ADC Overload Indicator?
ADC Overload Indicator?
Is there an ADC overload indicator in SDRC ?
Re: ADC Overload Indicator?
I am not aware of one. And there is no good way to deduce it automatically with most ham price level A/D converters.
Of course, if you get into an overload condition it's usually very obvious from the spectrum display. As you change gain many signals will appear or disappear depending on the gain change direction. It's usually very dramatic.

The SDR-iq has a red LED for overflow.
Not so sure about the SDR-ip, it's out in the repeater shed acting as a server.

Re: ADC Overload Indicator?
Regardless. when you really go into overload the display very suddenly grows a whole lot of high level grass and spurious responses. Many ADCs will simply overflow the top bit of the number leaving you with a very low number that should actually have full scale added to it. When that happens the spurs happen.
