Check the Standing Wave Ratio(SWR)
Inspect the tightness of all electrical connections.
Inspect the antenna coaxial cable for wear or breaks on the shielding
Inspect the tightness of all screws and other mounting hardware.
Troubleshooting: Should the unit malfunction or perform poorly, follow these procedures; If the transceiver is completely inoperative…
Check the power cord and fuse.
If there is trouble with receiving…
Check the VOLUME control setting. Be sure the SQUELCH is adjusted properly. Possibly the radio is over squelched.
