Read moreHow does the frequency spectrum work?
How radio frequency works. Radio frequency is measured in units called hertz (Hz), which represent the number of cycles per second when a radio wave is transmitted . One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second.

FCC range for VHF is 145.2-147.39 Mhz. This radio goes from 136-174 Mhz, well outside authorized range . FCC range for UHF is 442-450 Mhz. This radio goes from 400-520 Mhz.
Read moreWhat is FCC frequency?
The FCC regulates radio frequency (RF) devices contained in electronic-electrical products that are capable of emitting radio frequency energy by radiation, conduction, or other means. These products have the potential to cause interference to radio services operating in the radio frequency range of 9 kHz to 3000 GHz .
Read moreWhat is frequency channel spacing?
Channel spacing, also known as bandwidth, is a term used in radio frequency planning. It describes the frequency difference between adjacent allocations in a frequency plan .
Read moreWhat frequencies are used in space?
Radio frequency communications for spacecraft are conducted between 30 MHz and 60 GHz . The lower frequency bands are typically more mature for SmallSat usage, however extensive use of these bands has led to crowding and challenges acquiring licensing.
Read moreWhat is the purpose of frequency allocation?
The International Telecommunication Union defines frequency allocation as being of “a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions “.
