check to see if the pin on the antenna is broken off. take the antenna off and look inside the bottom that goes to the radio and check to see if the pin is still there if not it is probably broken off inside the antenna jack. also check to see if the squech knob is not turned all the way to the right. if so turnit back to the left all the way. you should hear sounds.

How do I adjust squelch. Squelch is locked on


I suspect you have it in the continuous monitor mode so follow the directions for getting back into the automatic squelch mode.

AUTOMATIC SQUELCH: The FRS is equipped with an automatic squelch circuitry filtering out weak transmission and unwanted noise, usually caused by terrain conditions.

MONITOR:
- This feature turns off the automatic squelch feature, either momentarily or continuously. It helps in receiving signals to its maximum range, but may pick up static signals, too.

Momentary monitor:
- Press the MON button; the monitor symbol will appear.
- Release the button to restore the automatic squelch.

Continuous monitor:
- Press the MON button for more than 2 seconds until a beep sound is heard. The monitor symbol will appear.
- To restore the automatic squelch, press and release the MON button again.

NOTE: You cannot transmit when the Monitor feature is activated.

This comes from the manual I found on-line at:

Cobra PR4750WX - how do I adjust squelch?


You are right there is no adjustment. You can however turn the squelch off and this maybe what is happening to you.
To turn the squelch off you press and hold the button that is just below the push-to-talk button for at least 5 seconds.
To turn the squelch back on, you either press (less than 5 sec.) and the same button or change channels.
When talking with a specific party or group, you should use the tone coded squelch (CTCSS) and that will mitigate the noise if you are not already doing that.

Scanner will not move from the programmed Police channel


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

Squelch when keying ptt


I would check my ptt wiring making sure the button is set so that when you push it it switches you from RX to TX. If you have a wiring diagram that would be helpful if not are you able to get one? In any event make sure the wires are not misconnected.
