Question, can a CB transmit 700 miles?

At the power levels you are suggesting, globally during certain
periods of the sun spot cycle. *But that is not terribly different
with legal CB power.

So, if I'm hearing him on a daily bases speaking to someone that is
700 miles away, then it has to be a Ham?

At this point in the sunspot cycle, I would think that to be the case,
though summertime sporadic E propagation can put a CB signal down at that
distance.

As to his remarking that he wasn't doing anything illegal (CB with
amplification that some smarmy posters here think is perfectly OK); if
that be the case, then you need to fix your problem, because the FCC
does not mandate that a Ham legally using his equipment is obligated
to defer to your TV watching habits.

He's obviously not legal. He has been getting louder and louder over
the years to the point of what I described in my earlier post about
the problem with the TV's now.

How many times have you changed your equipment over the years? I mean
your audio equipment is responding to RADIO signals. Those are not
audio signals and the problem really lies in the fact that your equipment
is responding to radio signals that it SHOULD reject. As the years have
gone by, audio and TV equipment has used smaller and smaller devices.
Vacuum tube TV sets were virtually immune to this kind of interference
(though not to harmonic interference). Vacuum tube stereos were almost
never affected. Transistors began to dhange that. This is because
transistors are essentally the same kind of thing early crystal set
radios were made from. With the advent of microchips, the problem got
excessive, because some of the transistors are much tinier than the
crystal-catwhisker junctions of the old crystal sets. So put a strong
radio station, especially an AM or SSB station (if you're able to copy
your neighbour, that might be a clue that he's using CB, as few hams use
AM these days, but if he sounds like Donald Duck and you have to strain
to make him out, he's more likely a ham) near a modern stereo made by
companies more than willing to save 10 cents per product by leaving out
any credible attempt to suppress radio frequency pickup, and you have the
makings of a nasty problem. My Kenwood stereo is remarkably immune, but
Kenwood also makes and sells amateur radio equipment and has a reputation
to uphold with the users of same. Even so, I needed suppression on the
line cord, the stereo input cabling (except the digital inputs) and all
the speaker leads.

And even the very first time I approached him, I mentioned that I knew
he was broadcasting illegally, and that we all have our hobbies, but
his was interfering with mine, which at the time was home theater. He
didn't deny that he wasn't illegal, at the time, and he did lower the
power, for a while.

If he is running on the CB band. a local ham should be able to at least
veryify this. Power on CB is limited to 5 watts AM carrier or 12 watts
peak SSB power. Hams, on the other hand, are permitted a kilowatt.

I've approached this guy at least 5 times in the past few yrs, and
every time he has lowered the power, for a while. Not this time,
though, and it is now out of control.

Knowing the dimensions of the antenna might help, along with a better
picture.

snipped helpful info

One more thing, if he's a ham, he will sign his callsign fairly often,
whereas CBer's don't really have them anymore.
