|Transmitter / Receiver TR1143|
|This is my little collection of TR1143 parts. The TR1143 was a British transmitter / receiver used for airplanes and ground stations during WW2. The frequency range is 100..124 MHz. Output power of the transmitter is some 10 Watts using 2x TT11 (VT501).|
Transmitter Type 46, Serial 44107|
This transmitter seems to be converter by a radio amateur for use at 2m.
Receiver Type 71, Serial 36435|
This receiver was probably used for spareparts. There is not much left except for some tube bases and mf filters.
Transmitter Type 50, Serial 2068|
This transmitter is still rather complete. It could be restored to operate again.
Receiver Type 71, Serial 37687|
This receiver was converter for FM reception. The last mf filter coil was modified and an extra base for a 6H6 is fitted. The modifications are not very neatly done. I would be surprized if this has ever worked as FM receifer.
Receiver Type 68, Serial 41688|
This receiver misses some components and could be restored to operate. It looks like it was originally equipped with 8 crystals in stead of the usual 4.
