Cant stop squelch - Uniden BC248CLT Base Scanner

Your RF gain control needs to be turned all the way up to be able to receive signals and if you are on one of the HF bands like 40 meters or any HF band the squelch control needs to be all the way off! You do not use squelch on HF! When on VHF or UHF then you would rotate the squelch control just to the point that the background noise stops and go no further. Higher squelch settings will only block weak signals and your radio will be deaf! Squelch control rotated just to the point the background noise stops! NO SQUELCH ON HF. Turn the squelch all the way off on HF!

On all channels, or on one channel ? Some channels are "birdie" channels, check your user manual. Others are problem channels receiving false signals from computers, monitors, receivers, internet equipment, FAX machines, etc. If your in conventional mode, if in Digital mode the squelch is set by the processor, and I don't believe the squelch has any effect in that mode.

The squelch control gets rid of the hissing on a blank channel. Finda blank channel, turn up the squelch control until the hissing stops. The scanner should then scan the channels and stop on a busy one.

Plug the AC adapter into the back of the scanner and into a wall electrical outlet. Screw the antenna into the receptacle on the back of the scanner (extend the antenna to full length for best reception).

2 Set the squelch level to allow signals to be heard by turning the squelch knob counterclockwise. Rotate the volume knob clockwise until you hear static. Slowly turn the squelch knob clockwise until the static noise disappears.

3 Start programming frequencies into the scanner by pressing the "Manual" button.

4 Press the up arrow or down arrow key until the channel you wish to program is visible on the display.

5 Use the numbers on the keypad to enter the frequency for the local transmitter you wish to receive.

6 Press the "E" key to complete the process of entering the frequency.

7 Repeat steps 3 through 6 for each additional frequency you wish to monitor.

8 Press the "Scan" key to start the scanning process. The scanner stops on a channel when it detects a signal strong enough to hear over the squelch setting. Two seconds after the signal stops, the scanning process resumes.

If you haven't already done so, while scanning in the PRIVATE mode, turn the SQUELCH control down slowly until scanning stops and you hear a hissing noise. Then turn the SQUELCH up slowly until scanning resumes. This should set the threshold so that the scanner will stop on an active frequency.

If the weather band is working, the scanner should be working. To verify operation:

- Move the MODE switch to "Scanner" and power the unit ON.
- Press the SVC button (chrome button below display).
- Press POL (chrome button below display).
- Turn the SQUELCH knob towards the left until scanning stops and you hear a hissing noise.
- Turn the SQUELCH knob towards the right slowly until scanning resumes.

If the scanner stops on anything - even noise, it's working.

To Program:

- Slide the MODE key to "Scanner."
- Power the unit ON
- Turn the SQUELCH knob to the left until you hear a hissing noise, then turn it the right - slowly - until scanning resumes.
- Press HOLD.
- Press E (PGM).
- Press 0, 1.
- Press HOLD.
- Enter your first frequency, including the decimal point (EX: 156.055).
- Press the E (PGM) key.
- Press the UP arrow (above the SCAN key). Scanner will move to channel 02.
- Enter your second frequency, including the decimal point.
- Press the E (PGM) key.

You should now have two frequencies programmed. Press the SCAN key . . .

If it still will not accept programming, let me know.

you may need to play with the squelch. and/also hold down the light/key button until the key goes away but mess with the squelch after you get rid of the lock. you want the squelch as far left without it stopping and making static noise

Hello Are You using the correct antenna?,when you turn the squelch down do you hear static sound?, are you using squelch codes? if it is just a CB radio that works on Citizen Band (11 Mts) this radios does not have squelch codes.

Let me know the brand, model of the radio.

Do you hear the Beeps on the speaker? Check for the QT and the code squelch are the same in both radios, try to set code squelch in "0". Make sure that the radio is not receiving or the other one is not transmiting, with two radios will see the same.
