ww2 & Cold War Radio Sets
The Wireless Set No. 19 was developed in 1940 by the British War Office's Signals Experimental Establishment and by Pye Radio. The Pye model was replaced with the MK II model in 1941, and the MK III model in 1942. The sets proved valuable for armoured fighting in the Western Desert.
In 1942, the No. 19 Mk II was produced in Canada by Northern Electric Co., Canadian Marconi Co. and RCA Victor. The British design was improved and interchangeability of components such as the valves, was instituted.[6] A majority of Canadian sets used English/Cyrillic front panel lettering, the result of a Lend-Lease contract to the Soviet Red Army.[7]

UWPRC320 IS a lightweight flssb rad~os tation
designed as part of the British army's Clansman
range of radio equipment for combat use
throughout the world It IS particularly u~tablefo r
use by long-range patrols or speclal forces
because of its sky-wave range performance and
hand generator system
The equ~pmentIS all sol~d-statea nd operates
in the 2 to 30MHz band w~th lOOHz channel
spaclng, wh~chg lves a cho~ceo f 280 000 frequencles
Selection IS by decade knobs which
control am~cro-m~niatusreyn thesizer locked to a
temperature compensated'reference oscillator,

An alternat~ve verslon (PRC32011) can be
supplied w~thb oth upper and lower sideband In
the ssb mode, compat~ble am, cw (wide) and
w~th1 kHz channel spacing giving 28 000 channels
A transm~tter output power of 30 watts pep
work~ngin to a 2 4-metre (8-foot) wh~pa ntenna
gives PRC320 a rel~able ground-wave communicatlons
range In excess of 40 km (25 miles)
by day under normal condit~ons
PRC320 IS su~table for use as a ground
stat~on,w ork~ngI nto stat~cg round or sky-wave
antennas which greatly increase the d~stance
range
Working into a dipole or end-fed antenna,
skywave communications at ranges from 50 to
