Sensitivity Issues
If you notice poor sensitivity, noisy RX, or other receive issues, try opening the radio and tightening the screws holding the boards to the chassis. In some cases the boards will loosen to the point where they do not make good contact with the metal body, reducing the RFI shielding ability and increasing noise in the receiver.
