Hi Folks!
This past weekend (5/16/2004) I visited a local flea-market where
I found an AOR AR-2500 scanner/monitor. I figured the guy would want
$100 for it. Nope, he said he couldn't make it work and that numbers
only scrolled across the display. $4.00 (four dollars). "Sold!" It
has a power supply that looks modified as the cord appears to have
been cut and + and - swapped. All this heat shrunk. Inside the radio
there is a wire and transistor that appears to be connected to one of
the front controls. The transistor also goes to a connector inside.
The wire was loose on the control. All this also was heat-shrunk. I
put it on a lighter-jack after getting hum with the 300mA power
supply, and it seems to work OK! Lot's of intermod, however! There
was aluminum/vinyl tape over some parts, and I've just read in the
groups here that this might be factory! Might this transistor 'mod'
be factory, too? Also, there appears to be a brown wire cut out of
one of the harnesses. Other than this, it seems to be OK.
Anyway, is this transistor stuff a cellular mod? Is the 300mA supply
under rated? This scanner gets warm and must be drawing more than
300mA.
Some strange behaviors: There is an up/down knob. Turning it right
seems to raise the channels, and turning it left lowers the banks. Is
that right?
The down button seems to do nothing. Sel Bank button takes a few
seconds to work. There is a red line (marker?) through the delete
button and off the button to the side. Could all this be factory?
Thanks!
