what actual signal strength (in dBm) causes the device to enter Overload mode
Remember, it is the total power going into the mixer or ADC which can cause an overload indication, not just the signals being displayed on the screen.??
It is good practice to check the power of an unknown source with a wideband power sensor.??
Appropriate high-, low- or bandpass filtering can also be helpful, not just for overload prevention but to avoid images/mirroring in Ultra mode.
