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.
On May 14, 1963, at 6:30 am, CHED switched to 630 kHz. Beginning in 1959, CHED aired a Top 40/CHR format. [1] Jerry Forbes ran the first 630 CHED Santas Anonymous in 1955. The charity provided 600 toys to children in its first year and is still run annually as of 2020. In the latest edition, the toy drive provided toys to over 20,000 children. [2]
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.
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.
Crystal oscillators can be manufactured for oscillation over a wide range of frequencies, from a few kilohertz up to several hundred megahertz.Many applications call for a crystal oscillator frequency conveniently related to some other desired frequency, so hundreds of standard crystal frequencies are made in large quantities and stocked by electronics distributors.
Deviation is typically limited to 150 kHz total (±75 kHz) in order to prevent adjacent-channel interference on the band. Stations in the U.S. may go up to 10% over this limit if they use non-stereo subcarriers , increasing total modulation by 0.5% for each 1% used by the subcarriers.
