A waterfall plot for FT8 signals (bandwidth 50 Hz) in the 40-meter band and for JT65 on the right (bandwidth 180 Hz) Joe Taylor, K1JT, announced on June 29, 2017, the availability of a new mode in the WSJT-X software, FT8. [11] FT8 stands for "Franke-Taylor design, 8-FSK modulation" and was created by Joe Taylor, K1JT and Steve Franke, K9AN.
WSPR (pronounced "whisper") is an acronym for Weak Signal Propagation Reporter.It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators.

Optical cesium atomic clocks - Oscilloquartz has developed optical cesium atomic clocks that are more stable and accurate than magnetic cesium-based solutions and exceed the current ITU-T G.811.1 enhanced primary reference clock (ePRC) specification. The current highest-end clocks in this range combine with core grandmaster devices to provide ...
Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift , caused by clocks counting time at slightly different rates.
The company gave the project to an 18-year-old engineer, Harry Lampen Edwards, who was seconded to the Observatory. The pips were originally controlled by two mechanical clocks located in the Royal Greenwich Observatory that had electrical contacts attached to their pendula. Two clocks were used in case of a breakdown of one.
Windows Clock (known as Clock & Alarms on Pocket PC 2000, [2] Alarms on Windows 8.1, and, until July 2022, Alarms & Clock on Windows 10) is a time management app for Microsoft Windows, with five key features: alarms, world clocks, timers, a stopwatch, and focus sessions. The features are listed on a sidebar.
All Apple Mac computers store time in their real-time clocks (RTCs) and HFS filesystems as an unsigned 32-bit number of seconds since 00:00:00 on 1 January 1904. After 06:28:15 on 6 February 2040, (i.e. 2 32 − 1 seconds from the epoch), this will wrap around to 1904: [ 5 ] [ 58 ] further to this, HFS+ , formerly the default format for most ...
