They are not 'absolute' frequencies but instead are 'centres of activity' and emergency communications may be found ±20kHz from these centres. Some countries may maintain other emergency frequencies in their own bandplans due to local requirements, QRM etc.
REGION 1 HF FREQUENCIESThe countries below have allowed information on their HF frequency usage to be published.
REGION 1 VHF/UHF FREQUENCIES There are no common frequencies for emergency communications in the VHF/UHF spectrum however the bands are heavily used for local communications by national emergency groups. The countries below have allowed information on their VHF/UHF frequency usage to be published and this information was also requested by the C5 committee at the IARU Region 1 conference in Sun City 2011 so that it may be taken into account during bandplanning discussions.
