Anyone here with "in-depth" knowledge of the Bearcat 250 Scanner and
repairs? I am way out of tune with these things. Haven't seen one - let
alone worked on one for close to 10 years if not much longer. I have a model
here just came in the door for repair. I've had a manual from days gone by.
There appears to be some differences - not shown in the manual. I'm
wondering if I can pick someone's brains about this model or it's
differences.

1. Was there more than one version of service manual? At the time I
purchased this, I don't believe I was told of anymore than the one - I
usually ask about revisions.

2. Did the updates in this model produce differences in circuitry (I'm sure
they probably did) - and how?

3. The issue I "currently" see - is I have "low level" audio, no squelch
action, no receive, no display, no dot. I started troubleshooting it and
this book has a Q206 listed in it as providing a particular voltage to the
circuit (can't recall which part of the circuit - without the book in front
of me). THIS unit shows NO Q206 where the book shows it to be. I can be more
specific in parts layout in that area if someone asks - but for now - I'm
missing some voltage and need to find out why Q206 is not there OR whatever.
The "Q204" is putting out like 4 - 6 volts less than it should. I'm not sure
that is the "only" issue here - but the first I found thus far. I'm just
trying to clear up the mystery of Q206 for the moment. The book shows it
"supposedly" on the "Features" board. Along with that issue, there is in the
same leg of circuit - according to my manual - a 47K ohm resistor there tied
to Q204 and a wire coming from the 18V supply - with an 9v Zener in that
area also. This model has a 1xxxx ohm resistor there OR at least it appears
to. It is burned in the center from heat - but the first band is clearly
"brown" - so this isn't the 47K as called for in my manual. Basically, the
circuit leg is all there - minus Q206! There's not even a place for it "to"
be, from what I'm seeing.

IF I'm in error of voltages/values specified - its' only I'm going from
memory - the book is in the shop - but I"m not off in my description
otherwise.

I can provide more specific info such as Serial Number, Board numbers and/or
revisions, whatever - if requested, I just don't have it in front of me at
the moment.

I realize some parts of this radio are impossible to get now-days - so - I
want to make sure I can trace this down to something repairable and get it
done OR find out quick it isn't possible and hand it back without wasting
much more time.

Any info? Please answer here - my address is a spam catcher only.

Thanks,

Lou
