Radio Room EquipmentThe QE2 Story would like to thank Radio Officers, Willum and Roger Latham for providing information and photos for this topic. International Marine Radio Company was responsible for the whole installation on QE2. They engineered and installed the system including the four simultaneous conversation and the two picture circuits
"The quality of the original installation was excellent. The drawings and wiring looms were beautifully done and a number of complex units were made especially for QE2, in particular the control units for the telephone exchange, the duplex units and the rack known as ‘The Coffin’ that contained the speech inversion devices. Speech inversion was known as ‘Condition A’ but all it did was swap from upper to lower sideband so like all the short wave phone calls could still easily be listened in to by short wave listeners. Portishead didn’t have it but Ocean Gate Radio in the USA would occasionally suggest Condition A" Willum
