Amateur radio frequencies are allocated by the national telecommunication authorities. Each frequency differs in each location in every country depending on its bandlength. Frequencies in each city differ but some frequencies can reach multiple locations if it is strong enough.

However, the International Telecommunication Union is the primary authority that manages the radio spectrum. This includes all radio transmissions including amateur radio frequencies. Certain standards are set to make sure that the different frequencies do not interfere with one another.

The transmission modes used by amateur radios vary. These include radioteletype, data, voice and Morse code. All of these enable amateur radio stations to transmit signals to a location or city. However, the strength and bandlength of each frequency still vary and this affects the distance it can travel.

Kinds of Amateur Radio Frequencies

This is a frequency having at least 300 MHz while a frequency having at least 30 MHz is called a Very High Frequency. This band allows for high-fidelity audio transmissions otherwise known as FM. Very High Frequencies and Ultra High Frequencies have extremely high data transmission capabilities that cannot be interfered with so easily.

Dual band radios allow for communications on the UHF (ultra high frequency) and VHF (very high frequency) bands in the electromagnetic (EM) spectrum.
