The UV-5R is designed to transmit on the 2 meter band between 136 and 174 MHz and on the 70 cm band between 400 and 520 MHz. (480 MHz to 520 MHz is not available in the UK to comply with Ofcom regulations and are blocked by the manufacturer).

Frequencies above 30 MHz are referred to as Very High Frequency (VHF) region and those above 300 MHz are called Ultra High Frequency (UHF). The allocated bands for amateurs are many megahertz wide, allowing for high-fidelity audio transmission modes ( FM ) and very fast data transmission modes that are unfeasible for the kilohertz -wide ...
US frequency allocations chart, 2016. Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1]
Many amateurs attribute this to the abundance of commercial radio equipment designed for 136–174 MHz and 450–512 MHz that amateurs could easily modify for use on the 2-meter and 70-centimeter bands. There were no commercial frequency allocations near the 1.25-meter band, and little commercial radio equipment was available.
Band III is the name of the range of radio frequencies within the very high frequency (VHF) part of the electromagnetic spectrum from 174 to 240 megahertz (MHz). It is primarily used for radio and television broadcasting.
151.4825 MHz - 151.9925 MHz 7.5kHz apacing except for the MURS channels and frequencies adjacent to the MURS channels; 152.2625 MHz - 152.480 MHz 7.5kHz spacing may be paired with 157.5225 MHz - 157.740 MHz (5.26 MHz offset, repeater output/base transmit on 152 MHz, repeater input/mobile transmit on 157 MHz. Originally taxi cab radio service.
The 2200-meter or 136 kHz band is the lowest frequency band in which amateur radio operators are licensed to transmit. [ 1 ] [ 2 ] It was formally allocated to amateurs at the 2007 World Radiocommunication Conference (WRC-07).
