How to make FM radio easy at home

Components:

  • TA2003P IC
  • 16 Pin IC Base
  • 15pf Capacitor
  • 471pf Capacitor
  • 4.7uf, 25v Capacitor
  • 220uf 25v Capacitor
  • 2pin 10.7MHz Ceramic Filter
  • 3pin 10.7MHz Ceramic Filter
  • Variable Capacitor or Tuner
  • 26Gauge 4 turn and 5 turn coil
  • PCB Board
  • 2n2222a NPN Transistor
  • 1K Variable resistor
  • ON/OFF Switch
  • Speaker
  • Soldering wire
  • Soldering iron
in this project we use ta2003p ic its specially design for radio frequency. 

Circuit Diagram:

  • Ta2003p IC has 16 pin
  • Connect 1st pin with antenna. (you can use any copper wire as a antenna)
  • 2 number pin use for 3v - Negative power supply.
  • 6 number pin use for 3v + Positive power supply.
  • Connect 3pin 10.7MHz Ceramic Filter with 3,6 and 8 number pin.
  • Connect 2pin 10.7MHz Ceramic Filter with 10 number pin and 3v + positive power.
  • Connect 471pf Capacitor with 11 number pin and 3v + positive power.
  • Connect 15pf capacitor with 13 number pin and 2nd side connect with 4 turn coil. and 2nd side of coil connect with 3v + positive power.
  • Connect 14 number pin with 3v + power.
  • Connect 5 turn coil with 15 number pin and 3v + positive power.
  • Connect + Positive side of 4.7uf capacitor with 11 number pin

Now make amplifier circuit:

  • 2n2222a transistor has 3 pin. (1st emitter, 2nd base, 3rd collector)
  • connect middle pin of 1k variable with base pin.
  • connect speaker with collector and 3rd pin of variable resistor.
  • Emitter Connect with 9 number pin of ta2003p ic.
  • Positive side of 220uf capacitor connect with Negative side of 4.7uf capacitor
  • Negative side of 220uf capacitor connect with 1st pin of 1k variable resistor.

Now make Tuner circuit:

Variable Capacitor or Tunner has 3 pin
  • 1st pin connect with 15 number pin of ta2003p ic
  • 2nd pin connect with 2 number pin of ta2003p ic
  • 3rd pin connect with 15pf capacitor
we learn it more batter with watching video.
