Avoiding Front-End Overload
If you are tuned to the HF bands and the S-meter shows the words ADC CLP,
the analog-to-digital converter (ADC) is overloaded (i.e. clipping the signal). In
such case, use the Attenuator to reduce the level of the signal entering the
ADC. You can use the Auto button which reduces the signal automatically to
the optimum level. The attenuator is only applicable for frequencies up to 50
MHz.
If you experience any installation problems or are unable to tune to any radio
stations at this point, please refer to Appendix B - Troubleshooting.
Should you encounter interference-related problems with your receiver,
effective remedies do exist; please peruse Appendix D – Dealing with
Interference.

Did you know?
Excelsior (“ever higher” in Latin) is the official motto of the
State of New York, and is featured in its Coat of Arms and
the State Seal.
Liberty and Justice support the shield and the American
eagle spreads its wings above on a world globe. Justice is
blindfolded and holds a sword in one hand and a scale in the
other, symbolizing impartiality and fairness.
