Unfortunately I don't have any tools or anything, just the clocks.
Hopefully whoever is causing the interference will stop once the
holidays are over (I don't think it's me, as nothing has changed
inside the apartment). Even if I could find the source of the
interference, I wouldn't necessarily be able to force my neighbors to
stop whatever they are doing that causes it.
