This Uniden Bearcat BC310A Scanner needs repair or is for parts. 

When it is plugged in it turns on but there is no sound.  There is a burned resistor next to the speaker connector (see photo, at end of arrow on blue tape) that is clearly scorched and this may be its issue.

I also tested the included Uniden power adapter and find that its output is 17.8 volts where it is supposed to be 12 volts.  This may be its original issue. 

It may have issues beyond the resistor and the over-voltage power supply.  I have no way of testing. 

Includes the probably defective power adapter and the antenna.  No operation/instruction manual or original box or anything else included. 

This is sold as not working, for parts or repair if it is indeed repairable. 

Quick shipping.
