Good Reading and Worth Printing Out for Future Reference.

Now it looks like it is back to the Drawing Boards.

Guess I will make out a Spread Sheet for a couple of different
Ferrite Cores and start winding.

This pdf is quite useful:

It takes you through how to do the calculations for any
torroid that you purchase.

Large torroids and Wire Wrap wire (solid core) are quite
effective and easy to handle.

I found that Type 43 material with even with windings for 2 mhz
and above is still quite effective for MW. Effective enough
that I get images on my Tecsun PL-550 between 2 mhz and 3 mhz
of distant MW broadcast stations that disappear when I unplug
the antenna.

I vote for MATERIAL K.
