Good job, Tim and crew!
I agree with you, the "home antenna operation with emergency power"
is a realistic scenario-- maybe more realistic than hauling a tent
out to the boondocks. Thus your simulation is perhaps even better
than the one where everybody heads for the hills. At least in the
LAX area scenario, when the BigOne hits, we know that going anywhere
in a vehicle will likely prove impossible to do. Shakeout, and other
sims, have shown us that even firetrucks are going nowhere,
immediately following the event. And, I think it's likely most
amateur radio towers will remain intact, so why not plan to use (or
repair) what we already have?
