Hi Everett,

You do beautiful work with your FSLs, and I admire your careful approach to designing these antennas, as you've documented in your articles.

Did this new FSL use a 64:1 ratio transformer after the pick-up coil? I think that was the ratio you've mentioned in the past which worked the best without loading down the receiver.

Also, could you comment on any gain or sensitivity differences with weak signals you've noticed between inductive coupling and direct coupling?
