A Bluebell Hill Radio Society project, and construction competition.

This article describes the construction of a medium wave amplitude modulation 7 transistor receiver. It is built from a kit of parts, sourced from ebay, where delivery from WITHIN the UK should be less than £10. The kit itself is of Chinese origin, and with a Chinese set of instructions, much frustration will be had,

What are they, and what are they for? A dummy load takes the place of an antenna. It takes the transmitter power, and converts it to heat. Transmitters that are unable to output the power they have generated tend to suffer damage. When transmitter output stages used valves, they would withstand a “bad load” situation
