I have conected attenuating cable to the pc and scanner, but I have the same
problem. nothing but static. I played with volume all the way down and in
between. Also when I connect the attenuating cable to the computer I lose the
audio through the computer speakers.

Do you have any idea why I am having problems?

This sounds stupid but as an ex-computer tech-----Are you SURE that you are
plugging into the correct spot??

It should be going to the spot labelled LINE IN, if you are putting it anywhere
else you are doing it wrong. If you ARE doing it right then e-mail to me directly
and I will help you figure out the problem.

Yes ALL connections are correct and as far as I know all setting are correct
 in win95 8 bit mono record.
I have tried both a stereo/mono & attenuating cable. This is on a Sport Cat

Thanks for any input.

Do you know what kind of sound card you have in your computer?  Post the brand
and model.

Just hooked up a small utility battery (170 CCA) to power one of my radios here
in the house.  Radio draws about 7A peak on transmit, and this seems to work
well.  Planning on wiring in a trickle-charger (1-2A), and leaving it plugged
in to assure the battery always has a full charge.  Wal-mart sells these for
$16.95.  Apppears to be nothing more than a wall wart type power supply with

the same specs.  Can I simply cut off the plug, attatch the wires, and use
these?  Or is there something "special" inside the trickle-charger that makes
it more appropriate for battery-charging applications?

"Where's that big 'ol CB RAMBO??"
 "I wanna hear him TALK TOUGH!!"

Everything depends on the precise kind of battery
it is....and from what you said, I can't tell for
sure.  Sounds like a type of lead-acid battery, in
which case the maximum safe trickle charge is about
13.80 volts across a "12v" battery.

If you can regulate that power supply to 13.8v and if
it has the current capacity that might be required by
the battery, then it could serve a useful purpose.
So far, I've referred to the subject title, which
appears to not be related to the text of your post, though.

If you're asking if you can run a radio off a battery
that's floating on a trickle charger, then yes.  However,
of the battery drains say 5-amps on the average when
you transmit, and if the trickle is 1-amp max, then over
a period of transmitting, the battery will run down.

This brings up a subject we'll call "duty cycle".  If
the drain-to-recharge rate is 5:1, then over the long
haul, you have to allow for a minimum 20% duty cycle,
with 10% being best to assure long term health of the
battery.
