They might get upset but it would be something really weird, if it ever
happened, considering a standard CB transmits on less than 5 watts, a B-52
would have to be flying mid service ceiling and directly overhead to cause
much interference.

Up until the time that MCAS El Toro was closed, there were plenty of
times that B-52s would come in to land over one of the busiest freeway
interchanges in the world (the junction of the 405 and 5, called the El
Toro 'Y'). They weren't very high above oodles of truckers at that point...

The problem is that people are modifying ham radio gear to transmit at
MUCH higher power levels in the CB band. They get much longer range but
tend to splatter signal outside the CB band...
I think that is why the original poster told eBay that the equipment was
unmodified. That was obviously too fine a distinction for the eBay
screeners.
I would expect eBay to have "specialists" to screen particular bid
types. That doesn't seem to be the case... 8(

I suspect those who can modify CB's to operate on illegal frequences have
the know-how to jack up the power too ... they're operating on a lot more
than 5 watts.

I spent many years working on the B-52 Weapon Systems Trainer (simulator).
During that time I was well aquainted with some of the top Buff crews and
the aircraft capabilities. A friend who was a top radar navagator in the
B-52s and was the test director for the acceptance of the Block 2 upgrade to
the simulator used to tell me stories about CB and RC transmissions and
their effect on the B-52. You don't have much to worry about except the
loss of your equipment if you bother these people.
The vehicle has equipment that can scan all frequences and jam anything they
want. He enjoyed flying over R/C sites and when he saw more R/C activity
than he cared for he had several choiced depending on his mood. He could
chose to ignore them. He could put enough RF out on their frequences to jam
the transmitter to receiver connection, resulting of the loss of any plane
in the air and if he was feeling really vindictive, he could send signals
with enough power to literally burn out the flight packs in the airplanes.
So I don't think we have much to worry about in terms of causing RF problems
on a B-52. But it would behoove you to be aware of your surroundings and
try to keep emissions to a minimum when these aircraft are making training
sessions in your area. It's a loud aircraft, when you hear one, clear the
airspace so they can do their job and keep us all safe.

"More that he cared for"...just what does that mean? Since when are
military personal authorized with "Judge Dredd" style enforcement of
civilian activities? I wasn't authorized to run over civilian vehicles
in the 5 ton recovery unit I operated if they broke the law, no matter
how tempted I might have been.
Sounds like a court martial looking for a location. Or BS.

Really starting to smell now, and it ain't the smell of burned
transistors, either. Not the technical feasibility, but the idea that
someone actually did these actions.
