Citizens Band allocation in most countries, is slightly higher in frequency than the â¦ Services and â¦ Identify rules and operating devices at the 49.82 MHz to 49.9 MHz frequency bandwidth. Some frequencies may be shared by several Services. 49 MHz is a radio carrier frequency used for the operation of toy radio controlled models. There is a plan that GCC Weather Radio will sign on a frequency of 49.875 MHz and stay there. Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. This article is a stub. Though 49 MHz radios are generally installed in surface models, they can be used in toy aircraft as well since the 49 MHz frequency range is considered to be part of the citizen's band, at least in the US. This site contains information about our club, reference and technical material regarding 49MHz â¦ Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 through 216 MHz, and the UHF band, which comprises channels 14 through 51 and occupies frequencies between 470 and 700 MHz. In toy-grade RCs, the frequency is normally a set channel within the 27MHz or 49MHz frequency range. 49 MHz Update : Coming soon, GCC Weather Radio will be temporarly signing on a frequency of 49.405 MHz since we cannot use 49.860 MHz, and we have to do our best to leave 49.860 MHz an open channel for toy walkie talkies. See the "CONSOLIDATED FREQUENCY LIST" in Police Call Plus Volumes 1 and 3 for specific allocations in these areas. 1.800- 2.000 Mhz: Amateur station operating at 1.900-2.000 Mhz must not cause harmful interference to the radio location service and are afforded no protection from radiolocation operations.
