The main reason for the change was that I did not have the audio transformers required for the original design on hand. The radio is built entirely out out parts from my junkbox and a ferrite antenna LF , tuning capacitor polyvaricon RV , and oscillator and IF coils LF from Jaycar. This post is aimed at those who want to build the receiver using these easily obtainable parts in Australia. I have drawn up a schematic with the circuit changes required to make the receiver work with these parts. The changes are required because the tuning capacitor gangs share a common ground and because the pinouts of the oscillator and IF coils differ to those specified in the design. The radio works a treat. It pulls all the local stations at good volume and with good quality.

Simple FM Receiver

The kind of book from which you learn your craft, and to which you continuously return to as a work of reference. This one was published at the start of the s when Ladybird books were in their heyday, and has the simple objective of taking the reader through the construction of a simple three transistor radio. Including me as it happens, I received my copy in about , and never looked back. When you open the book, the first thing you see sets the tone, for there is a guide to soldering on the inside of the front cover. This is an optional construction method, but it is presented in a style that does not talk down to the reader.

A radio or FM receiver is an electronic device that receives radio waves and converts the information carried by them to a usable form. An antenna is used to catch the desired frequency waves. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation. Of the radio waves, FM is the most popular one. Frequency modulation is widely used for FM radio broadcasting. It is also used in telemetry, radar, seismic prospecting, and monitoring newborns for seizures via EEG , two-way radio systems, music synthesis, magnetic tape-recording systems and some video-transmission systems. An advantage of frequency modulation is that it has a larger signal-to-noise ratio and therefore rejects radio frequency interference better than an equal power amplitude modulation AM signal.
