CB stays on RX - never goes off. Squelch is set at mid-point. Can you explain why please?

The AGC ( auto gain circuit is possibly cranked uo too much and perhaps the squelch circuit needs adjusting also. If allelse fails trun up the sq. conrol. the local ( louder ) sIgnals will trigger those signals....The weaker (DX ) signals will be more difficult to hear unless the sq. is right off .

Squelch knob doesn't do anything.

Your SQ control is either bad or needs to be properly aligned on the circuit board. You can ship it in for repairs at

Squelch doesnt work

Open the component / speaker side cover on the radio, adjust VR3, this is the alignment control for the squelch. Set your squelch control knob on the front of the radio to about 10 o'clock and slowly adjust VR3 until the signal from the speaker is mute.

When you turn the squelch back to the 0 position, you should have signal with no squelch as in normal operation.

Squelch control on Galaxy DX-2547

You may have a bad transistor or detector diode that feeds the squelch circuit.If you can read a volt meter and Ohm Meter, and can solder ( Make your own repairs ) you may want to call Galaxy as the Techs there are normally very helpful.
