Hello, I have built a radio using the crystal radio circuit and it worked, but many of the stations overlap (you hear one with another in the background) and there is a very loud fuzz sound in the background of all the stations. I am trying to build it for my brother's birthday. If anyone has any ideas on how to stop the stations from overlapping and stop the "fuzzing" please help! Thanks in advance, Jeff V. | ||

Try it outside, away from computers and other electronics that produce interference. You can trade loudness for selectivity by using the trick we use for the 10 minute radio. Wrap a wire around the coil, and connect it to the antenna and ground where the coil used to connect. | ||

Thank you very much for your help and responding is such record breaking time, WOW!!! I also have one more question, is it possible to make the radio with two capacitors instead of a coil and capacitor. Thanks again, Jeff V. | ||

No. You need a resonant circuit, as described in the Radio chapter. You might want to read the entire chapter, as much of the discussion in any one project can help elucidate issues in another. |
