ATR4 radio
1 Attachment(s)
Here's a chance to own a unique radio set with a lot of history. The set appears to be a chassis only, so isn't complete, but it's a starting point. I've had two of these sets, they require three dry batteries of different voltages, one battery is for negative biasing the valves from memory, a very strange idea.
https://vkclassifieds.net.au/classif...uff-51352.html These little dry battery sets were issued to various 'stay behind parties' up in the Islands , where they proved to be very successful. I've read a few accounts , here is one https://thelastcoastwatcher.wordpres...-tribulations/ The ATR4 sets were built in Melbourne, which was where the Radio. Corps. factory was located , in South Melbourne. One of their brands was Astor , some of us can recall Astor TV sets. The set has a few nomenclature variables, ATR was part of the RAAF system , but the set has also been found with U.S. Signal Corps. tags.

An interesting little set, Mike. Any idea how big the production run was for it?

Hi David,
Apparently the set was originally made for the Forest Commission Victoria, the military version was manufactured in different models, ATR4A, B, and C. Production numbers would be relatively low, l would think less than 1000 total. Radio Corps were busy , they built sets for the army, navy and air force. The military version of the set could have been even smaller and lighter if they had designed it as a Morse set only. The voice AM modulated circuit was unnecessary , for the sets intended role in the jungles was relaying messages in Morse code, using a cypher . Newspaper article. Sun News-Pictorial (Melbourne, Vic. : 1922 - 1954; 1956), Tuesday 27 June 1939, page 28 Radio Corporation’s New Building RADIO CORPORATION PTY.

History
ASTOR RADIO BEGAN BEFORE
BROADCASTING! The Astor assembly line. IN the year 1922, before broadcasting commenced in Aus- tralia, a retail store in Melbourne began business under the name of Louis Coen Wireless. It sold component parts for radio receivers, and anything at all associated with radio. Amalgamated with it was a small wholesale business of the same type. Large numbers of radio engi- neers, and enthusiasts generally, bought their early valves, crystals, and honeycomb coils from the shop of Louis Coen, when they were playing with a science that has now grown to proportions beyond the dreams of many of them. The original two directors of this firm were Messrs. Louis Abrahams and A. G. Warner. To-day, these men are the directors of Radio Corporation Pty., Ltd., one of the largest radio manufacturers in the Commonwealth. From the little shop in Swanston Street they have progressed steadily, until to-day, although they still have an interest in the retail business, the 500 people and more employed by the firm are engaged in manufacturing radio receivers of every type, and in handling associated business. The "Astorā receivers made by Radio Corporation are nationally known, and nationally advertised, and they sell in such numbers as to place Astor among the foremost names in radio to-day. The early activities of Louis Coen Wireless were so suc- cessful that the directors decided to enlarge their activities. They set up a chain of retail stores in Melbourne, and later in Adelaide. This was the phase in radio during which com- ponent parts were sold in huge numbers, and Louis Coen sold more than their share of them. It was, however, the wholesale business that probably showed the best figures at the peiicd, and in 1928 the turn- over was in excess of Ā£250,000 ! In 1930, when the Scullin Government adopted the tariff schedule which prohibited the importation of receivers from overseas, the directors decided to enter the manufacturing- business. They changed the name of the company to Radio Corporation Pty., Ltd., and under this title commenced the business as it is known to-day. Soon the possibilities of making and selling receivers appealed to the company so much that it gradually relin- quished its activities in retail and wholesale selling.' More and more people were buying radio sets, and soon receivers made by Radio Corporation were distributed all over Aus- tralia. The bigger field of the public which regarded a radio set as a musical box bought to provide entertainment as against the section that bought parts to make the set for them- selves, clearly indicated such possibilities that eventually the wholesale and retail handling of parts was abandoned alto- gether, and receiver manufacturing taken over in real earnest. Radio Corporation had big plans. It was in business to make and sell sets in a big way. Soon it became evident that making the sets was one thingāselling and financing the sales was quite another. Therefore in 1931 the directors decided to commence an entirely new company, known as Radio Finance Co., Ltd., the purpose of which was to pro- vide a flexible and controlled method of financing sales of Astor sets. Some of those early sets made a name for themselves of which the company might well be proud. The famous Astor Neutrodyne was. one of the most popularāthe Baby Astor in its carved table cabinet was a worthy companion. Astor design has always been striving to be the first with the latest, and many of the most modern developments in radio have been seen on the Australian market with Astor right at the front. Astor engineers have never been afraid to pioneer any development which they are convinced will even- tually be adopted in the industry, and very rarely have they been mistaken. The Finance company expanded in direct proportion to the success of Astor sales, and in 1931 the directors felt that it could handle more than mere radio lines. They therefore began to expand the extent of its coverage, and to-day, as Universal Guarantee Limited, it employs a capital of over Ā£lOO,OOO as a public company, and handles considerable busi- ness other than radio. Practically all the apparatus used in radio receivers is covered by patents in one form or another. Radio Corpor- ation was quick to see the advantage of covering itself from this angle. In 1928 it acquired an interest in the patents owned by the Hazeltine Corporation of America, and formed an Australian company, known as Neutrodyne, Ltd., to con- trol this side to its activities. For a number of years Neutro- dyne was content to consolidate its position in Australia, and many patents were filed with this end in view. However, in 1933 the action of the Commonwealth Gov- ernment in terminating its arrangement with other patent interests in Australia Led to a reopening of this very vital matter. As a result, Neutrodyne became very active in its own interests, and eventually joined the present patent pool, which controls such matters, in association with Amalgam- ated Wireless, Philips Lamps, and Standard Telephones and Cables. From this resume of the varied interests of Radio Cor- poration and its associated companies, the full strength of the company in Australian radio matters is very evident. Naturally, Astor sets are best known to-day in their home State, Victoria, although their sales and organisation is Commonwealth-wide. A keen follower of the trends, par- ticularly in U.S.A., Astor has adopted and acquired many ideas from its associates in this country, and applied them to Australia, with special stress on the production of medium- priced merchandise. Some of its later activities, which are bywords now in the industry, are the production of the first widely accepted vibrator battery sets, and an enormous output of car radios. These two lines particularly feature as possibly the best known products of the factory, which now employs 500 hands, and employs a capital of more than Ā£250,000. It is a big step from a retail store in 1922 to such a com- pany in 1937. With the energy and initiative of its direc- tors, Radio Corporation is now one of the biggest names in Australian radio.
