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.

@[email protected] 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.

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.

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.)

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.

@[email protected] nice short call signs in CW!

@[email protected] It makes sense they'd use something more omnidirectional / lower gain, and broad spectrum for backups.

@[email protected] 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.
