Sets No. 62 MKII
Wireless Sets No. 62
was a
low power short range vehicle station HF transmitter & receiver.
It
was intended as a lighter and water proof replacement for Wireless Set

22 MKI, which had been in service since 1942. The frequency range
is
1.6 to 10.0 MHz.
Designed and produced by Pye Ltd in
Cambridge,
WS 62 had a long service life, being first trialled early in 1944, with
production
running from late 1944 to 1966.
The equipment was of
mainly
aluminium construction, was water resistant, semi-tropicalised and will
float.
It weighs approximately 30lbs, and was used as a vehicle mounted
mobile
station, a man-pack set and
as an animal-pack set in both Europe and the Far East.
The
transmitter power output was approximately 1 Watt into a vertical rod
or
long wire antenna. The equipment was powered by a miniature rotary transformer mounted
inside
the case and supplied from external 12 Volt batteries.
A
separate
unit, Crystal Calibrator No. 10, was used as a frequency setting aid.
