This is a digital re-creation of part of a typical ITA Mendlesham Trade Test transmission in the 1960s using Testcard D and also the start of programmes transmission of the ITA picaso tuning signal start-up sequence. This transmission would have been radiated from the ITA - Anglia Television's Mendlesham, Suffolk, East of England, VHF 405 line transmitter, which had a peak white power of 200 KiloWatts ERP, and was horizontally polarised on Channel B 11. This transmitter also had two high powered relays at Sandy Heath, in Bedfordshire at 30 Kilowatts ERP, Channel B 6 and Belmont, in South Lincolnshire at 30 KiloWatts ERP, Channel B 7.
