Datong Electronics Limited

Datong was an electronics development and manufacturing company, founded in 1976 in Leeds (UK) by David A. Tong. Initially specialising in amateur radio (HAM) equipment, the company later shifted its focus to professional TSCM equipment (bug finders) and radio direction finders (RDF).

In February 2013, following a rocky time on the stock market, Datong put itself up for sale. In June 2013 it was announced that the company had been taken over for US$11.4 million by Seven Technologies Holdings, an engineering business under the umbrella of Seven Technologies Ltd., established in 2005 in Northern-Ireland [1][2].
