Regenerative Receivers techlib
Regenerative Receivers. Regenerative receivers provide a surprising level of performance with only a handful of components. They excel at receiving amplitude modulated signals from below the AM broadcast band up to the higher short wave bands above which the superregenerative detector becomes the better choice.UK Vintage Radio Repair and Restoration RF Signal Generator
This signal generator is intended for realignment of radio receivers. The unit is cheap and fairly basic, but perfectly adequate for its intended purpose.(PDF) EC I Lab Manual | gps damta Academia.edu

Homebrew RF Circuit Design Ideas "There is no such thing as a new idea. It is impossible. We simply take a lot of old ideas and put them into a sort of mental kaleidoscope.1 200 Transistor Circuits
INTRODUCTION This e book contains 100 transistor circuits. The second part of this e book will contain a further 100 circuits. Most of them can be made with components from your "junk box" and hopefully you can put them together in less than an hour.Circuit Zone Electronic Projects, Electronic ...
In the mid 1970s large numbers of small FM transmitters, operating in the FM radio broadcast band (88 108 MHz) appeared on the market. It started with a self build kit from the Danish manufacturer Jostykit that allowed everyone to build a small FM transmitter for a few Euros.Einfacher Mittelwellen Modulator Das Elektronik Labor

Spy Bug FM Transmitter . La dimensione del circuito montato è di 10x17mm e da come si vede in foto i componenti più grossi (fuori circuito) sono appunto il microfono e la batteria, è comunque possibile montare un microfono con ridotte dimensioni, lo si può prelevare dai cellulari di qualche anno fa, sono di piccole dimensioni ed ottima sensibilità..
