WIRELESS TRANSMITTER NO 76.
The Wireless Transmitter no 76 was used also in the Battle of Arnhem at the Rear Link contacts to London. See discriptions in the posts Wireless set no 22 and receiver R109.
This transmitter can be only used on CW, telegrafie. It is crystal controlled and has 6 channels. It delivers about 10 watts carrier output. There are only 2 equal valves in use, the ATS 25. Also 2 spares are inserted inside.
Inside is, as a power supply, a rotary transformer power supply for 500 volts. Input voltage is 12 volt DC.
My transmitter is in good, original and working condition. Inside and outside. There are 3 crystals inside in use for me, as a licensed radio amateur, in the 80 meter amateur band. Lately also one for the new 60 meter amateur band.
The CW key is a no 9-a type, which is also there.

Another look at the transmitter with the cables and the 100 ft wire antenna.
The Wireless transmitter no 76 with the receiver R 109 a (T). The R109a was used with the Wireless transmitter no 76.
My whole “Arnhem collection”. The WS no 38 mk2 and mk2*, The WS no 19 HP, The WS no 22, Wireless transmitter no 76, R109 AT and the American portable set, BC 611.
At the left the Wireless set no 19 mk 3 Canadian, the Wireless set 101 Australian, the Wireless set no 11 Australian , the Wireless set no 62 mk2, they were not in use at Arnhem.
It seemed, that the Wireless set no 62, manufactured in the late 1945, was used later in the war, at the Rhine crossings?
The very often published picture of the Wireless transmitter 76/receiver R109 combination in use with the Airbornes at Arnhem. Probably the phantom group for reporting to the press of the BBC in London?
Another picture from the Wireless transmitter no 76 and receiver R109 published in the book of the author Lewis Golden.
Below some pictures of experiments with the Wireless transmitter no 76 and receiver R109-a in the back of my garden. The weather was beautiful, so it was a pleasure to listen to the several amateur stations, at day time on 40 meters and at evening time on 80 meters. The antenna was a dipole antenna, stations were heard in mode single side band and CW. Some contacts with stations were made on 80 meters in mode CW. None on 40 meters, by lack of crystals for that frequency. But the set is suitable for that frequency. Signal reports on 80 meter were very well.
Lately I made some new contacts in the new 60 meter amateur band, with only 5 watts output, but using a dipole as antenna. Amazing!

Left the R109-a receiver. Also to be seen on top of the R109, the WS no 38 mk2.
