It is very likely the PC you are using does not have enough speed and/or RAM capacity for supporting your RSP receiver. As a minimum guideline you should use a PC with a dual core 2 GHz processor and a RAM of at leats 2.5 GHz. With these minimum requirements you will be able to open just one VRX.

The USB cable connecting PC to RSP receiver is a critical component: it should be a quality cable with double shield and ferrite suppressors at both ends.

Furthermore you should shut down all other applications while you are using SDRuno.

For more info you should state what PC, what processor, what RAM and what operating system you are using.

Hello Leon,
ADC overload indicates that your gain is too high and you risk overloading the ADC. This will not cause any damage, but will lead to intermodulation and poor performance. Firstly, ensure that your IF AGC is enabled and then if the message persists, reduce the RF gain (or increase the RF attenuation).

Sincerely
