Amateur radio frequency allocations



Amateur radio frequency allocation is done by national telecommunications authorities. Globally, the ITU oversees how much radio spectrum is set aside for amateur radio transmissions.

Radio amateurs use a variety of transmission modes, including Morse code, radioteletype, data, and voice. Specific frequency allocations are a matter of record and vary from country to country and between ITU regions.

FCC Part 97.301 (courtesy of ARRL) includes a table comparing frequency allocations for all three regions.

Contents

ITU Region 1

For ITU region 1, Radio Society of Great Britain's band plan will be more definitive.

  • Low Frequency (LF) (30 to 300 kHz)
    • 136 kHz (135.7 kHz to 137.8 kHz)

...

  • Very High Frequency (VHF) (30 to 300 MHz)
    • 4 metres (70 to 70.5 MHz), UK only

However there are also 4m amateur allocations in other ITU Region 1 countries e.g. Ireland 70.125 to 70.450 MHz

Table of Amateur MF and HF Bandplans

The following charts show the voluntary bandplans used by amateurs in Region 1. Unlike the USA slots for the various transmission modes are not set by the amateur's licence but most users do follow these guidelines.
