Anyone out there help with suggestions?

All I get is some bleed-over from an FM broadcast station. Cannot
even get NOAA weather (162.40), where their tower is on top of
adjacent mountain, maybe 2 to 3 miles away!

Did my front-end die or what?

NG on local HAM repeaters either. I always was able to get both with
mo problem!

I did reset with internal button, before that nothing would come on at
all (and yes I have fully charged NIHM's installed (is the NIMH
voltage too low?)

Also tried 9V wall wart, bleed-over came in stronger. It almost seems
that the frequencies are gone.

HELP!

I used to have a Pro - 37, and I had problems with corrosion at the
antenna base,( in side the scanner at the place that the wires that
connect to the circuit board) and also corrosion on the pins where the
two circuit boards attach to each other. The local FM maybe
"overloading" your scanner "front end", this causes distorted
reception, but no reception of the frequencies that you are tuned to.
Are you still getting a frequency readout on the LCD? So try to see
if you have any corrosion (like I had). If you do not want to take
the scanner apart yourself, you may be able to get a radio repair shop
to do it. If no corrosion is found, then maybe someone else on this
newsgroup can help with better suggestions.

I'm not real familiar with that unit, nor do I have a schematic for it.....
There are reference crystals in there, perhaps one of them went bad. I DOUBT
that unit has a lithium memory cell in it, but if so, maybe it is bad. Does
it show in scanning or manual mode, any frequencies you've had stored in?
Don't depend JUST on NOAAs transmitter as a test.. Though it should be a
good one, they may be having a problem or there could be something impeding
the signal to you from them. Case in point, our NOAA tx used to come in real
well. As of late, it doesn't. There are spotty areas that weren't there
before.
So, try a local frequency.... as a secondary test. As the gentleman stated,
your antenna connections "may" be bad.Then too, the RF Amp or IF amp could
have went bad. Things do happen when not in use. Could be bad solder joints,
bad caps, bad crystals... etc.

Thanks guys,

I have opened the unit up (thanks to disassembly instructions for a
mod that I found when doing a "Google" for the unit) and everything
looked OK as far as no corrosion as far as I can determine.

There are no programmed frequencies left after doing a "reset" with
the internal reset button, however I was able to program some
frequencies (including the NOAA ones) into the unit. I tried scanning
and nothing caused the scanner to stop on a station, which is VERY
unusual.

By the way, I have a NOAA (Midland) emergency radio - including
regular weather forecasts - in the same room and it is OK, no problem.

This leads me to believe that the frequencies that I see are NOT the
actual frequencies, otherwise I should get something (I would think).

Maybe a crystal is bad (there are two on the top board) but I do not
have a schematic, but a parts list is available through Radio Shack.
Not sure where the parts are available from, especially in ones or
twos. Parts places usually want to sell 25 or more at a time.

I hate to take it back to the "Shack" and have them tell me that parts
are no longer available, OR that it will take a bank loan to afford
the repairs!

Thanks for your suggestions fellows, maybe someone can recommend a
good repair person who doesn't charge an arm and a leg to look at it.
I am retired and must watch where I allocate my retirement monies - of
course that is true even if you are still working!

I was unable to check for replies until now (busier that when I was
working), so my reply is a little late to both of you. As I said,
thanks for the recommendations.

Not sure exactly sure if it is worth the scanner being repaired or not - may
not be economically viable, but there are some reasonable pages on the net
(below) that may be of assistance in helping you to fix the problem. I
suspect that unless you can find someone who does repairs for the enjoyment
of it rather than for a living (there are some of those around, but few and
far between), it would probably be cheaper to replace your scanner than fix
it.

Matt,
Thanks for the links. I knew about the RS one, bit the other has a
multitude of other helpful info about repairs, Used and new units "on
special", so I may look into another one from the site owner (and
repair man, etc.). His basic repair rate for my type is $45.00 plus
parts and he wants an email with a description of how it is acting
before he will accept it for repair PLUS there is a 4 to 6 week
turnaround! WOW, maybe I should buy one of his $99.99 specials!

I am bookmarking the site. Maybe I can get a couple of bucks discount
by sending him my old one! - He is looking for a PRO - 39 and 43, so
maybe he will take my '37.

Hey, thanks again Matt.

No problems Juny, unless I have a radio that is definitely worth it, I do
not send them to the average repairers, but fortunately I have a couple of
contacts who actually do repair work for free (or a case of beer) and I have
also learnt by trial and error how to fix some of the problems myself. With
an older scanner like yours, I would probably cut my losses and upgrade
(always a good excuse).

Cheers
