Directorate of Telecommunications
POLICE SERVICE; Thames Valley
This section currently contains four short videos produced by the Thames Valley Police Television Unit in association with the Directorate of Telecommunications in 1987.
The videos were a users guide to the introduction of VHF/UHF mobile equipments entering service with UK Police Forces following frequency changes arising from the 1979 World Administrative Radio Conference (WARC). It is not known for certain whether the videos were ever distributed outside of Thames Valley Police (TVP) to other forces. However, the Directorate is credited with providing a technical advisor, Brian Ellis, during the production of these videos
The four videos in question related to:
- The Standard VHF Radio (Marconi RC690)
- The VHF Relay Radio (Marconi RC690 with UHF facility)
- The Motorcycle Radio (Burndept BE536)
- The VHF/UHF Repeater Radio (Burndept BE540)
Runtime varies between 6-15 minutes duration.
