They received no part of the listeners' licences, but were permitted to fund their operations through advertising. "B-class" stations were not encumbered by the same regulations. The number of "A-class" stations in New South Wales and Victoria was limited to two each, and one to each of the other States. The "A-class" broadcaster was permitted to run advertisements of no longer than 5 minutes duration and no more than 60 minutes in any 12-hour period.Run regular programmes of general interest to the satisfaction of the PMG.Make a deposit of £1000 with the PMG and organise a surety of a further £1000 from an approved stakeholder.

In the early days of the tuned radio-frequency receiver the simplicity of a "sealed set" would have been seen as a great convenience.Īmateur constructors were however able to build tuneable (or "open") receivers and thereby gain a wider range of entertainment without fee. In August 1923 laws were passed after an American model, as recommended by Ernest Fisk, by which " Sealed Set" receivers were built to receive a single frequency, that of the issuing company, whose income depended on sale or rental of these receivers, a situation analogous to Pay-TV services today. Broadcast times may have been for only a few hours a day and a few days a week. Program material was supplied by the amateur, and included talks, recitations, readings from books and newspapers, and live or recorded music (in those days no copyright fees were payable). Much interest revolved around reception of distant signals ("DX" in the amateurs' terminology) and much valuable experience in the vagaries of radio propagation was gained by the listeners, many of whom collected "QSL" cards - acknowledgement of a confirmed reception by the transmitting station. Radio receivers were also the province of enthusiasts, who were required to own a listener's licence. Īnother noted pioneer was Charles "Charlie" Maclurcan, whose station 2CM made many distance records on long and short wave, but apparently never experimented with medium wave, the subject of this article. This would be part of the impetus behind the Queensland Government establishing 4QG, Australia's first Government-owned station. One such amateur was Tom Elliot, who in 1921 established station 4CM for its owner Dr. A licence fee was paid to the Postmaster General's Department, renewable every five years.Īmateurs generally designed and built their own equipment.

In the 1920s transmission on the medium wave band was dominated by amateurs who after qualifying by means of an examination and displaying proficiency in Morse code communication (though the band was restricted to telephony), were issued with a call sign consisting of a number denoting for which State the licence was issued (2=NSW, 3=Vic 4=Qld 5=SA and NT 6=WA 7=Tas) and a two-letter suffix of their own choosing.
