Transmitter Reciever TR9D

[Observer1940]

The T.1083 transmitter and R.1082 receiver was the General Purpose (G.P.) W/T (Wireless Telegraphy) set-up and like the 1940 Whitley V which also used this G.P. wireless combination, bomber aircraft usually had a T.R.9F with the above (although I understand that there was more than one combination). The aircraft would also use its R.1082 receiver (with a 'sense unit') to get D/F bearings from known wireless stations and beacon locations, for navigation purposes and homing.

The T.R.9F could be used in addition to the G.P. equipment and also linked via an amplifier (A.1134) to the G.P wireless. The T.R.9F was similar in circuit (to the 9D), but the T.R.9F gave the bomber a "special" second channel for communication.

The actual T.R.9D and T.R.9F had a similar circuit layout.

I have the R.1082 (3.75Mb pdf doc) and T.1083 (6Mb pdf doc) as two pre WW 2 Air Ministry A.P. 1186 docs (they can be found online free of charge at
T1083 - BAMA - edebris.com (or Googling this bama.edebris.com/manuals/britmil/t1083 ) click the "T1083.pdf (5 MB)" link only
and
http://www.ww2aircraft.net/forum/com...nual-8701.html (log in and click the pdf conversion)

Both go into a little more detail as to what can and cannot operate, when certain aspects of the wireless are in operation, circuit diagrams, switching arrangements, additional equipment, photographs and A.M. part numbers etc.

I'm going to really read it all up thoroughly too.

Don't forget the 5 pages of Chapter 10 on the "Transmitters-Receivers T.R.9D and T.R.9F" at http://www.tuberadio.com/robinson/Information/TR9D/ (link given in a previous post by MarkRS to 5 page links), which you can click on to enlarge and then print off each page (by adjusting on your pc 'print preview' menu zoom %).
