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there was a warehouse stacked to the rafters with unused replacement sets, which explained why they had not been superseded by radios of greater power which would have been a boon to us ops on long range Transport Command.
