Scott,
Easy - 40m or 80m NVIS and a digital mode probably what we should be practicing with, anyway.

For a disaster, we should use the KISS principle. High Tech toys have no place in a disaster. A radio without a processor is best. The radio MUST be reliable and simple to use. It is no good if the inexperienced operator gets into the 500th layer in the menu and sets something wrong.

NVIS actually works really well here in SoCal with all the weird terrain. It's part of local emergency communications plans and all.
This experiment under discussion supports the development of communications resources that address a threat model of widespread natural disasters or widespread communications emergencies. It's obviously frail in the face of a global satellite outage. No communications system is completely robust.
For example, when the power goes down here, almost every amateur repeater simply shuts off. There are very few that have functional backup power. Simplex isn't really effective with canyons and mountains, so there's simplex mapping exercises and efforts to keep backup power systems working. These efforts have not been 100% effective.
It's a process to be prepared.
