Enabled full 806-960 but lost some key functions
Rad.Shack Pro 2032 (GRE) - manuf. date: 7/93
All the mods floating around I've tried for this scanner have not worked. I ended up just snipping jumper (JM69) and it enabled full 806-960mhz.But that disables the "0","." and "enter" key on the keyboard. Anyone have this model and successfully enabled 800mhz without losing any keypad funtion? I'm Halfway there....as soon as I figure it out I can put it back the way it was. Anyone with experience with 2032 mods plz reply! thx in advance
Mods that failed:
1) Cut the lead on the anode of D35
2) cut jumper JM69 in half
3) solder a wire between the anode of D35 and the side of the jumper
closest to
the label for JM69.

-------------------------
Required equipment...small-tip soldering iron, small gauge rosin core
solder, desoldering wick, Phillips screwdriver, 1N914 or 1N4148 diode.
1. With the scanner unplugged from power, remove both upper and lower
covers (foru screws in the rear of the cabinet), taking care not to damage
the speaker wires.
2. Set the scanner upside down with the back facing you. Locate the
microprocessor shield (upper left corner near volume and squelch controls).
Unsolder and remove the shield.
3. Refer to the diagram and locate the three-legged diode at the lower
right of the microprocessor chip. Carefully unsosolder and remove this
diode.
4. Referring to the diagram, place a 1N914 or 1N4148 switching diode
across the solder pads as shown. (NOTE POLARITY) Remove any excess leads
and carefully solder it in place. Be sure it's leads will not contact any
other components, paths or the reassembled shield. A small piece of tape
may be used as insulation if necessary.
5. Plug the scanner into power, turn it on and test the unit by entering
any frequency that may have been blocked in the 800 Mhz range.
6. If successful, unplug the unit and reassemble the scanner.
