I'm experimenting with the highest octaves of CAFL frqs for TB possible to run on the F165. I get that 229Hz is one of the most effective. I felt it the most when I first started treating my SD with FreX.
So, I've upped it to 13711178.45277780 Hz and ran for a bit. Got a weird sensation in my crown chakra. Never experienced that before. Very noticeable. So, I kept running the frq till the feeling subsided and went away.
