   While tuning around on my ICOM R-7000 receiver last  Sun-
   day,  I  came  across  an  odd signal on 171.125 MHz.  It
   sounded like the banter of a teenaged boy and girl.  As I
   listened  more  closely,  I  could detect music and other
   conversation in the background.   Somebody  mentioned  an
   Oswego florist.

   The signal was transmitted continuously, unlike the  back
   and  forth transmissions in a two-way radio conversation.
   Was this a "bug" planted by some cloak and dagger federal
   agency?  A maverick cordless telephone?

   I phoned another radio enthusiast friend in town  to  see
   if he could hear the signal, but he wasn't home.

   Being a curious guy, I hopped into my truck and  program-
   med the mobile Bearcat 260 scanner.  My mobile antenna, a
   19" whip inside the truck, isn't  very  sensitive.   Even
   so, the signal got stronger as I drove the 1.5 miles from
   my house into Oswego (Illinois).

   I found the source of the signal after a few  minutes  of
   driving  around town, and listening to the activity.  The
   mysterious signal was from a  wireless  microphone  being
   used  for  a play at Oswego High School!  More tuning the
   next day uncovered 2 other Oswego  High  School  wireless
   mike frequencies:  170.225 and 171.825 MHz.

   A word to you security-minded  types:   If  your  company
   uses  a wireless microphone, then your competitors are in
   a position to say "We hear you!"
