Last Analogue Transmissions
In accordance with the national Public Safety TETRA rollout programme, existing Police analogue radio systems that were originally installed and maintained by DTELS are being switched off after users have migrated to the new digital network.

Normally, the switch-off goes unnoticed, but in this case DTELS.Org is indebted to Martin Swift for sending in this short audio recording of the last transmission made on West Midlands Police Channel 2 VHF analogue radio system, Callsign Yankee Mike (YM), on Friday 3rd March 2006.  In addition, there is a recording of Channel 1 switch-off, which includes a short period of pip-tone as a nostalgic reminder to all engineers who used to work on these schemes

Martin has sent in the following text to accompany this audio recording:

“Warren, who’s Callsign is Alpha 34, is a Vivista engineer working in the West Midlands Police area, transmitting from their Integrated Communication Control System (ICCS) at Bournville EQR. I was in my car at Romsley, the last station on the Radio Link Assembly (RLA) Quasi-Synchronous (QS) scheme to be switched off was at Sedgley Beacon, which is the one you hear - Marconi RC7000/RC792.
 
Recorded by Warren's colleague, Steve Powell, in Stourbridge. YM analogue VHF is now gone - but was not just switched off !!

This ends my 30-year association with the West Midlands Police analogue radio systems.”
