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]

• Frequency coverage: 1.6 to 4.00 MHz and 4.0 to 10.0 MHz in two switched ranges. ^[2]
• Receiver sensitivity (20 dB signal-to-noise ratio when modulated 30% at 400 cycles): 1.6 to 4.00 MHz, better than 3 μV; 4.0 to 10.00 MHz, better than 6 μV. ^[2]
• Intermediate frequency: 460 kHz ^[2]
• Receiver Audio output: 200 MW at 1 kHz ^[2]
• Transmitter RF output: 1 W
• Circuitry: 11 valves ^[2]
• Weight: WS62 transceiver unit (excluding accessories) - 13.7 kg
• Dimensions: 515 x 260 x 324 mm
• Power Supply: 12 V DC at 3.0 to 5.0 Amps from external batteries, powering an internal rotary transformer (motor-generator). Later models used a transistorized inverter power supply. ^[2]
