Reception Set UHF Special MKII (UK)
Reception Set UHF Special is an early VHF/UHF receiver
covering 27 - 130 MHz in 5 ranges, which was used by the British Army as a
ground or vehicle based interception receiver from about 1941 to about 1944.
The receiver is a conventional single conversion superhet with an IF of 5
MHz, and uses 95x series acorn valves in the RF section and standard octal
based valves in the IF, AF and PSU sections. The construction is of
two separate chassis (one for the RF and one for the IF/AF/PSU), which are
bolted into a heavy steel frame cabinet with top and bottom lids.
The equipment is finished in green wrinkle paint to the cabinet and gloss
green to the front panel (estimated as Brooklands Green).
The equipment was designed and produced by Radio Acoustical Products Ltd,
who also designed the DST1000 receiver. This has a similar construction.
It appears to have been replaced by the R308 later in the war.
|This equipment carries serial
number 78, and is complete but is un-tested. At
some stage in the past it appears to have been serviced with
components dated 1948 and 1950. The condition is good,
with no significant damage and no modifications. Several
wires and solder joints require attention.
The equipment uses close fitting (conformal) 2-piece valve screens which
are pressed to the shape of the octal valves used.
