Without a lot of compression and clipping the duty cycle for SSB is only
20%. Given 100W out at 60% efficiency, we are looking at roughly 167W
input at the 20% duty cycle or roughly 34 watts. Depending on the
exciter we are looking at less than 100 watts total power consumption
for a 100W SSB signal output. Often, much less power consumption.
Unfortunately this is not true for the new, top end rigs with all the
bells an whistles.

Humor aside, one thing that phone transmitters require is power. The fact
that you can copy a CW signal at a far lower signal level than a phone
signal means that lower power can be effective.

A car battery will power a 100 watt SSB rig for a long time.
If you're serious about emergency communications, be prepared.
