Squeak in cabinet

[patticake]

We had a part time rattle/noise for several years. It sounded like someone was knocking on the floor or cabinet. Could not pin it down. Was on the roof doing something and noticed what appeared to be a shiny spot under the fold down antenna tip, put a piece of Styrofoam under it and never heard it again. I guess when the antenna was down, it would move and hit the roof.
Ernie, when I go to your place this year, I'll bring a good listening device, maybe we can pin it down to a specific area, like where in the wall we thought it is in.
