Maximizes the tuning of the bandpass filters for weak signals. Common Troubleshooting Scenarios

Trace the 13.8V line on the main schematic directly to the power switch circuit. Check the reverse-polarity protection diode (often a large surface-mount diode near the power lead input). If the radio was connected backward, this diode shorts to blow the fuse and protect the internal ICs. Issue B: Low or No Transmit Power (TX Failure)
