This little thread got me thinking . I left Racal in 1986 and had spent the previous year doing production drawings for this.
Cutting edge stuff back then.
1985: Britain gave out its first mobile telephone licences to Racal Vodafone and Cellnet, which simultaneously launched services using Tacs (total access control system)
Telephone of the year was the Nokia Mobira Talkman, thought so fast, light and manoeuvrable that it was advertised by Nigel Mansell.
The Talkman weighed 4.8kg. (about 10 1/2lb) and cost £3,000. Battery life was less than a day between charges. It gave one hour of call time.
