John, a ham friend of mine had one of those bearcat scanners and 
as I remember, they ran very warm temperature wise and also had a 
lot of synthesizer noise.  The Regency model ran much cooler and 
as I recall, didn't have nearly as much background noise on 
signals.  Jim WA6EKS

Hi Jim, I remember that scanner, it was a hot receiver, as I 
recall!  I
also had a Barecat 101, or 100, that used the same idea, but was
programmed with the 16 channel lock-out switches on the front, 
and had
one of the hottest receivers I have ever seen in a scanner!  I 
used to
know the formula to convert the frequency to that binary number, 
so I
could make the scanner go to frequencies that weren't listed in 
the book!
