I am the Township Historian in Lawrenceville, New Jersey (near Trenton
and Princeton).
I am in the midst of compiling a history of the former AT&T shortwave
transmission facility that operated in our town beginning in 1929. For
three decades it was the primary outbound telephone link from the USA
to Europe and Latin America. At its peak it could generate one million
watts on the 16, 22, and 32 meter bands. The 800-acre site is now a
county park.
Here are three questions I would like to throw out to the community:
(1) Does anyone have any personal memories, photographs, or documents
regarding this station, or know of someone who might?
(2) Can anyone suggest why this particular site was chosen? Proximity
to New York was one factor, but AT&T documents say "extensive tests"
were conducted before settling on the site. I have had no luck in
finding any. I assume this has something to do with ground
conductivity but I am no expert on this.
(3) The initial antenna system in 1929 was of the "curtain" variety
and it is well documented. Subsequently that system was replaced by a
rhombic system, probably in the 1940s. There is very little
documentation on this system and I would like to find some. The
rhombic system remained in place until the station was decommissioned
in 1963.
Thanks in advance for any help. Please feel free to forward this query
to other lists or individuals. And apologies if you received more than
one query due to cross-posting.

Bell Labs wrote a multi-volume history of the company which includes
extensive chapters on radio-telephone work. They may be in Vols
1 or 2. They may give insights into why Lawrenceville was chosen.
Rider University Library should have copies of them. Extensive
studies were done at that time into radio wave propagation and
reception and probably was a factor in site selection.
There are two telephone history groups that may be able to help you:
Telephone Collectors International and Antique Telephone Collectors
Association.

Dennis,
The book "A History of Science and Technology in the Bell System,
Volume 1, The Early Years" has several pages of detail surrounding the
Lawrenceville station (starting on page 410). Apparently the site was
chosen to minimize interference from other stations and was used for
US - London ( circuits) and US- Buenos Aires (one circuit). The
transmitter was at Lawrenceville and the receiver was at Netcong, NJ.
The book contains block diagrams of the antenna and the transmitter.
Unfortunately, the book is out of print. Check with your local
libraries or Bell Labs Murray Hill (if it still exists....) to see if
they have a copy.

I moved to Princeton in 1964, and I distinctly remember the poles and
wires being up for a long time after that, perhaps into the 1970s.
There was (and is) an orchard across the street where we bought apple
cider so we'd be out that way at least several times a year.
R's,
John

Well, the first web link correctly identified my wireless carrier for
a ported number that used to be a Verizon land line at my house. The
number was ported several years ago, so whatever databse they are
using has had time to catch up.

That's funny, I was about to ask exactly the opposite question. Now
that we have the Web on which to look up whatever we want to buy, and
it has plenty of good comparison sites, all ads in other media (except
maybe those media that exist only for the purpose of ads, like the
Penny Saver) have lost their usefulness to the consuming public. In
effect they are nothing but nagging. Why does the TV watching public
continue to put up with them, at all, ever? Do we need the
commercials to tell us it's time to go to the bathroom?
Fortunately, Tivo and its competitors are rapidly making TV ads so
easy to skip that they're becoming as useless to businesses as they
are to consumers. Now Hollywood is just left with the problem of
making TV shows good enough that people will pay for them.
I predict the demise of free (unencrypted) over-the-air TV any day.

Except, of course, that the latest research shows quite the opposite:
most people can't be bothered to skip the commercials. See, for
example, <http://www.onthemedia.org/transcripts/2009/11/06/03>.
