Simple FM receiver 16MHz- 32MHz on 9 v Battery
Budget: ₹600 – ₹1,500 INR
I am looking for a freelancer to design a simple FM receiver that operates within the frequency range of 16MHz-48MHz. A working design of 93.4 MHz Super Regenerative receiver is already provided for reference/starting point .
This circuit;
-Works with common earphones.
-9V battery source.
-Used common transistor like 2N3904/ BC547. Use 2 numbers or less transistors.
-LM386 for audio amp is connected for volume control.
-No ready made IC is used.
You may modify the circuit , or provide a new type of design. (Superhet etc.)
Provide:
-Excel calculations to show the values used in your own circuit . Biasing resistor, Tank LC values, quenching control etc.
-Model the FM receiver in LTSPICE/ Falstad
Optional : A switch to change frequency to 16/32/48 MHz .
-Use the wire for earphone as antenna by using bandpass circuit or similar.
Modify the provided circuit if required.
The circuit shall be made and verified by the client. After that project will be accepted and paid.
