Answer by richard1941 for Why does this AM radio circuit not work?
For this kind of radio, you need a BIG antenna**, try for 100 feet of wire as high as you can get it, perpendicular to power lines if possible. Also, you need a good ground. Multiple earth ground rods...

There was too many signals interfering with the radio. I was very close to the internet router. When I moved to a different room it worked.

Here's a conventional schematic.A 60' long, 30' high horizontal wire for the antenna and a buried water pipe for the earth connection, are a must. So is a germanium diode.The coil may be wound on a 2"...

With components of 1 mH and 20 pF, the minimum frequency you'll be able to tune is about 1.125 MHz. And that's neglecting the self-capacitance of the inductor, which is probably quite significant.For...

I made this back in 6th grade, about 1969. Make sure the diode is germanium. Add a 10k resistor as a load if no headphones in use. Use a long wire (several yards if possible) for antenna. When working...

It will "work"- in the sense that an AM radio station will be heard- if the RF signal is large enough.Use a good antenna, and live close to a radio station. And tune to the station.
