 Interesting. Are these more or less permanent
 in these locations? Ie can they be relied on to
 deliver the signal at all times or most of the time?
 
 And what exactly are inversion layers?

 Locally, years back, police stuff was being
 picked up by baby monitors, quickly changed, which
 then resulted in the baby monitors receiving
 transmittions from taxis and pizza delivery
 drivers and suchlike. I remember sitting in the
 kitchen of my daugther's place and saying: What's
 the hell's going on in the baby's room!? I think
 they finally got that straightened out as well.
