Last summer vacation, I had an opportunity to be in dad's hobby workshop and decided to have a look at my pending projects. (I am no longer a science student but now in School of Fashion Technology for my BS Degree) I realized that I had a lot of parts in boxes that I ordered and must be utilized!! I decided to complete this FM Radio project as all that was to be done was to design a board.

FM Radio project detailed here is based on SONY 1619 chip. This is single chip radio means, everything from Antenna to Speaker is done by Sony IC, specially designed for AM/FM Radios.

Although, Sony 1619 has capability of receiving AM signals too, I have disabled that facility and have made this an FM ONLY radio.

Radio is designed as a School Project where everything that is used is on front side of the board.

There are three coils that we need to wind and a small alignment procedure that will help complete this radio with loud and clear FM Radio Signals!!

Radio is designed on a double sided PTH Board and works on USB power. There is an option to add 6V battery (4xAA or AAA) but that is not part of the kit. USB power is selected in a view that most of us have a PC and one USB port is available for this radio.

A second board is provided to accommodate a 3inch speaker and required spacers are supplied with kits

Since Sony 1619 is a very compact chip with very close pins to solder, we will offer an option to get kits with pre-soldered chip if you like that way. (at no extra cost)

FM Radio kits will be available for school teachers free of charge. Please contact me if you like one for your school.

Speaker for FM Radio is mounted on the back side on a specially designed PC board.
