Wireless Set No. 38 Mk. 3

Wireless Set No. 38 Mk.3 was based on the No. 38 Mk. II* model but with a much improved netting and tuning facility. In addition, it was tropicalised (hermetically sealed in a die-cast aluminium case) and carried on the operator's back, the control being a mechanically operated remote control. The basic circuit compared to the Mk.II* is not changed very much.

• Crystal calibrator No. 9 fitted to the case for calibrating and netting.
• Case hermetically sealed and tropicalised.
• Standard 150V/3V No. 38 Set battery.
• Issued in 1945.
• Manufactured at Murphy Radio Ltd.
