The experiment was first reported to Directorate staff in Intercom Journal No 1 (Pages 22-23) in January 1972.
Further articles appeared in Intercom Journals during the 1970’s as the experiment progressed, details of which can be found as follows:
Intercom Journal No.2 - Jun 1972 (Pages 41-45)
Intercom Journal No.4 - Nov 1973 (Pages 12-16)
Intercom Journal No.8 - Jun 1976 (Pages 21-22)
The conclusions extracted from Intercom Journal No.4 indicated that the trial run had shown that useful and valid quantative deductions could be made about the queuing situation on a police voice channel without disturbing the channel users; and that the method employed would be sensitive to the introduction of mobile data aids.
The method was incorporated by the study group in a scenario for the MADE experiment, together with other more subjective assessment methods.
By 1976 the project had moved on to Stage II and Intercom Journal No.8 had reported that the Marconi Company at their Chelmsford Research Laboratories were in the process of producing production prototype equipment for trial.
Around the same time, Marconi produced a six page publicity brochure shown in the gallery opposite, which described the experiment, the trial location and gave a brief description of the system constituent items.

The pictures are believed to be copyright of ‘The Marconi Company’ and were amongst papers recovered from the Home Office Directorate of Telecommunications Technical Library in 1994.
