The biggest hand wave of all is you saying at one moment that there are no resonances in the Sun lasting more than 5 minutes, then in the next moment invoking a 120 year modulation of a ~ 11 yr «dynamo cycle» in order to be able to claim that the other peaks in the spectrum at 9.93 and 11.86 are just sideband
harmonics of the 120 yr and ~ 11 yr periods and only coincidentally the orbital period of Jupiter and the tidal period of Jupiter and Saturn's
synodic cycle.
