Here the AM Radio receiver circuit diagram based on old single IC MK484. Components part list: R9, R10_ 6R8 R6_ 100R R3_ 1K R1_ 4K7 R7_ 5K6 R4_ 10K R2_ 100K R5_ 150K R8_ 820K Pot_ 10K log pot Coil & ferrite bar set C7_ 470p ceramic C, C4, C5, C6_ 470nF monoblock C2_ 100nF. This circuit is a tuned radio frequency (TRF) receiver of the standard AM
AM Radio Receiver - schematic

(amplitude modulation) radio with broadcast frequencies at 550kHz-600kHz. This is a simple and easy to build AM radio circuit which only using two integrated circuits (IC). This circuit works with 9V voltage supply, you could use 9V standard battery to cupply this. This is an active antenna for FM radio receiver, AM radio receiver and SW (shortwave) radio receiver. On the shortwave band this active antenna is comparable to a 20 to 30 foot wire antenna. This circuit is designed to be used on receivers that use untuned wire antennas, such as inexpensive units and car radios. . This circuit is a wireless car alarm system that is built using two circuit modules, namely modules of transmitter and receiver modules. This circuit works on FM radio waves. Car alarms can be used on vehicles that have a 6-12VDC power supply. You can use the voltage stabilizer if your car power supply is too. This is a very simple FM receiver which build based on one transistor only. No chip or another active component. The output is connected to earphones, you need an amplifier circuit if you want to listen the radio with a loudspeaker.
