Just wondering, if you tried to do a re-set of the radio? I doubt that
would do anything, but it might not hurt.

I recently purchased a pro97 scanner in near new condition over the
internet
through ebay. The item was
listed as having very low audio such as one has to place the speaker next
to
his ear to hear the broadcast so I took a chance and bought it for 45
dollars. I got it in yesterday and it is totally new! packaging, all
accessories, books and not a scratch on it. Well. I unpack it and install
freshly charged (new) batteries and
I go to playing with it..first..a weather channel..sure enough, very low
volume even when cranked to the fullest
it is still at the same volume level. I went ahead and took out the four
back cover screws and examined the area
where the volume pot is soldered and took some readings. center tap is
about 2.1kohm and 200 k ohm on the non grounded side. (this is without
power
applied)
in the area of the volume/squelch pot, are 3 tiny pots
and 3 test points...(this is all from memory as the scanner
is closed up now). I was hoping for a misplaced speaker magnet or
something
simpler and the circuits are ungodly
miniature and even the audio amp chip is about the size of an op amp on
most
regular size circuits. The doggone thing is so new looking, that it may
be
swapped with a
newer one from radio shack (by swapping backplates) but I don't dare
attempt
the dishonest. Anyway, any suggestions to resolve my dillemma...could it
be
possible that I have a defective volume pot? No amount of regulation seems
to affect the audio at all. The channel
beep come through loud and clear but it seems that either
the preamp from the radio is set too low or the pot is defective/soldered
wrong. Of course, the possibility of
a bad IC has crossed my mind as well. Any suggestions?
No warranty so all I have is either a repairman or my good wits and some
knowledge to help correct the problem. Btw, the sqelch seems to work OK.

Your input would be greally appreciated,

Allen
