Extending Frequency Range

be slightly more difficult to get on and off because you will lose some rigidity

provided by the window, but you will have free access to the buttons and display.

If you reverse the carrying strap hooks, the case will be considerably easier to get

on and off.

Extending the frequency coverage

The AR1000 is microprocessor based and the parameters that determine its

coverage are set under software control. If you have an older model AR1000 that

doesn’t have continuous coverage from .5 MHz to 1300 MHz, you may want to

perform this mod. This mod will also reset your unit if you’ve locked it up by

entering in too many “cleared” channels. You should be comfortable with solder-

ing and with working inside electronic devices if you are going to perform this

mod. Also be aware that this procedure will clear out all of the memory channels

in the AR1000.

To do this procedure you need:

• A small Phillips screwdriver

• A small slotted screwdriver

• A soldering iron

• Needle-nose pliers

Here’s how to do it:

1) Remove the batteries.

2) Disconnect the antenna.

3) Pull off the tuning, volume, and squelch knobs. Be aware that there is a small

washer that sits between the volume and squelch knobs.

4) Remove the four screws that hold the case together. Two are in slots on the

top back of the unit and two are near the bottom in the battery compartment.

5) Unplug the battery connector.

Lay the scanner face down (keyboard and display) on the table and the antenna

connector to the top.

6) Unsolder the black wire from the lower right corner of the top board.

7) Unsolder the brown wire from the upper left corner of the same board.

8) Remove the three screws on this board.

Gently pull this board down and out. The volume, squelch, and tuning knob will

come out with it but not the antenna connector.

9) Unsolder the black wire from the upper left corner of the middle board.

10) Unscrew the brass standoffs that hold this board.
