Can a simple medium-wave radio receive shortwave broadcasts? In 2005, Burkhard Kainka answered that question with a creative two-transistor converter.

AT a meeting of the Students Section of the Institution of Electrical Engineers held on November 16, Mr. C. W. Eggleton read a paper on “The Frequency Stability of Tuned Circuits”. The author dealt ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

VARIABLE condensers are now so commonly employed in radio receivers to tune circuits including a constant inductance that the use, some years ago, of variable inductances or variometers with fixed ...

Any radio amateur will tell you about the spectre of TVI, of their transmissions being inadvertently demodulated by the smallest of non-linearity in the neighbouring antenna systems, and spewing forth ...

Excerpted from Digital Receiver Handbook: Basics of Software RadioSixth Edition, this series of articles from Pentek shows how digital receivers, the fundamental building block for software radio, can ...
