashkenazi and Ely Ashkenazi. [3] In that year, the company introduced a pocket cigarette lighter and a transistor radio, but neither one of the first. [4] [5] Realtone went public in 1961. [2]
Stations without the ability to acquire a time signal accurate to at least one second should request a time check at the start of every shift, or once a day minimum. Stations may ask the NCS for a time check by waiting for an appropriate pause, keying up and stating your call sign, and then using the prowords "REQUEST TIME CHECK, OVER" when the ...
A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
After a reset, battery change or power failure, these clocks without a backup battery or capacitor either start counting from 12:00, or stay at 12:00, often with blinking digits indicating that the time needs to be set. Some newer clocks will reset themselves based on radio or Internet time servers that are tuned to national atomic clocks ...

New England Clock Company; New Haven, Connecticut (1959–2000) New Haven Clock Company; New Haven, Connecticut (1853–1959) Parker & Whipple; Meriden, Connecticut (1795–1868)
Basic digital alarm clock without a radio. The mark in the top-left of the display indicates that the time is 4:00pm (16:00), not 4:00am. A 1969 radio alarm clock (Sony Digimatic 8FC-59W) with an early mechanical-digital display. A digital clock displays the time digitally (i.e. in numerals or other symbols), as opposed to an analogue clock.
Sample broadcast clock. A broadcast clock or format clock is a template that displays a radio or television's hourly format in a graphical representation of a clock.Broadcast programming, especially radio, often follows an hourly pattern where certain segments such as news and commercials are repeated every hour at specific times.
[2] Lifting a clock via false handles or non-sturdy components may cause these parts to snap off of the clock, potentially leading to the clock falling and smashing on a surface. b. Over-winding or improper hand setting Improper clock winding and hand setting procedures can cause serious damage to clockwork components.
