I appreciate your offer of instructions re the ferrite bar antenna but I

think
I'll just skip it for now. This was the wrong group for this kind of

request.
It should have been in an electronics group.

The number of turns necessary for a loopstick antenna depends on several
factors.

1) the frequency range required
2) the permeability of the ferrite core
3) the spacing of the turns

For experimentation purposes, you might start with about 80 turns of AWG 30
enameled or cloth covered wire, contiguously spaced, near one end of the
core. With this, use a ~360 pF variable capacitor.

If you have a grid dip meter, you can easily find where this is resonant. If
you don't, then you have to poke about on the AM dial of a cheap radio, and
see where you can tune it.
