Check the Ground side of the meter it is the only common point.

Re: Re: Cobra 140 gtl RF/Sig meter not working.

Check there is not an open circuit between the sig/rf meter and R203. If you check out the circuit diagram you will see that the only common connection to the sig/rf meter is ground, and check you have the wires on the meter the right way round.
