Pye PF1 'Pocketfone' Personal Radio (1960s-1970s)
These were the first type of personal radio issued to the police in south Wales in the mid-1960s, and remained in use until the mid-1970s. They came as either transmitters or receivers. Usually the Sergeant carried the transmitter with which he could send messages to his Constables. They however could only listen and not reply.

In the mid-1980s the Burndep radio which combined both transmitting and receiving functions replaced the PF1.

Motorola HT600 E Personal Radio
In 1988 the Motorola replaced the Burndep. It was carried in a leather pouch and attached to a belt.
