ok i just picked up a Uniden BC890XLT and was wondering on what i can do to this baby was reading about restoring 800mhz on it but took a peek inside and im a bit confused on the info i have found BC890XLT Subject: bc890xlt-800mhz full restore 1. remove all cabinet screws. 2. remove 4 face plate screws and 1 bracket screw at center of main board. 3. carefully depress the outside edges of faceplate shield and tilt down. 4. unplug j4 and j5 and ribbon connectors j501 j502 and j503. 5. remove faceplate and logic board. 6. position board so microprossoe chip is on left and memory battery on right. 7. locate the 3 chip resistors at chips upper right..marked 104 and carefully desolder. 8. install the chip resistor at the 2 empty pads closest to memory battery. 9. reassemble carefully in reverse order. 10. test by entering freq. around 870 mhz. my problem is i found the 3 chip resistors np but cant figure out #8 do i reuse a resistor i took out. and i cant figure out where the 2 empty pads closest to memory battery are any help ?
