LM386 Shortwave radio

Lm386 Ruby guitar amplifier circuit

3 Ohm coil used as input

Picking up a Puerto Rican Transmission

THIS IS SO COOL! Yea, The circuit is meant for amplifying signals from a guitar, but the same principles apply with the voltage received on a coil of wire. Vawala, Radio

oh these lm386s, just making a regular old amp but on a breadboard with all the extra un-insullated wires and i was picking up very faintly the local fm station a 97.7fm, nuts

@BlanchProductions yea these things really aren't suited for any application that calls for accuracy or stability

[tiputipu0052]

if i have to make transistor radio...could you just please tell me where i have to put tank coil (emitter, base or collector) and where i have to put feedback coil??? is the areal wire you have shown with 4 turns, the same called feedback coil??? what is the function of feedback coil and where it is plased in transistor please help me...dont discuss amplifier, i want to know about the first circuit,amplification comes next stage...please help.

@tiputipu0052 dude, sorry but the interwebz wuz inventionesd for a pourpoz

Where can the circuit be obtained at? There are lots of them out there, but which one did you use to make this work?

[smartpartzzkidd]

@gccengineering1996 really just any low power op amp will do it, I just used a test circuit from a fairchild lm386 data sheet and modified it a little. I have been able to pick up transmissions from a transformer coil.
