Emergency communication frequencies

All frequencies listed below are listed in the 2004 UK bandplan as being used by emergency communications groups.

Groups should remember that the UK band plan is advisory and RAYNET groups do not have a "right" to use any frequency. Having said that, most other amateurs will, when asked in a polite manner, move frequency.

The full UK bandplan is available on the RSGB website.
