Avro Lancaster Mk X Bomber Plane
The Avro Lancaster Mk X was the Canadian built version of the British built Avro Lancaster B III, a later variant of the RAF Bomber Command's original Avro Lancaster B1, the main difference between the UK and Canadian aircraft was the use of Canadian and American instrumentation and electrical components. A total of 430 Avro Lancaster Mk X's were built by Victory Aircraft in Malton, Ontario in the last three years of WW2, they were flown to Britain unarmed across the Atlantic where they were armed before becoming operational. It is note that the Royal Canadian Air-Force (RCAF) continued to operate the Avro Lancaster in a variety of roles until mid 1963.
The picture above depicts the Avro Lancaster B X FM213 belonging to the Canadian Warplane Heritage Museum and is dedicated to the memory of Pilot Officer Andrew Charles Mynarski VC, it is one of only two Avro Lancasters maintained in an airworthy condition, the other being the Lancaster B1 of the RAF's Battle of Britain Memorial Flight (BBMF).
It is of note that during WW2 Avro Lancasters dropped 608,612 tons of high explosives and in excess of 51 million incendiary bombs with an average combat life expectancy of approximately 21 sorties per aircraft (about 160 mission flight hours).

T1154 transmitter & R1155 receiver as used on the Avro Lancaster
The R1155 aircraft communications receiver, and it's associated T1154 transmitter, were developed from a Marconi design for RAF use in it's medium and heavy bomber aircraft.
One early problem OF notable with the R1155 super-heterodyne radio communications receiver proved to be the unwanted reception of Radio Athlone, a Republic of Ireland national radio station, this could make the reception of any other signal impossible at some locations over Europe, this was due to the R1155's 560 khz intermediate frequency being the same as the Athlone radio station's transmitting frequency resulting in RF breakthrough in the radio's IF stage.
The problem proved sufficiently serious to require two special "Athlone" filters to be designed, fitting them proved difficult as the radio was very compact in design and there was very little empty space inside the chassis to fit the two filters in.
