	My cheap push-button phone would let out a half assed
ring now and then, last summer, when I was in New Jersey.  Have you
tried a different phone?

	Being bugged:  I understand that there are numbers that
you can call that will give you a rising tone that either stays high or
drops low and starts rising again depending upon whether there are
any extra listeners.  I've tried the numbers with different, but consistent,
results from different a variety of places.

	I used to have a list of four such numbers and I used to know
which response meant the line was "bugged" and which one meant not.
Obviously, these sorts of detectors can't detect everything.  E.g., to
the best of my knowledge there's now way to tell whether a satallite
signal is being received by an extra antenna either near the satallite
Or near the receiving ground station.
