+ AA6YQ comments below

AA6YQ's suggestion was:
Keep the rules as-is
AND
Offer a "single location endorsement" that says that you worked all DX from one small circle. This would be similar to WAS where all contacts have to be made from a circle of a maximum of 50 miles in diameter.

This is just an endorsement and does not affect the existing or any future DXCC awards. It is completely optional.

+ That's not correct.

+ My original proposal left the diameter of the circle TBD. When later pressed, I suggested a diameter of 1000 miles, comparable to the size of a "call area", but more careful analysis should be performed before finalizing this number.

+ It's important that a ham with antenna restrictions be able to construct or rent time from a remote station near his or her QTH without sacrificing their ability to earn the "Single Area Endorsement"; a 50 mile diameter would preclude that for too many hams.
