I discovered a couple of modifications for Bearcat 175xl.
On the CPU board there are 4 solder pads next to the CPU.  Shorting two
of them turns it into a 20 channel scanner (from 16 channel).  Shorting
the other two removes 29-54 and adds 66-82.  I can program 66-88, but
it will not receive 82-88.  But it receives 66-82 as well as my 2006.

I want to know however--how can I make it receive wideband?  I see
that there is this chip into which it seems a FM signal goes and
and audio signal comes out.  It is a Motorola mc3359p.  What is it?
Is it doing what it seems to be doing?  How can I make it work more wide-band
like?  I've tried adjusting values of all kinds of things around it with no
success.
