| Communications Receiver R1155 R1155B R1155C R1155D
R1155E R1155F R1155L R1155M The 1155 receiver was fitted into the
Lancaster bomber and marine craft such as motor torpedo boats, in
conjunction with the 1154 transmitter there purpose was communications and direction
finding.
There were several versions of them made covering different
frequencies.
Coverage is from 18.5mc/s to 200kc/s with a gap between
600kc/s and 500kc/s.
The set draws 114watts from the power supply,
maximum power output 100 milliwatts 5000 ohms impedance.
The aircraft
version had an aluminium case for obvious reasons where as the marine
version had a steel case.
The weight of these units are 33 lbs
6oz.
The sets photographed on the right are fully operational .

Additional information on the
Wireless Set 1155
Receiver
Kindly
supplied by Bob Fairman.
The Lancaster was not the only
aircraft in which this equipment was installed.
They were used extensively
in aircraft of all types in the RAF during and after WW2.
I used them
during the whole of my time in the RAF from 1949 to 1957 and they
continued in use for some years after that.
During that time rumour had it
that in a storage depot 'somewhere in England' there was a warehouse
stacked to the rafters with unused replacement sets, which explained why
they had not been superseded by radios of greater power which would have
been a boon to us ops on long range Transport Command. |
