This is my old scanner that I havent used in years. Still works great, besides that the battery doesnt hold a charge longer than 30mins. It runs forever when plug in. This is a very good scanner here are some specs-

* 200 Channels - scanning capability split into 10-20 channel banks. All channels are programmed through the numeric keypad.
* 11 Band Coverage - includes aircraft, all public service, "Ham" federal, military and police land mobile.
* 10 Priority Channels - the first channel of each bank can be selected as priority channels to be monitored every 2 seconds for important transmissions.
* Detachable, Rechargeable Battery - battery pack includes an AC Adapter Charger.
* Scan Delay - Add a two second delay to any channel to avoid missed transmissions or call backs from dispatches
* Automatic Search - Search for new active transmissions to add to your scan memory in any of the bands.
* Illuminated Display - Large LCD shows the current frequency and channel, as well as other operating features and modes.
* 7.2V rechargeable Nicad. Battery
* Serial # 45031486

Comes with 2 books with all kinds of emerency frequencies all over the country. Its one of the last scanners made that can pick up cell phone calls.

UNIDEN/BEARCAT 200/205XLT TEST MODE

by Bob Parnass, AJ9S

According to the Uniden/Bearcat 200/205XLT Service Information Manual, the
following procedure will load channels 1-25 with various test frequencies, and
zero the remaining 175 channels:

1. Press and hold three keys: 2, 9, and MAN simul-taneously and turn
the power switch on.

2. Set the power switch to the off position.

3. Repress and again hold three keys: 2, 9, and SCAN simultaneously and
turn the power switch on.

BC200/205XLT CELLULAR RESTORATION

Note: It is unlawful to monitor cellular telephone conversations. It is
possible to monitor signals from the deleted ranges even without conversion.
Simply add 21.7 MHz to the deleted frequency and enter the higher (image)
frequency. Reception is virtually identical in strength to that which would be
heard on the deleted frequency.

The frequencies deleted at the factory may be restored, but the
procedure must not be attempted by anyone unfamiliar with electronic
circuitry. Grove Enterprises assumes no liability for damage caused by
this procedure. (I won't eighter! WA2ISE). The modification will void
your warranty.

BEARCAT BC200/205XLT SCANNER MODIFICATION

RESTORING THE DELETED 800MHZ BAND OF YOUR BC200/205XLT CAN BE
ACCOMPLISHED EASILY BY LOCATING THE MICROPROCESSOR LABELED,"UNIDEN UC-
1147". ONCE YOU'VE IDENTIFIED THAT IC,LOCATE THE 10K OHM RESISTOR
(BROWN-BLACK-ORANGE) POSITIONED ABOVE THE LETTERS "DEN" ON THE IC. THE
RESISTOR IS LEADLESS,SO TO ACCOMPLISH THE MOD,SIMPLY CUT THE BODY OF
THE RESISTOR IN HALF. USE MINIATURE WIRE CUTTERS.

DO NOT DISTURB ANYTHING NEAR IT. IF THE LEFT SOLDER PAD COMES LOOSE,IT
MAY BE PEELED FROM THE BOARD. BRUSH OR BLOW AWAY ANY RESIDUE.

NOTE*** IT IS UNLAWFUL TO MONITOR CELLULAR TELEPHONE CONVERSATIONS

73 DENNIS WB2WPO @ KE2KQ HUNTINGTON NY (ZIP 11743bc200xlt.4

TOOLS REQUIRED: Small Phillips screwdriver, small wire cutters.

1. Slide off the battery pack and remove the antenna from the scanner.
2. Using a small Phillips screwdriver, remove the two screws from the
back of the scanner, the two screws which hold the battery
retaining spring at the base and the spring itself.
3. Carefully pry the bottom of the rear cover from the radio and
remove the cover.
4. Locate the two small screws at the base of the circuit board and
remove them. Gently pull the front panel from the mainframe at the
base and separate them.
5. Locate the (64 pin quad flatpack) microprocessor IC labelled
"UNIDEN UC-1147" and the 10k ohm (brown-black-orange) leadless
resistor positioned above the letters "DEN" on the IC.
6. Using miniature wire cutters, cut the resistor body in two without
disturbing anything else near it. If the left solder pad comes
loose, it may be peeled from the board. Brush or blow away any
residue. This completes the restoration.

Restore the Cellular Freqs. on Your BC200/205XLT!

This is so simple that anyone can do it, and you have to be
REAL sloppy in order to damage your unit.

There is no soldering involved, but if you do happen to mess your
unit up: YOU AND ONLY YOU ARE THE ONE THAT IS RESPONSIBLE. We take no
responsiblity for any thing that might become of you or your radio!

This mod. will also void your warranty, so open your radio and
check it out to make sure you can pull it off before you begin the real
work.

Now that we are through with the usual backwash of "spooky"
information we can now begin.


1.) Take the antenna and battery pack off of the radio.

2.) With a Phillips-head screwdriver, remove the two screws at the
back of the radio. Then remove the two screws and the battery
spring at the base of the radio.

3.) GENTLELY! pull off the back of the radio.

4.) Locate the two screws at the bottom of the board, and
carefully remove them with a Phillips-head screwdriver.
(Be carefull not to damage any of the surrounding components.
This is not to tough to avoid, but warrants mentioning.)

5.) EVER-SO-GENTLELY! pull the front panel away from the scanner
frame.

6.) On the front panel part of the radio, locate the microprocessor
IC (labeled UNIDEN UC-1147, its the biggest black chip on the
board) and the 10K ohm (brown-black-orange) resistor positioned
right above the letters "DEN" in the word "UNIDEN" on the IC.

***** MAKE SURE YOU LOCATE THE RIGHT PART *****

7.) With a small pair of clippers, clip the resistor right in two.
Make sure not to disturb any components around the resistor.
Leave the ends of the resistor on the board, all you need to
do is just clip it enough so that there is a gap between the two
ends. Take care to clean the remiments, made by cutting the
resistor, of the board.

8.) Check to see that there is no damage and everything is tidy.

9.) CAREFULLY reasemble the radio in exactly the reverse order of
how you took it apart. Be careful to line up the pins to their
sockets in the lower, left-hand side of the radio.

***** FAILURE TO DO THIS CORRECTLY WILL RESULT IN A DISPLAY
ERROR. WHEN THE RADIO IS TURNED ON NOTHING WILL APPEAR ON THE SCREEN.

don't panic.
I've done this before. The malfunction can be fixed by taking
the radio back apart, carefully, and making sure those pins are
in the correct socket. I almost gave birth to a small cow when this
happened to me and I was very relived to find out that this was all
that was wrong.

10.) After you have tightened the screws, put the battery pack and
the antenna back on the radio. Then press "MANUAL, 845.0, E".
Within two seconds the freq 845.000 should pop up on the display.


Now you have completed the mod. for your scanner. I would now like
to welcome you to the world of the forrbiden freqs.! You will now
see the truth to the statement "Never say anything on a cellular
phone that you do not want anyone else to hear." Unfortunately
(but fortunately for us!!) there is an incredible number of people
that do not know this and you will be suprised at the information
broadcast across the airwaves.

Enjoy!

Andrew, I wanted to let you know I received the scanner in great shape. Thanks for the extra stuff too.
I was able to have a local battery shop rebuild the pack with a 1000 mAh battery. I don't know how long a charge lasted when the radio was new but with the new pack takes about 16 hours of on time to run down.

Thank you
Chris
