Then we're back to traffic analysis. If they stay up, they get
killed. If they don't stay up, coming up tells you something is going
on. No way around that.

Actually there's something I forgot to mention - using similar spread
spectrum techniques as, for instance, GPS, it will in general be
fairly hard to tell that a high tech wide bandwidth low power
transmitter is "up" at all.

So even the 24 hour radiating link might not be terribly conspicuous
from an emissions point of view. And the backup links will be even
less conspicuous.

OTOH I would guess that good (high altitude with good field of view)
locations for antenna systems will be bombed as a matter of principle,
including anything that even looks like an antenna farm.

In any event, one of the first profitable investments for Elbonia
might be a modern C&C infrastructure that will be hard to monitor,
spoof, or take down.
