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.
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 ...
WBMQ (630 kHz) was a commercial AM radio station in Savannah, Georgia. It was owned by Cumulus Media and aired a news/talk format. The studios and offices were on Television Circle in Savannah. [1] The transmitter was off Dulany Avenue near the Savannah River. [2]
630 metres – 472–479 kHz; Just below the commercial AM broadcast band and the maritime radio band. 160 metres – 1 800–2 000 kHz (1.800–2.000 MHz) Just above the commercial AM broadcast band. Allocations in this band vary widely from country to country; it was formerly shared with the largely defunct Loran-A radionavigation system.
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 clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), the first personal computers (PCs) to arrive throughout the 1970s and 1980s had clock rates measured in megahertz (MHz), and in the 21st century the speed of modern CPUs is commonly advertised in gigahertz (GHz).
Consider, for example, a 6-MHz carrier modulated at a 3.5-MHz rate; by Bessel analysis, the first sidebands are on 9.5 and 2.5 MHz and the second sidebands are on 13 MHz and −1 MHz. The result is a reversed-phase sideband on +1 MHz; on demodulation, this results in unwanted output at 6 – 1 = 5 MHz.
