is an STA needed to transmit data on CB channel 40?
 

Its just not good business. Peace works against Fear, Uncertainty and
Doubt, the prime movers of the business world. Why would you suggest
such an irrational thing?

Thank you all for your suggestions.

This is not a hoax. But I too find the need sufficiently implausible
that I feel a little bit queasy taking R&D fees for a cause like this
at $50 per hour. The only reason that I'm not mentioning the
consulting firm is that I could stand to get paid... and any money is
better than no money. And if I'm the king's coin then I ought to make
it work.

I agree, Truck stops are a very good idea for commandeering CB's, but
you only find those in the exurbs.. Yes, other commercial radio
services could and maybe even should be drafted into this. The squad
lead could then determine the tradeoffs based on the availability of
foraged equipment.

Allison, your idea of using the dummy loads to simulate fading over
distance is OUTSTANDING. I'll do it!

Using dummy loads as a demo, I could then get the consulting firm to
ask the FCC for an STA for field tests.

For my test rigs, I'm intending to plug in a laptop sound card I/O into
the SSB mic and headphone jacks. Therefore no type acceptance needed
because no mods.


As soon as you plug in something other than the approved mike, you have
probably broken type acceptance.


My brother says ideally in the scenario, each squad leader should only
need to carry a mini-CDROM in his or her pocket. The squad lead could
then commandeer a laptop, an SSB CB radio, and then use an abandoned
automobile as an electric generator for the laptop and radio. Antenna
would be flung over a 3 story office building.


SSB CB radios are fairly rare nowdays.

The microphone connection is non-standard, and won't directly wire to
a sound card.


A wire flung over a 3 story office building won't be matched. It will
likely work poorly, or it may even fry the transmitter.


One of the reasons for this scenario is to lighten the overall squad
load and thereby increase the speed of response. That way each squad
could break into an abandoned store and then set up a first responder
posts.

A 1 to 2 pound VHF radio will give better coverage, will function as
they are going in, and will free up personnel labor for more important
tasks.

Wasting a person's time setting something like this up is more serious
than carrying a small hand-held radio.

No, it isn't. Many use higher voltages.


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.

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.


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.


Carrying a 1 to 2 pound VHF radio in will provide communications all the
way in. Using it will save a lot of personnel time that can be used for
something more important that hacking together something with a CB that
would work very poorly if at all.


Conclusion: This must be a troll. I hope that nobody in our government
is *STUPID* enough to fall for such a plan.
