JULY 1960

 

 

The July 1960 was an issue dedicated to the technological news: the TRANSISTOR.

As You can see, great emphasis is given to an article devoted to the all transistor super-regen receiver and to the transistor theory. Please, remember that the articles was written in 1960 and the electronic technological development still considered valves (electronic tubes) more suitable for the radio frequency than transistor.

 

In the ’60 years, valves (electronic tubes) was universally used, mainly in the radio-frequency part of a radio rig. The use of all transistor in a radio receiver to be built by home constructors was an absolute challenge! The article demonstrated that this was possible and, for this goal, complete description of assembly was given, joined with electric drawings, drilling jig for chassis and component layout. A "state of the art" for transistor amateur radio project.

 

This was an year of great pride for the Great Britain modelers that competed for the records in the aeromodel field. Charles Dance and Wally Skeels was the couple of Englishmen that obtained the distance record for an R/C model sponsored by the Taplin Engine firm. The article tells the story, from the project of the model, the technical solutions to be able to use the ’60 years radios, up to the race itself . Delicious photos complete the article of the event.

 

Is curious to note that when valve radios and transistor radios cohabited, various voltage was need so various batteries was available for power supply. Also, not being a standard for all, various sockets was present. A pull-out battery equivalent and socket data sheet was offered in the central pages of the issue. See and enjoy our present day standardization!

 

Is far away from our thoughts to consider various commands given pressing a single button, but this was the "single channel" and was not proportional. Ingenuity developed many devices to obtain the desired movement of the desired surface in the model, by a radio with only a channel available. These items was called "actuators", powered not by cells (Ni-Cd or dry cells), as usual in today ours very much sophisticated radios, but by winding rubber bands. The article explain their use and operation so You will know new words as "compound", "quick-blip" and others.

 

 

Here we are in the advanced technology: the TRANSISTOR. The electronic component was considered a mysterious device by a great population of modelers. To throw a light Dave McQuee, the expert of the argument, describes the simplified theory behind the transistor, to give to the average R/C modeler the basis to understand its applications in the R/C field. Up to little years, electronic tubes disappeared from the radio control rigs, as from others instrumentation or home electronic/industrial devices.
