"b: Andrea might be afraid for feedback signals coming from the E-cat control box back into the grid,"
Exactly my thoughts. The trouble is even with a low-pass filter I think you might see the waveform of the control on the scope if it is RF. I've certainly seen this with HFAC without the scope even being connected. Rossi would probably have to do an NDA to allow a scope when the control is operating depending on what the control is actually doing. Best regards, Jack
