the old loopstick type coils, looking for

Thanks David

Wonder if an adjustable coil loopstick and variable capacitor
preselector between the antenna and the crystal set would improve

Nope, you have the same problem with loaded vs. unloaded Q and efficiency.

You can get there from here, you just can't do it with that loopstick.
