memory loss. If memory is lost, simply reprogram each channel. The display shows "MEMO LOSS" when memory is lost. Always press each keypad button firmly ...

The Bearcat Scanner is neat hand held scanner, Is the scanner programed? Depress the WX for weather and see if the weather channel is available. The squelch knob should be turned clockwise and the noise level should decrease (actually you are decreasing the allowable signals to be received). If you get no response from a know frequency, then the squelch pot may need cleaning or replacement may be in order.....Cost for repair at service shop may not be feasible.

Hi,

Have you turned the squelch knob all the way in both directions, to see if that helps?

If so, then you have to replace that squelch knob unit, with a newbie.

I hope this helps.

Cheers,
Peter

Units that are stored for a long time may take some time (hours) if caps inside have gone flat from no use.

Uniden also has or had a flat charge for repair of these units--might want to look into that and weigh it versus the cost of a newer scanner.

try pushing you private button that you have you frequencies programmed into.this will scann your scanner. and then turn your squelch...

Try cleaning the knob, it may have dirt in the Volume,Squelch. Spray Tuner cleaner inside knobs (After removing knobs off top, may have to take off cover to do this) Make sure unplugged when cleaning it. Make sure speaker wires soldered good. Change speaker to new one --if possible. Get a outdoor antenna with a Booster for scanners. Try to see if antennuator is on radio..It may be switch that says 0db--10db selector. make sure its on 0db for indoor types...10 db for outdoors. Adjust sqelch until it stops hiss--keep it 2 notches above hiss for weak signals.

Rotate the knob counter clockwise to close the squelch. If this does not work, remove the knob by pulling it off gently and make sure the "pot" is turning with the knob. Verify the knob and "pot" are not damaged.

Look at the squelch knob. If it is turned fully counterclockwise, it is in "Auto". Turn the knob clockwise to enter the manual mode and adjust the range untill static is heard. Reverse direction until the static is no longer heard.

I have a couple suggestions for you. The unit has probably gotten oxidized controls from age. Any thing with rotating contacts over a period of time will get dirty. You need to purchase some contact cleaner (Read info on the can that it is safe for plastics) and flush the squelch and volume controls. You may also have to open the unit and identify what they call 'pots' or little trimmers to clean and adjust. Set your squelch control at mid range and with an insulated tool turn the pots a little in both directions and return it to original the positon. This will clean the control and when you find the one that effects your squelch it may have drifted and need to be readjusted until you have better control on the front knob.

L16 Disc coil needs adjustment, Audio is slightly off, and improper noise to DC squelch level detect used to stop scan on active channel. Set to an on freq signal like a NOAA weather channel, and useing a non-metallic tool, adjust to best sounding audio, probably less than a half turn either direction. An on freq signal moduated by 1000hertz, connect scope to speaker and adjust for highest undistorted recovered audio would be better if you could.
