EDITORIAL
The announcement that the Government intends to restrict the use of Frequency Modulation to the national broadcasting service is a sad blow to the radio industry. Frequency modulation offers great possibilities for expansion and development, if only we were blessed with authorities who would allow the ether to be as free as the air we breathe or even as open as the roads we travel. The use of F.M. could be a boon to civilisation. Imagine the radio development which would follow if the present broadcasting system was retained intact, but 25 extra F.M. stations licensed in every major town. You could have a station for the local newspaper in Bathurst, for example, as well as one operated by each local church, another by the Masonic lodge, another by the local town Council, one by the local departmental store. And then at Orange, a few miles away, you could have another twenty-five stations, operating on similar wavelengths, yet not interfering with the Bathurst stations. Each transmitter could be a simple affair with a power rating of a hundred watts or less and costing about £100. With such a set-up it would be only a matter of months before every home would have an F.M. receiver a long side the present receiver. What objection can be raised to such a scheme is beyond me. Possibly the present owners of commercial licences would be afraid lest so many additional licences would affect the goodwill of their present licences. As it is, I will be amazed if there is a rush of buyers for F.M. sets on which to receive a relay of the national programme. — A. G. HULL.
