Wireless Set No 10 - Beam Radio

The Wireless Station No 10 was the technological wonder of its time. It used techniques that had not been used before in telecommunications equipment, and it is the forerunner of the modern day radio relay equipment and the radio telephone.

This station provided 8 telephone circuits over a duplex radio path. Each station had to have a clear 'line of sight' path to each other. If the route could not be covered by a single link, up to 7 relay stations could be inserted in the chain.

The station was contained in a 4 wheel 2 ton trailer.

It was first used operationally shortly after D-Day in July 1944 to support the advance of 21 Army Group in the advance across Europe.  'Monty' called it his 'Number 10 Thing'.
