Perhaps this is one of the simplest and smallest FM radio receiver that can receive the FM stations available locally. Its simple design makes it ideal for a pocket sized FM receiver. The output of ...

If you’ve never heard of sferics and other natural radio phenomena ... as [DX Explorer]’s receiver demonstrates. His circuit, which is based on a design by [K8TND], is just a single JFET ...

How on earth could a single transistor form the heart of a radio receiver with enough sensitivity and selectivity to be useful, you ask? The answer lies in an extremely clever circuit: the ...

This two transistor AM radio circuit is also called “mini-radio ... HF-amplifier and function as demodulator at the same time. The sensitivity of the receiver is dependent on the amount of feedback ...

The circuit operates as a radio frequency receiver performing signal amplification, filtering and downconversion mixing. All circuit components are integrated into 0.6 mm 2 area and fabricated ...
