Would like to build a one tuber for the 20 meter band. Most of my regen. builds have been for 40 meters,not a lot on there now but Cuba and a lot of preachers. Does anyone have a suggestion for the coil capacitor combo for such a build?

FYI
20 meters has been pretty lousy this summer. I don't have much of an antenna, but do have a nice ICOM rig.
