REPLY:
In an emergency, you don't need to worry about intelligibility. Even the
worst disaster rarely exceeds a hundred mile radius. You are not
communicating with the other side of the earth. A hundred watts on either
75, 60 or 40 meters will do the job nicely and although I can't prove it
(and neither can you) I have no doubt voice will get through firstest with
the mostest.
Next time you talk to a cop, firefighter or EMT, ask them why they don't
give up their mike and go to PSK31 for their emergency comms.
I'd love to be there. :-)
BTW, 20 meters is a lousy band for emergencies. You don't need DX, you need
strong, reliable local communications out to a few hundred miles or so, day
or night.
75. 60, 40.
