IMPROVEMENT OF TRANSISTOR CODE PRACTICE DEVICE,
Abstract
The paper suggests some renovation for a transistor radio-signal transmission exercising device proposed in an article appearing in Wu-hsien-tien, pointing out some of the short-comings of that device. The renovation calls for simplifying the circuit of the old device, and reducing the voltage. This makes it possible to place the whole device into a transistor radio case, so that it can be carried by the user. Technical drawings showing the difference of the old and new devices are given.
