My name is Alan Copperwaite and I was based in CCE Harrow between 1969 and 1973 in the VHF/UHF labs, Speed cameras and the late lamented Swansea DSBDC experiment before moving on to the Police National Computer Unit. I wonder if any old colleagues visit this site. I only came about it by accident through an amateur radio forum.
Cheers and Merry Christmas
Alan
