In response I have had a number of letters from amateur experimenters who want to know why the "hams" cannot be brought to the rescue. Before broadcasting was either national or commercial it was the amateurs who first started sending out music. Right up until just before the last war there were a number of amateur stations allowed to broadcast music and programmes after the ordinary stations closed down, and on Sunday mornings before they opened. Why cannot amateurs be licensed to broadcast with F.M. as freely as possible? They would soon create their own audience and open up a big field for experimenting. F.M. receivers and adaptors are not difficult to build or get going once you appreciate the special technique necessary. At first they seem a little critical but you soon get used to them. Several firms have F.M. adaptors and kits of parts ready for release, but who would want to be forced to listen to nothing but National programmes which are already being broadcast in the ordinary way? Let the amateurs have a go at F.M. and I'll bet that within a few years there will be thousands upon thousands of F.M. sets in use, with quite a revival in the radio industry. Such a plan will not cost the taxpayers a penny, either. — A. G. HULL.
