[1] 630 kHz is a Philippine clear-channel frequency used by NTC. DZMM share Class A status at 630 kHz and being defunctional because of legislative franchise lapsed Because 630 kHz is a multiple of both 9 and 10, the frequency is available for use by broadcast stations in all three ITU regions .
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. [13] Former morning hosts have included Ryan Jespersen, who was fired in September 2020 after comments he made regarding a city councillor's staff, [14] and Shaye Ganam, who began hosting a 9 a.m. show simulcast with Calgary sister station CHQR on ...
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.
In the Americas (defined as International Telecommunication Union (ITU) region 2), the FM broadcast band consists of 101 channels, each 200 kHz wide, in the frequency range from 87.8 to 108.0 MHz, with "center frequencies" running from 87.9 MHz to 107.9 MHz. For most purposes an FM station is associated with its center frequency.
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.
The first fully mechanical digital computer, the Z1, operated at 1 Hz (cycle per second) clock frequency and the first electromechanical general purpose computer, the Z3, operated at a frequency of about 5–10 Hz. The first electronic general purpose computer, the ENIAC, used a 100 kHz clock in its cycling unit. As each instruction took 20 ...
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.
