I tried to find a contact, but can't so figured I'd post this here in case any of the admin type people read it?
England, Scotland, Wales and Northern Ireland - the 'United Kingdom' still have emergency service information in the database for frequencies in the 70MHz spectrum. We did indeed have these frequencies in use, up to just after the year 2000. In 2000 a new company was formed to handle ALL emergency service radio traffic - Airwave was the generic name for the system, although Airwave is actually the company, now owned by Motorola - and is a TETRA network. With the exception of the Ambulance Service in Northern Ireland, all TETRA traffic is encrypted, so public monitoring effectively ceased by the end of 2001 once the system was functional. Northern Ireland have now added encryption to the ambulance service. The analogue system was switched off - leaving a few fire service vehicles with FM radios for firefighter communications on UHF. The old county wide VHF schemes, listed in the RadioReference database have all been discontinued for years, and the smaller UHF local systems went at the same time - previously they were in the 451-452MHz band. Links between the radio sites were VHF in the 146-148 and 154-156MHz bands. These are now empty of Government radio traffic. Realistically, as the only frequency entries seem to be for Police and Fire services, they should be removed as they're only of historic interest now - and are extremely out of date.
