Help Uniden BC XLT 200

[Oguz Kaya]

hello everyone,
I am having problem with my BC XLT 200. It was working with no problem. I
didn't use for a while and next time when I turned on it seems like working
but scanner doesn't find anything. It keeps scanning. I did reset it by
pressing manual 2 and 9 keys but still the same. I think some how squelch
doesn't work. Even Wx channel doesn't work it keeps scanning. If any body
know what is wrong with it I would greatly appreciate it.

Thanks a lot.

The obvious first thing to check would be the attenuator setting (if it has
one); make sure its switched off. next would be the antenna connection... if
your using an external antenna check the connector for broken wires, if your
using a whip try changing it for a known working one (a bit unlikely but you
never know). Sometimes the centre pin of BNC can break off and get lodged in
the antenna socket so its worth having a look at that too.

i know this may sound stupid,but have you any freqs in the scanners
memory,as when you reset it would of emptied all that was in there.

what area are you in,there might be some freqs someone might know,that it
can be tested on.

regards Paul

I will check antenna connection. Thanks for the info

I GUESS I HAVE FOUND THROUGHOUT ONE OF THE NEWS READER, WHAT IS WRONG WITH
MINE HERE IS THE TIP;
Uniden/Bearcat BC200XLT Portable - Loss of Audio and Dial Lamp
If you can program frequencies into your BC200XLT but there is no audio and
the green backlight no longer functions, a tiny transistor may have failed.
Check for a defective PNP surface mount transistor, Q201 (2SB815B6-YDY).
Q201 is used as a switch to furnish 8 VDC to several stages of the BC200XLT.
Its main purpose is to switch off power hungry stages of the BC200XLT when
the CPU thinks the NiCd voltage has fallen below a threshhold. That's an
attempt to limit the current drain on weak NiCds to avoid permanent damage.

Q201 is located on the foil side of the "Micom" board, adjacent to the black
multi-pin connector which mates the Micom and main boards together.

Q201 can be destroyed by a few different causes, primarily, by something in
the scanner drawing too much current through it. In one case, capacitor C36
shorted. It's a 220 uF 10v electrolytic, located on the component side of
the main board, connected from pin 8 of the audio IC (IC2 NJM386SL) to
ground. Capacitor C55 shorted in another BC200XLT. Gary Bean reports he
substituted a 2SA1298 for Q201 and it worked fine. In a pinch you bypass
Q201 by soldering a short piece of bare wire between the collector and
emitter, but you must first fix the component which caused Q201 to fail
