We see this radio circuit is very basic, not too many parts, but still it works. This circuit shows how a full MW radio can be made with very few parts. The main part is TA7642 which already has RF amplifier, detector, AGC inside, so we do not need to build all that outside. Main […]

The Perfect FM Radio Circuit using TDA7000 IC
Here we are going to see how we can build a very simple, yet perfect FM radio circuit using one single IC called TDA7000. This IC already has everything inside it, so we do not need to do too much headache wiring around it. First of all, before we build, we must understand what each […]
Crystal Radio Sets with Amplifier Circuit
A crystal radio receiver, often known as a crystal set, is a simplest form of radio receiver that was widely used in the initial periods of radio. A crystal radio set does not require any external power supply to operate. Instead, it simply makes sound using the energy of the radio signals that is received. […]
Tuned Radio Frequency (TRF) Receiver Circuits
A tuned radio frequency receiver (or TRF receiver) is a form of radio receiver which is made using a number of tuned radio frequency (RF) amplifier stages accompanied by a detector (demodulator) circuit to draw out the audio signal, along with an audio frequency amplifier for amplifying the extracted audio into a loudspeaker. This kind […]
Transmitter Receiver Circuit for 80-meter Ham Radio
This tiny and simple transmitter, receiver set will allow you to communicate over 100 of miles across the world, by tuning to 80-meter amateur ham radio stations. What is 80-meter Band The 80-meter uses 3.5 MHz frequency band for radio communications, which gets the permissions under amateur radio use Between 3.5 to 4.0 MHz in […]
2 Meter Ham Radio Transmitter Circuit
In this post I have explained the complete building procedure of a 2-meter amateur ham radio transmitter circuit, using ordinary electronic components and ordinary test equipment. What is 2-Meter VHF Radio The 2-meter amateur radio band is a section of the VHF radio spectrum, which includes frequencies ranging from 144 MHz to 148 MHz in […]
