>      Several weeks ago,	I posted an article in which I	told

>      tions on my 800 MHz television set.
> 
>      Here are some excerpts from  a  letter  to	 the  editor
>      appearing	in the May 1985	issue of Personal Communica-
>      tions magazine:
> 
> 	  "In reference	to your	March 1985 article on cellu-
> 	  lar  privacy,	 I  have  developed  a technique for
> 	  eavesdropping	on cellular users that	requires  no
> 	  fancy	  scanner,  no	computer,  no  sophisticated
> 	  antennas or any other	gimcracks....."
> 
> 	  "....By using	the manual tuning  on  the  varactor
> 	  tuner	in my VCR I have little	difficulty listening
> 	  to the neighborhood cell sites on  my	 1973  model
> 	  Zenith  TV....   Since  sidetone  is transmitted I
> 	  hear both ends of the	conversation....."
> 
> 	  "Handoff is an irritation,  but  frequently  I  am
> 	  able to manually sweep across	the band and pick up
> 	  where	they left me.  What really irks	 me  is	 the
> 	  low  audio  level from the TV	due to the deviation
> 	  mismatch."
> 
> 	  "The real significance of all	this is	that  anyone
> 	  with	a  TV  and VCR connected to a TV antenna can
> 	  get the same results with a little practice...."
