To heck with HDTV! Terra Media has a great PDF of how to build a Baird Televisor! – “”Many of the earliest television receivers were home made, either from parts bought by hobbyists from electrical suppliers or from kits sold by Baird Television. These articles were published in Television, the ‘official organ of the Television Society’, between March and May 1928. They give full instructions of how to build a Televisor and operate a television link between two rooms.”” Thanks Azog! – Link.
