I recommend you call repair before sending the broken scanner.
Misadjustment of manual this pot has been the cause of "no squelch" complaints in two BC300s and manual a BC250 I fixed.
Gary unsoldered the burned out bulbs in his radio and replaced them with 12 volt Radio Shack bulbs 272-1092c).
As far as I can tell, the heatsink was radiating noise from uniden the logic board into the front end on the radio board, which ended up being manual just below the heatsink.Since the on/off switch is on the secondary side of the transformer, current flows in the primary as long as the AC line cord is plugged into an active AC outlet.Other Problems Complaints of low audio output and occasional microphonics in three Uniden/Bearcat 800XLTs were caused by a bad 47 ufd electrolytic capacitor in series between the external speaker jack and audio amplifier.About m aims to become the most comprehensive reference guide for ham radio equipment.Failure of IC9, the 9 volt NJM78M09A regulator in a BC800XLT is another cause of a blank display.One way to roughly estimate a radio's age is to examine the 4 digit date codes often stamped on the integrated circuits.Box 95002, fort Worth, TX 76155, if Uniden doesn't have a schematic, try obtaining a Photophacts from Howard Sams Publishing division of Prentice-Hall at uniden (800)428-7267,.That's an attempt to limit the current drain on weak NiCds to avoid permanent damage.Retrieved from " p/BC200XLT categories : Uniden Scanners, handheld Scanners, conventional Scanners, radio Models.Bypassing the TIP29 (a voltage regulator) with disc ceramics didn't work; using a smaller heatsink and an insulator fixed the problem." "There is also a 220 ohm 1/4 watt resistor on the logic board.As built, the BC220 logic board is grounded only through its mounting screws.Instant weather band search backlit LCD display keyboard lock, owner's manual, uniden pDF.In the BC220, Matt recommends adding real wire ground jumpers from the main board to the feature (logic) board to fix grounding problems.Some channels were not affected.PDF, Unknown size, click to download.Copyright 1999, Bob Parnass, AJ9S.It is also available electronically from the anner ftp archive on the official usenet FAQ library ftp:anner.BC9000XLT: Loss of Sensitivity John Ward has fixed two BC9000XLTs which suffered from "low sensitivity." He fixed the solder joint where the antenna jack connects to the circuit board.RL-1, the carrier activated relay manual inside the BC890XLT wore out. Open Resistor in BC140 manual Robert Casey fixed his deaf, 16 channel Bearcat BC140 scanner.
