Amateur radio has been a popular hobby since the early 1900s.

A dual band radio is a communications system that is designed to allow operation on two separate frequency bands. This operation can be one of many types of transmission and reception arrangements depending on the capabilities of the individual radio.



Dual band radios allow for communications on the UHF (ultra high frequency) and VHF (very high frequency) bands in the electromagnetic (EM) spectrum. In amateur radio jargon, the VHF band is called the "2 meter band" and ranges from 144 MHz to 148 MHz. The UHF band is called the "70 centimeter band" and ranges from 420 to 450 MHz.
