How to Make an FM Radio Receiver: A blog about how you can turn an old radio into a FM radio receiver.
You must have heard of the FM radio and how it provides good quality sound, better than the AM radio. You may have also seen a number of people using the FM radios. However, did you ever thought about making one yourself? Well all that you need is some information and guidance about how to make an FM radio receiver. If you are interested in making your own FM radio, then this is the place for you.
In this article, we shall guide you on how to make an FM receiver from scratch, with all the necessary things required for it and some detailed instructions as well.
There are basically two types of receivers; namely, the super heterodyne receiver and the direct conversion receiver. We shall guide you how to make an FM receiver based on both these types of receivers in order to help you gain a better understanding about these concepts and also to provide you with a better comparison between them.

So, you’re looking for information about how to make an FM radio receiver. You’re in luck! In today’s post I’ll show you how to do this.
As in the last post, I’ll assume that you have no electronics knowledge and start from the ground up. If you’ve previously built things like amplifiers, then some parts of this may seem trivial to you. But there’s so much here that it’d be hard to really skim over anything without having to go back later on.

Here is a project that will let you turn an ordinary old radio into a really cool FM radio receiver. The finished product will look like a regular radio, but instead of broadcasting AM or shortwave signals, it will be broadcasting an MP3 file from your hard drive.
The hardware for this is pretty simple: just an Arduino, an old radio, and a few pieces of wire. You will also need some software to upload the sketch and convert the audio file to the right format.
The idea here is pretty simple. We will open up the radio and connect the Arduino’s digital pins to the tuning knob on top of the radio. Then we can use the Arduino to tune in to any station in the FM band (in this case between 88 MHz and 108 MHz).
We can then send any audio data we want to that frequency, and our radio will play it!
We have a very old radio that we got from our grandmother, and it still works great. But now that we have a new car with an FM radio, it seems like all the good stations are on FM. And so we wanted to convert this old radio so that it could play those new fangled FM stations.
It turns out there is a simple way to do this, because most radios already have the guts to receive FM signals, they just need some extra parts, like an antenna and a tuning knob. After searching around on some other sites (like this one), we figured out how to do it and made our own little tutorial.
First you will need what I call the “guts” of the radio (the parts inside) which for us was an old AM/FM clock radio. The first thing we did was take these guts out and examine them. You can see a picture of them below:
As you can see from the picture, there are not many parts inside that are needed for our project. We only really need three wires (the two antenna wires and the ground) and two chips (the AM chip which would be removed later) . If you want to go with this same setup, then your best bet is probably to find a
The voltage divider is a simple circuit which taps off a fraction of the input voltage to provide an output voltage which is proportional to the input. The fraction is determined by two resistors, R1 and R2.
The formula for calculating the output voltage is:
Vo = Vin * (R1/(R1+R2))
In this case R1 = 820k and R2 = 1M, so the equation becomes:
Vo = Vin * (820k/(820k+1M))
= 0.4526 * Vin
Electronic music is a form of music that employs electronic musical instruments and electronic music technology in its production, an electronic musician being a musician who composes and/or performs such music. In general a distinction can be made between sound produced using electromechanical means (electroacoustic music), and that produced using electronics only.
Electromechanical instruments include mechanical elements, such as strings, hammers, and so on, and electric elements, such as magnetic pickups, power amplifiers and loudspeakers. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar, which are typically made loud enough for performers and audiences to hear with an instrument amplifier and speaker cabinet. Pure electronic instruments do not have vibrating strings, hammers, or other sound-producing mechanisms. Devices such as the theremin, synthesizer, and computer can produce electronic sounds.
The first electronic devices for performing music were developed at the end of the 19th century, shortly afterward Italian futurists explored sounds that had not been considered musical. During the 1920s and 1930s, electronic instruments were introduced and the first compositions for electronic instruments were made. By the 1940s, magnetic audio tape allowed musicians to tape sounds and then modify them
