Thank you for all your excellent and useful responses!

To clarify my purpose:

1- I've been waiting for an excuse to get into Ham radio. I'm very
interested in learning RF circuitry (Experimental Methods in RF Design
is enroute as we speak), and this is a perfect opportunity, because I
actually need it! So Im up for getting a license.

2- The purpose of the radio is for emergency and for the cool factor
of being able to talk to home from 100+ miles away in the desert and
tell them about all the sand and rocks i see. Exciting for them!

3- The CB does sound better for emergency. So now, lets change the
purpose of the ham radio to just "cool of taking to home 100+ miles
away". And I will get a CB for emergency.

I had been leaning toward 20 meters since it has been described
everywhere as the DX band of choice. Now I see that it may not work
well so "close" as 100 miles. But wouldnt 80 meters have even more of
a problem? I am still not clear on which band to use...maybe some more
help please?

Ok, so that needs a general class or better license at both end. Do you
have a family member interested too?

Look up NVIS, I described it in a post that crossed yours.

I guess a cellphone is out of range? You're not going to have reliable
"100+ mile coverage" with a CB or even with ham radio on a simple "push
button to talk" basis unless both parties are licenced and have some
knowledge about how radio works.
You need one of those 'illegal' phones like they sell in Brasil

Sat phones do this type of thing, not inexpensive though. Some of those
Brasilian phones illegally utilise military frequencies via US-DOD
satellites!

May I recommend a digital camera, 99 cent spiral bound notebook and a
pencil as the latest and least inexpensive technological breakthrough?

Go for it, then! You'll find that building stuff is definitely something
that's only worth it if you have fun -- the days of building stuff on the
cheap from dead TVs are long gone.

Hey! What about the rest of the world! You can talk to them, too.

Nearly all modern HF rigs cover 160 to 10 meters, so what you operate on
out there is pretty much limited by your antenna. What band is good is
mostly determined by the state of the ionosphere, which changes with the
day, time of day, day of the year, and the state of the sun. So I'd
recommend that you get or make an antenna that's good on a lot of bands,
and find what works best for you.

The only real caveat to that is that longer wavelengths and small
antennas don't go well together, so the system tends to be much lossier
for 40m and longer with your average car-mount antenna. That doesn't
mean it can't work, it just means that you have to take more care with
the antenna, or plan on packing a BIG antenna that you can put up when
you stop.

Get a modern solid state radio that covers all HF ham bands and an
antenna such as the "Outbacker" or "Screwdriver" so that you have one
mobile antenna capable of being tuned to any HF band. I would say that
40 meters would be one of the better choices during the day but with the
multiband antenna, you try the different bands until you find the one
that works at the time you try calling.

Yea verily. What I was trying to say, only better stated.

40 meters might be better. 20m if conditions permit. 80m at night but is
more difficult for mobile ops. Your choice of frequencies depends on time
of day, seasonal and subject to the ever changing ionosphere. Typically
what frequency works at a given time of day will work the same time the next
day but maybe not. Some study and experience is required.

Just to give some idea of the variability of 'Amateur Bands' due to
solar radiation, time of day etc.
Back some 50+ years ago had a war surplus receiver and on 20 metres
(14 megahertz) band could listen to the Australian amateurs rolling in
and chatting with the UK and Stateside hams early morning while f
getting ready for work. And this was with AM (Amplitude modulation)
and often with self built rigs. A few years later 20 m was dead.
(Sunspot cycle!).
Also operating at 5 megahertz military reserve frequency we sometimes
could transmit/receive hundreds of miles but not 40 miles to another
unit. It's radio!
Have fun.
