CHED has been operating a news/talk/sports format since 1993. [5] The station's current morning show is hosted by Stacey Brotzel and Daryl McIntyre. [14] Former morning hosts have included Ryan Jespersen, who was fired in September 2020 after comments he made regarding a city councillor's staff, [15] and Shaye Ganam, who began hosting a 9 a.m. show simulcast with Calgary sister station CHQR on ...
The 630-meter (or 600-meter) amateur radio band is a frequency band allocated by the International Telecommunication Union (ITU) to amateur radio operators, and it ranges from 472–479 kHz, or equivalently 625.9–635.1 meters wavelength.
ITU Region 1 corresponds to Europe, Russia, Africa and the Middle East. For ITU region 1, Radio Society of Great Britain's band plan will be more definitive (click on the buttons at the bottom of the page). Low Frequency (LF) (30 to 300 kHz) 2200 metres (135.7 to 137.8 kHz) Medium Frequency (MF) (0.3 to 3 MHz) 630 metres (472 to 479 kHz)
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
The 630 kHz frequency is perhaps best known as the longtime home of KDWB from 1959 until 1986. For almost two decades, KDWB was a heated rival of the original WDGY , located at 1130 kHz. When WDGY dropped its call letters in 1991 to become KFAN, KDWB's owner adopted the abandoned WDGY call sign for 630 kHz, where it remained until 2008.
The range originally adopted in 1945 began with channel 201 (88.1 MHz), or a value high enough to avoid confusion with television channel numbers, [2] which over the years have had values ranging from 1 to 83. Having a gap between the highest TV channel number and the lowest FM channel number allowed for expansion, which occurred in 1978 when ...
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave.In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal.
