Irving is back in the LENR game it seems, here's a very recent paper with some (limited) info on superwaves, his magic method of triggering LENR. He shows it works for every system.
I suspect that this is two oscillator circuits with the lower frequency one stable and the superimposed peaks being driven by a second higher-frequency oscillator circuit whose output voltage from base to peak is driven and controlled by the instantaneous voltage in the first circuit.
I don't think it's a huge problem - in fact the double trace shown in this paper could almost be represented by a single trace.
