The ZC1 Club was
established by a group of radio enthusiasts based in Wellington NZ to record
the origins of this unique HF radio set developed during the early and
middle years of the Second World War.
The ZC1 Radio was the outcome
of a competition amongst leading New Zealand design teams to design a radio
that could be manufactured in New Zealand under wartime conditions.
The designers had to meet the general specification of the new British No.
19 radio set designed by PYE. The design team from
Collier and Beale, a Wellington based radio manufacturing company, developed
the winning design. Using components largely supplied by the New
Zealand Post Office and with development and construction costs also met by
the Post Office, Collier and Beale were given a contract for the trial
construction of 165 sets.
expectations the ZC1 was put into full production. Production versions
differed slightly in detail from the initial sets the most obvious change
being the use of only one meter. The Mk-2 version produced near the
end of the war introduced further refinements and design change.
