Default Simple AM Loop Antenna?

Thank You all for your input. I have decided to Build a tuning AM Loop. It
doesn't seem like it should too big of a project. It would be nice to
have the capability of tuning and I may mess with trying to make it tune
some of the lower Shortwave bands as well. Thanks again for all the input.
Great bunch of people in here

Easier said than done. If you use a 240uh inductor and you tweaked it for
minimum
interwinding capacitance your high end frequency (might) reach 1700khz. A
switching
system could be used that switched out some of the turns on your inductor,
this could
get you higher frequencies.
If you started with a 100uh inductor and a 365pf cap this would tune about
850khz
to almost 3Mhz.
BTW do you have the formula to calculate the resonate frequency?
Have tried any dimensions and turns and calculated inductors?
