Regarding Doug Davis's comments, I am not aware of any scanner
receiver manufacturers that limit coverage in the 46-49 MHz region.

Also, Doug says that Radio Shack does not limit coverage in the 800
MHz celluar area on their scanners.  Not true.  They started blocking
these frequncies in their scanners even before passage of the ECPA,
although the radios can be modified back to full coverage.  Some
owners have reported that Radio Shack has refused to service these
radios after the cellular mod has been made!  The mod consists of one
clipped diode.

[Moderator's Note: Actually, one diode (from D-12, I think) is clipped
and re-inserted at D-9 to gain full 800 coverage as well as 68-88
megs.  Unfortunatly, the scanner loses 30-50 megs in the process; but
who cares?  And even losing 30-50, you can use the 'magic number'
calculation to bring 46.61 => 46.97 back at 68.01 => 68.37 and 49.67
=> 49.99 back at 71.07 => 71.39. The IF is 10.7; just double it (21.4)
and add to the desired frequency.  It isn't the best reception, but it
works.  PT]
