Precise timing of events such as transmitter switch-on and closest approach was important to analyses that were being undertaken.
Clocks were used to keep track to the nearest minute then the stopwatch provided the seconds readout. One method was to start a stopwatch on the occurrence of an event such as transmitter command-on and then stop it against the one minute marker in a radio time signal from the MSF or DIZ transmitters. The log entry would read something like "Commanded on xx seconds before xx:xx UTC....".
The modified PYE marine transmitter/receiver that can be found in the Receiver list was dedicated to time signal reception.
