Airways communications was developing in the early thirties and required both medium wave for navigation and high frequency for communications.The commercial market included shortwave relay stations that transmitted programs for rebroadcast at lower frequencies (AM BC Band) in distant areas of the country.No discount dealers, like Leeds, ever offered the AR-60.Apparently, if a wealthy ham wanted the AR-60 he had to order it through an RCA dealer and the receiver would have been found listed in RCA's Broadcast Equipment catalog.The second largest quantity probably went to various commercial users, including RCA installations, with this accounting for probably another 50 receivers. This totals between 280 up to 350 receivers built between 19 with the greatest number going to the military users.The July 2, 1937 disappearance of Amelia Earhart and her navigator, Frank Noonan, near Howland Island while Earhart was attempting a "around the world" flight is well known.
All of the proportions are soooo wrong, there isnt one redeaming feature. Bentley must be holding their sides whilst laughing. This looks a lot better in that regard, though they should have toned down the grill somewhat. The introduction of the Cullinan, clearly demonstrates and confirms, the intention and commitment of Rolls Royce Cars to delight those of their customers who wish to participate in this burgeoning market segment.All production and test for the AR-60 receivers was under Engineer H. The fact that some wealthy amateurs might be interested in a commercial high frequency receiver was explored by placing an ad in QST.RCA did advertise the AR-60 in a few ham radio magazines, with ads like the one from the back cover of the November 1935 issue of QST shown above, but that was the only time in the five years that the AR-60 was available that it was advertised in the ham magazines.The need for a robustly built, commercial level of performance, high frequency receiver was becoming obvious and by 1934, RCA was in the design stages for a modern commercial receiver designated AR-60.Cost wouldn't be a factor and performance was going to be at the limits of engineering design for the technology of the time. It's thought that Leland Thompson was in charge of the electrical design and John Terrell was in charge of the mechanical design. The building of the AR-60 receivers was under RCA Manufacturing Company, Inc., a subsidiary of RCA that handled commercial equipment manufacturing.
