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
[edit | edit source]- AM, Superheterodyne radio transceiver.
- 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]
- Antenna Systems:
- Mobile station: vertical rod aerials 4 ft, 8 ft or 14 ft high
- Fixed station: vertical ground mounted 32 ft mast
