Bearcat BC890XLT repair
in [Repair]
|
From: John KB5AG on 6 Mar 2005 22:17 I have a Bearcat BC890XLT scanner which seems todo most everything normally except receive anything. Inside, there's a Sharp switching regulator IC, an IR3M03A, which is running very hot. I'm not sure what this IC is for, since most of the radio is powered from the 5v and 8v linear voltage regulators on board. Does anyone have experience with this? I don't think Uniden sells service manuals any more, since the Govt. is sure we'd all modify our scanners to evesdrop on Politicians making illicit deals over their cellphones. Is there a schematic on line anywhere? Thanks, John

First off, look at http://repairfaq.ece.drexel.edu/REPAIR/F_BC_Repair.html . I was able to obtain a repair manual for an older model Bearcat (BC-220) from http://www.sarrio.com/ ; he might have one for your radio. You might also ask over in rec.radio.scanner . Good luck!

From: DaveM on 7 Mar 2005 18:16 Some schematic diagrams may be obtained from Uniden/Bearcat's parts department, (800)297-1023. Uniden currently charges a flat rate of $54 for scanner repairs. They will repair and return "out of warranty" items without an estimate unless the repair charges exceed the flat rate charges. The phone number for repair is (800)297-1023, too. I recommend you call repair before sending the broken scanner. Uniden America Corp. 4700 Amon Carter Blvd. P.O.
