The 4 metre band

This bandplan is the simpliefied version, without the footnotes. If you want to have the fully detailed bandplan please refer to the VHF managers Handbook

IARU Spectrum Requirement

The amateur service requires an allocation at or near 70 MHz of at least 500 kHz on a secondary basis.

Considerations

In countries where allocated, this band is used for local amateur communication on 24-hour basis, including radio control of objects. Tropospheric scatter and sky-wave propagation (principally sporadic-E) are used for longer distances, as well as auroral propagation at the higher latitudes. Meteor scatter has been used for Morse code and voice communications primarily during meteor showers. Newer computer-based techniques make meteor scatter possible for distances up to 2 000 km.

A Regional allocation is sought for Region 1, where the following countries are already authorized to use all or part of this band: Belgium, Cyprus, Denmark, Faroe Islands, Gibraltar, Greece, Ireland, Italy, Luxembourg, Monaco, Montenegro, Portugal, Serbia, Slovenia, Somalia, South Africa, Sweden and United Kingdom.
