The T1154 Transmitter is particularly appealing to collectors of WW II equipment.It’s distinctive,colouration and association with the Lancaster Bomber, may well be significant factors in this appeal.Although its principal role was use as an airborne transmitter,two variants were produced for ground station use ie.,T1154 D & E.Frequency coverage of the airborne units is as follows: T1154,A,B,J &N 10Mc’s to 3 Mc’s and 500 – 200 kc’s,in 3 ranges;T1154C,F,H,K, & M 16.7 to 2.35 Mc’s and 500-200 kc’s,in 4 ranges;T1154L 5.5 to 1.5Mc’s and 500-200kc’s in 3 ranges.The transmitter is provided with a VFO and the frequencies intended for use can be preset,using a click-stop system.Suppressor grid modulation ,by carbon microphone produces useable modulation at a level of around 70%.The P.A. uses 2 directly heated pentodes,type VT104 for an output of 50-80 watts,reduced to quarter power on R/T and M.C.W.Power requirements are 1200 volts,200mA HT (B+);6 volts 4 A L.T.and 6volts 2.5A keying relay.This was originally supplied by rotary converters working from the aircraft electrical system ,or from a.c. mains via transformer/rectifiers,on the ground.Weight of the transmitter is around 47lbs.The transmitter was designed for use with the associated R1155 receiver.At Radio Exports.com, we usually have several T1154 transmitters in stock and a selection of R1155 receivers.From time to time,we also have power supplies;however,these are horrendously heavy and in consequence are expensive to ship.However,if you really want one,just ask for a quotation,but do sit down with a stiff drink,when you receive it!

The T1154 Transmitters which we supply are complete, but untested.If you intend to use these transmitters,it is absolutely essential that you have them examined by a qualified electrical engineer and only use them if he certifies that it safe to do so.Just remember, the wiring is now over half a century old and may well not be capable of handling 1200 volts!
