Senior Constable Downie, affectionately referred to as ‘Pop’, revolutionised police communication.
Downie is pictured here with his portable device, in an era where instead of meaning small or hand sized, ‘portable’ simply meant it could transported – even if it doing so required a V12 car!
Pop first tested his idea for the device on a bicycle, pedalling increasing distances to test its range. Later Pop tested the receiver in a motorcar and found that he was able to receive messages from D24 all the way from the Mornington Peninsular. This unprecedented level of connectivity meant that the Wireless Patrol could be sent to jobs in areas that may previously have been unreachable, in record timing.
