Wireless Set No. 62

The Wireless Set No. 62 was a British Army HF band radio transceiver. Introduced by Pye during the later part of World War II as a light-weight and waterproof replacement for the Wireless Set No. 22. Although intended as an interim design, it remained in production until 1966.^[1]

Technical specifications
