462 MHz and 467 MHz - what Band?
« on: August 22, 2020, 12:27:11 AM »

Anyone know what frequencies 462 MHz and 467 are in what band? Not 10, 11, or 12?

It may be helpful for you to know how to calculate the "band" that hams are always talking about. It is really the wavelength of the frequency (in meters):

           Wavelength = 300/fMHz

So our 29 MHz frequency that we call 10 meters comes from 300/29 which is approximately 10. We tend to round the wavelength  to some convenient number.

For your 462 MHz GMRS example, it becomes a fractional number: 300/462 is approximately 0.65 meters. So we would tend to call this 65 centimeters (65 cm). The closest ham band to this is 70 cm.

Those are for commercial use such as 2 way, paging, Public Safety, GMRS at 462 and 467, as well as unlicensed very low power use such as hand held transceivers. Collectively called UHF low band and Business Band they cover 450-470 MHz with some special permission to 512 MHZ in urban areas
