HOW TO MAKE FM RADIO RECEIVER AT HOME
DESCRIPTION
How to make a radio at home from a DIY electronics kit very small and cheap compact, relatively easy to make
all the problem will be presented in the next steps
The hart of this radio FM receiver kit is the chip HEX 3653 the rest are very easy and common components:
5 switches
3 capacitors +2 electrolytic capacitors
3 resistors
1 inductor
1 quartz and an transistor
This main component is the hardest thing to solder for a beginner for this you should watch the video representation from the end of this tutorial because this is a surface mount chip is more time consuming but nothing impossible if i can make you will not have any problem assemble this diy electronic kit of a radio fm receiver.
In radio communications, a radio receiver (receiver or simply radio) is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information
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.
The information produced by the receiver may be in the form of sound, moving images
A radio receiver may be a separate piece of electronic equipment, or an electronic circuit
within another device. Radio receivers are very widely used in modern technology, as components of communications, broadcasting, remote control, and wireless networking systems. In consumer electronics, the terms radio and radio receiver are often used specifically for receivers designed to reproduce sound transmitted by radio broadcasting stations, historically the first mass-market commercial radio application.
You have the picture above on the last hard component to solder are those 3 capacitors ,because there is no schematic you have to be careful about the small capacitor should be mounted in the right end side and the rest just try it out to see what anthena do you need for the diy electronics radio assembled at home
