Thanks, I'll have to check out Dr Ludwig. There is an extensive archive of Persinger's work in this field - we can now measure these very weak fields and have adapted/evolved to function in resonance with them. For example, at night the Schumann frequency profile shows marked resonances below the 7.8Hz - these coincide with brain frequencies that govern the phase-change between being awake and asleep. By swamping our air with pulsed microwaves that include low frequency components because of the way the packets are switched may make it difficult for some brains to "power down" to below 4 Hz.
I'll have a periodic dive into your old posts - see if there is anything I can comment on! :-)
