Funny, the last laptop I bought doesn't include a 12V cable. As a
matter of fact, neither did the one before it. You had to ask for
it as an add-on.

a bunch of CB radios with documentation on the mic input,

The docs could be on the CD-ROM. Squad leader or designate
could read that using the laptop.

And just where do you get this CD-ROM in a deserted, destroyed building
after the catastrophe?

Oh yeah, you've got the schematics of every CB radio ever made on
CD-ROM already and you are taking it with you.

Right,

a soldering iron to make up a mic/laptop interface cable (assuming
you can use the existing mic cable connector).
Shouldn't be too hard.

Of course every squad made up of random troops from the motor pool and
the rifle squad has a portable soldering iron, knows how to solder
and has solder.

Or or all these troops going to come from the Signal School?

Oh, wait, they are going to commandeer the soldering irons and solder
from the destroyed businesses and plug the irons into the none-functioning
AC grid, and learn how to solder from a CD-ROM.

How could I have been so stupid with only 30 years in the Army?

Maybe from teaching soldering classes?


The only problem left is how to get the abandoned automobile to the
top of the 3 story office building (if any are left standing in this
disaster).
The feed could start at street level and connect to a dipole on the
rooftop.

So where do you get the custom power cable or antenna cable to go
up three stories?

Three stories worth of cable is going to weigh a lot more than most
radios these days.

Might as well bring the radios with built in antennas and battry packs.

Clearly you are only skimming my posts rather than reading them.

Starting at the beginning:

1) Squad leader carries a mini-CDROM in his/her pocket. That's the
nucleus
for everything else. With luck, nothing else need be carried into
the field.

2) The CDROM would contain schematics and part numbers of everything
necessary
to forage to create a datalink.

3) SSB CB Radios (funny, my RS always carries the SSB CB radio as the
high end
model) would be one of several pieces of RF equipment
that could be foraged off the street (i.e. Radio Shack stores,
truck stops, etc).

4) Most new laptops carry 12V power input. Older ones don't. There
are plenty
of sources to forage a laptop from: Target, Walmart, and K-mart
come to mind
as well as Radio Shack.

5) The laptop, radio, and car are all at street level. People can
take plain old copper
wire and make a dipole or inverted Vee with it, hanging it from the
roof top. The only actual ground to antenna connnection comes
between the radio and the center of the dipole or inverted Vee.

Caught up now?

Actually, I was reading them and comparing them against my real world
experiences with combat boots in the dirt.

Starting at the beginning:

the field.A

A military force that goes into the field depending on luck is doomed
to failure.

It doesn't matter if it is a combat situation in foreign land or a
simple training exercise within sight of a major US city.

If you don't have everything you need going in, or at least a supply
chain that can get it to you quickly, someone is going to be hurt.

This comes from bitter experience.

2) The CDROM would contain schematics and part numbers of everything
necessary
to forage to create a datalink.

You are going to supply an up to date CDROM containing all the info for
all the CB radios in the US?

Yeah, that's going to happen

3) SSB CB Radios (funny, my RS always carries the SSB CB radio as the
high end
model) would be one of several pieces of RF equipment
that could be foraged off the street (i.e. Radio Shack stores,
truck stops, etc).

Assuming there were such stores in the first place and they aren't
flattened/flooded by whatever the catastrophe was.

4) Most new laptops carry 12V power input. Older ones don't. There
are plenty
of sources to forage a laptop from: Target, Walmart, and K-mart
come to mind
as well as Radio Shack.

Getting a laptop is a minor problem. Getting a 12V DC connector and
someone that knows how to wire to a field expediate power source
correctly is a major problem.

5) The laptop, radio, and car are all at street level. People can
take plain old copper
wire and make a dipole or inverted Vee with it, hanging it from the
roof top. The only actual ground to antenna connnection comes
between the radio and the center of the dipole or inverted Vee.

Where does the antenna feed cable come from? The collapsed/flooded
store?

Where do you get the person that knows how to wire up an antenna
and feed cable?

Where do you get the person that knows how to cut a dipole or
inverted-vee, or even what those terms mean?

Most troops are really good at what they are trained for. Few troops
have been trained in anything to do with electronics or even electricty.

Special Forces troops are probably the most veratile of troops (and
the smallest in number), but without the training they would be
useless.

You want them to parachute in during the dark of night, take and
hold a tactical position, no problem.

You want them to cut and connect a diplole, big problem

Upon what do I base these statements?

Years spent teaching such subjects to troops.

Caught up now?

I never was behind.

You, however, have no concept of what it is like to have boots in
the dirt.

Your prolly talking to one of those Pencil Pushing pentagon admin types we
had to deal with . They
have no concept what its like to be in the field.

You know, then again the idea doesn't want to know.
If they ( the first responders) find a working (unwet and
undamaged) CB radio, battery and antenna they could
just pick up the mic and TALK. That would would be
both cost effective and requires far less effort/training to
implement. It would also conform to the CB norm and other
gasp operators might be part of the assistance. There
may still be people working the REACT system.

For those that remember before CB became littered with
carriers and other flotsum and jetsum CB was considered
a very good tactical radio due to it's channelized character.
Since then portable amatuer HTs, FRS and GMRS radios
became available and reliable and share in that tactical
capability without the need for a 9ft whip.

E.S.-

You are not easily discouraged!

Consider that many who have posted negative comments here, have years of
experience in the military. Others have experience in providing
communications systems for field deployment. Their comments may not have
addressed all the points you posted in order to maintain brevity. I
detect a consensus that your brother's proposal is not practical, even
though it is theoretically possible.

Reading your postings, I can't help but recall two experiences from my youth:

1. A snipe hunt.

2. Trying to catch a bird by putting salt on its tail.

I guess it is the new laptops that use 12v, the only laptops I have here
have an 18v adaptor for the Zenith or 120v input for the Toshibas. I guess
noone will be borrowing mine to use in an emergency. What sort of emergency
responders are going to be sent in with no equipment?

With the right soundcard software a laptop could emulate a bell 202 or 103
modem over AM radio, even with packet error checking to reduce transmission
errors. What no one has mentioned yet is channel usage, one simplex data
channel for an entire disaster area with no provision for collision
detection between users other than just listening for someone else
transmitting? With the central data collection point high enough to cover
the entire area, you will be in the position that each transmitter may not
hear another but the reciever can hear both while transmitting at the same
time. The data collector would spend quite a bit of time acting as net
control determining which remote site was allowed to transmit at any
particular time. Just my $.02 on this poorly thought out idea.
thanks, John.
