Topband: 160 meter current-fed T antenna, where did I go wrong?

Hi Mark,
N6LF recently found that the optimum radial length depends on how many radials
you lay down. Check this out:

Thanks very much to so many fellow hams who responded to my original post!
Nice to know the fraternity continues to help those with questions.
This afternoon, a lovely fall day in North Carolina, I abandoned the voltage
T and decided to "man up" and put down 6 x 120 foot radials for the 160
meter 1/4 wave inverted L which I had given up hoping for. I already have 6
x 32 foot and 4 x 64 foot on the inverted L.
RF coming back into the shack has been greatly reduced. Remote tuner
working just fine. Looks like I am headed in the right direction. So far
that makes 2 wavelengths of radial wire down. Probably need another
wavelength.
Will listen tonight to see how things go. Anyone know where we are in the
"27 day solar rotation" which seems to affect 160 meters? Are we miday
through, nearing good conditions, nearing poor conditions, etc? Thanks
