During the 20th century, AT&T operated a shortwave "radiotelephone" service for vessels on the high seas. Ships could contact an operator, who could connect them with any landline telephone number they wished.
The North Atlantic station, callsign WOO, occupied expansive transmit and receive "antenna farms" in marshlands near the shore in central New Jersey.
Rendered obsolete by satellites, the service ceased operation on November 9, 1999.
There were three AT&T radiotelephone sites in the continental US, each with its own transmit and receive antenna farms: Ocean Gate, NJ (shown here, serving the North Atlantic), Miami (serving the Caribbean and the Gulf), and Point Reyes, CA (serving the Pacific).
All the sites have by now been razed, either for redevelopment or as nature preserves. The antennas are mostly gone now.
Ships on the high seas still occasionally make some use of shortwave radio, but its importance has greatly diminished over the last few decades. The Coast Guard still maintains a "watch" on emergency shortwave frequencies, listening for distress calls, but most transoceanic ships are now equipped with more modern, higher-bandwidth satellite communications systems.
These places are what the Internet looked like a century ago.
I should note that while the site had a number of discone antennas like this one, they were mostly there as backups in case the main antennas (including truly massive wire rhombics pointing toward various oceanic regions) or transmitter combiners failed. The old Bell System did not mess around.
@mattblaze@federate.social It makes sense they'd use something more omnidirectional / lower gain, and broad spectrum for backups.
@mattblaze@federate.social Often felt that if AT&T leadership had been visionary, instead of focused on charging you $1.50/month for a long handset cord, there'd be no Internet or cable teevee.
Here, by the way, is what I believe was the last published frequency list and schedule for the High Seas service. (A souvenir of my last visit to the station before it went off the air.)

My Dad was in the Coast Guard before and after the Korean War, and a couple of his tours were "weather patrol" between Newfoundland and Bermuda. In addition to taking observations using wx balloons and radiosondes (I believe), he talked about regularly patching airplanes into the marine operator system. I was surprised to hear him talk about that — i.e., seems like aviation did not have the same communications infrastructure, so the piggyback was necessary.
@mattblaze@federate.social What gorgeous typesetting.
@steveyaeger@mastodon.social especially the waves made of dingbats under each station name.
@mattblaze@federate.social @steveyaeger@mastodon.social Here’s info on the receiving station at Pt Reyes, from the NPS: https://www.nps.gov/places/point-reyes-kph.htm
@mattblaze @steveyaeger I recall seeing those antennas as recently as ten years ago, but they had clearly fallen into disrepair even then.
@jgkoomey @steveyaeger There were actually three HF receiver sites at Point Reyes. There was the AT&T radiotelephone station KMI (which was completely razed about 10 years ago), which was next door to the still-alive-and-kicking RCA radiotelegraph station KPH (worth a visit when open). And up the road a bit is the still-active (but remotely controlled) Coast Guard station NMC.
KMI had this spiffy sign, which I'm told was saved and is in storage somewhere.
@steveyaeger@mastodon.social @mattblaze@federate.social @jgkoomey@mastodon.energy there are some really cool videos on the MRHS website about KHS, but probably the most interesting is DA sending the last sign off. https://www.radiomarine.org/mrhs-videos

Point Reyes, hmm that rings a bell in me. I am sure I intercepted this station as well. Need to look it up my qsl archive.
@jgkoomey @steveyaeger
Did not find it immediately but I found another US Coast Guard station, Portsmouth. Plus RCA Chatham maritime station. Notice the nice personal handtyped QSL with number of technical detail on Trx and antennas.
Happen to know these @mattblaze ?
@harkank @jgkoomey @steveyaeger the RCA Chatham station (WCC) is now a nice museum. Worth a visit if you’re in those parts!
@mattblaze@federate.social @jgkoomey@mastodon.energy @steveyaeger@mastodon.social
You know you are getting old, when your past intercepts have turned into today' s museums. 😎
Solar cycle 21 from 1976 onwards was a fantastic HF season especially on the higher bands.
Pse keep posting these photos of HD stations, Matt & I'll try to come up with appropriate QSLs. 😎 Only parts of the collection have been digitalized so far. Should be a few hundred.
@jgkoomey @steveyaeger
What I appreciate about this is that the logo dates the sign to the 90's, when high seas HF radiotelephone was already no longer exactly a growth business for AT&T, but someone still loved the place enough to make a beautiful carved wooden sign for it.
@mattblaze@federate.social @jgkoomey@mastodon.energy @steveyaeger@mastodon.social I should ask around. I know a lot of those sign makers on the California coast. I should see if I can figure out who made it.
@mattblaze@federate.social
The Marine Radio Historical Society has restored the CW (Morse code) stations at Point Reyes and operates KPH KSM and KFS (as well as ham station K6KPH, mostly on Saturdays.

@k8quinn@vivaldi.net yes, great folks!
@k8quinn @mattblaze I've been wanting to visit KPH. It looks like a really interesting place!
If I was a mariner today, I would want to make sure I've got a couple of short wave radios in case satellites become unavailable...
@douglasvb @k8quinn It’s absolutely worth a visit, and they’re really nice people.
@mattblaze@federate.social @k8quinn@vivaldi.net I think we might go that way in January for a long weekend so we'll be sure to stop by.
I've passed the building many times in the last 30 years but until a year or so ago I didn't realize what it was!
@mattblaze@federate.social nice short call signs in CW!
@mattblaze@federate.social WOO!
@mattblaze@federate.social Wow! That’s really interesting, thanks! I wonder if we are going to regret being dependent on satellites for all comms in the next decade or so - the risk/threat profile seems to have changed since 1999.
@mattblaze@federate.social
just a fwiw
there are some wild antenna farms way out in West Virginia
long wave stuff
