I attempted to respond in the same "tongue
in cheek" vein--I never thought you were serious! I used some internet "extreme
smiley" characters, to attempt to convey that thought--I guess it didn't convey
very well. :))))))
I don't expect the FSL is going
to change the world but it's been fun playing with it, and I'm still doing
experiments and having fun.

my gosh, sorry Steve, I was being a little “tongue-in-cheek”, and my sincere
apologies to you at that. The cost of 40 Amidon 61 ferrite rods would be
several hundred dollars, almost as much as a Pixel RP Pro antenna w/o the
certainty of definitive results. I so very much appreciate the experimentation
that you and several other knowledgeable and intrepid explorers are carrying
out on behalf of the rest of us. I am hopeful that an optimized ferrite sleeve
system will result from the various experiments now being conducted, such that
the purchase of sufficient Amidon 61 rods might then be justified as part of a
debugged and optimized finished product. I anticipate that a ferrite sleeve
antenna with top of the line ferrite bar and litz wire components, with really
good protective coverings given the fragility of the ferrite arrays, will
easily run at least $100-150, which is a lot more than some throw down PVC
from Lowe’s, some Dave Schmarder litz wire, and a piece of ferrite from
deep apologies if my one liner email below was misinterpreted as either an
offer or a teaser!
