However, the Image Dissector camera was found to be lacking in light sensitivity, requiring excessive levels of illumination. The Baird company used the Farnsworth tubes instead to scan cinefilm, in which capacity they proved serviceable though prone to drop-outs and other problems.

According to Malcolm Baird, his son, what is known is that in 1926 Baird filed a patent for a device that formed images from reflected radio waves, a device remarkably similar to radar, and that he was in correspondence with the British government at the time. The radar contribution is in dispute. According to some experts, Baird's "Noctovision" is not radar. Unlike radar (except

Baird built what was to become the world's first working television set using items that included an old hatbox and a pair of scissors, some darning needles, a few bicycle light lenses, a used tea chest, and sealing wax and glue that he purchased. In February 1924, he demonstrated to the

This transmission was Baird's response to a 225-mile, long-distance telecast between stations of AT&T Bell Labs. The Bell stations were in New York and Washington, DC. The earlier telecast took place in April 1927, a month before Baird's demonstration.

The conditions in industrial Glasgow at the time helped form his socialist convictions but also contributed to his ill health.

In 1943, the Hankey

From 1929 to 1935, the BBC transmitters were used to broadcast television programmes using the 30-line Baird system, and from 1932 to 1935 the BBC also produced the programmes in their own studio, first at

The trial was due to last for 6 months but the BBC ceased broadcasts with the Baird system in
