mcfriendly spake thus:

Do a search for "Wireless Doorbells" - lots of good choices and less
expensive than the time it takes to find the problem.

Except that it is possible that one of your neighbors might have one
that uses the same frequency, resulting in your doorbell ringing when
someone pushes their button. These are generally cheap looking and
sounding pieces of crap anyhow; real (hard-wired) doorbells are much better.

"In 1964 Barry Goldwater declared: 'Elect me president, and I
will bomb the cities of Vietnam, defoliate the jungles, herd the
population into concentration camps and turn the country into a
wasteland.' But Lyndon Johnson said: 'No! No! No! Don't you dare do
that. Let ME do it.'"

- Characterization (paraphrased) of the 1964 Goldwater/Johnson
presidential race by Professor Irwin Corey, "The World's Foremost
Authority."
