Not sure if this is an appropriate question for this forum but here it goes. New to electronics. Just built an Elenco FM scanning radio. Ovrerall build went well. When I finished and turned it on all was well. Wen I hit the scan button it did lock on a channel and I could hear music but there as a TON of static. it is like this on every channel. I played with separation of the copper coils (the fractor?) which changes the frequency hertz the radio range the radio scans. I am sure it could be a ton of things but any thoughts/ideas would be appreciated. Thank you.
The TDA7088 IC circuit in an Elenco FM radio kit is junk. I think the Philips old TDA7088 IC is not made anymore, Maybe only Chinese copies.
Years ago I bought a tiny FM radio using the same circuit for $1.00 at The Dollar Store. It produced interference and did not pickup any fairly distant stations. It picked up a few local stations at the same time.
A REAL FM radio does not pickup interference and does not play more than one station at the same time.
Turn off all power in house (assuming radio is battery operated) , then start breaker by breaker
turning back on. Fluorescent lights as Externet mentioned, ethernet cables, light dimmers,
generate large amounts of RF noise.
The simplest thing you could try is a longer antenna, and to "gound" not your antenna but the "ground" (negative/minus of the battery connection point to the circuit). The antenna should also not be a very thin wire.
Good luck.
It's a bad design using a cheap (bad) chip. Don't waste your time trying to reduce static by a few percent - static will still be terrible. The project is intended to teach you how to follow assembly instructions, read schematics and solder - it was not designed to be used on a daily basis.
