Feb. 21 (UPI) -- An Illinois family said a wall in their 9-year-old daughter's bedroom has been picking up radio signals for years - and no one knows why.
Richard Smith said voices and music were repeatedly heard inside the wall in daughter Brianna's room at their Lockport home, and the family eventually determined something inside the wall was picking up a local AM radio station.
The station, Christian radio station AM 1160, owned by Salem Media Group, sent out an engineer to investigate, but was unable to identify the issue.
"He said, 'I got to be honest with you. I don't know what is acting as a speaker. There is nothing I can explain of why you're actually hearing it,'" Smith told WLS-TV.
He said the wall was opened up and the electrical grounding was examined, but the family was still unable to figure out where the radio station was being picked up.
"Sometimes when we think we've arrived at a solution, the next season comes around, and it's back," Smith said.
Household objects have been known to pick up radio signals in the past. A man reported in 2018 that radio signals were being picked up by the metal components in a household fan while the power was off.
