Wireless Set Number 48



After the war the No. 48 set was used in Search and Rescue until about 1954, when it was replaced by the TRP1 radio which was specifically designed for SAR use.

The 48 set was notorious for being unreliable and difficult to keep on the correct frequency

The aerial would normally be either a 12 ft whip or a wire dipole strung up in trees etc.

This military man pack transmitter/receiver was developed in 1942 in the USA as an alternative to British No. 18 Set. It was used during WWII for short range communication in forward areas within infantry battalions and artillery
