Don't forget solar power. Lots of hams add solar cells to their field day equipment.
I have solar powered and battery powered...From CA, I can talk to ships off the coast in Alaska, Europe, or people living in the Australian desert, tiny south pacific islands, or to someone in downtown Philadelphia.
All without AC power.
Believe it or not, HF frequencies are teaming with amateur radio people communicating in code as well as voice with homemade antennas, and solar power/batteries etc.
Even without a collapse, it's a lot of fun.
