Were you a sparker BigBod _._What a load of tosh! Every ship in the fleet was in touch with the UK 24/7 and vice versa. Back in them days we had teleprinters in the communications office. This was linked to a crypto machine. Signals are received by Radio Automatic Teletype (RATT) Through HF receivers. We could also transmit signals in the same way using murry code tikka tape. To know if the receiving station had received your signal 100% clear and readable (ZBZ5) they would respond to you in morse code. Each signal was given a priority code to determine the time it should take for the recipient to receive the signal. The fastest was a Flash signal denoted by a 'Z' and it would be expected for that signal to reach it's recipient in 10 mins or less anywhere in the world 24/7. There were a lot of Flash signals in 82. Flash signals are rarely used in peacetime.
