Before INMARSAT began to provide satellite radio service to ships at sea, the only way to send a message to a ship was through a coastal radio station, either by voice or by telegraph. (I think that teletype service was available through Rogaland Radio in Norway, but not in North America.) INMARSAT is quite expensive ($12 per minute from Canada), but even so coastal radio stations are closing down in the U.S. {Popular Communications} Magazine reports that Western Union has filed with the FCC to shut down its coastal telegraph station KFS (location unspecified), and that some other coastal telegraph stations, WPA, WOE, WMH, WSL and KOK (locations and owners unspecified) have already been closed down. No doubt some traffic that formerly moved through these stations now uses cellular phones. I have seen references to coastal telegraph stations operated by RCA and TRT, but this was ten or twelve years ago. Does anyone know whether there were competitive coastal telegraph stations in a given market, or whether such stations had a local monopoly? Coastal radio stations in Canada are operated by the Canadian Coast Guard. Nigel Allen telephone (416) 535-8916 52 Manchester Ave. fax (416) 978-7552 Toronto, Ontario M6G 1V3 Canada

Well, I have to say "thank you" to Nigel for raising a question near and dear to my heart that caused an excursion back to a comfortable past career. I was prompted to answer the question in part from my personal library and experience, but also to get on the phone to have a very pleasant chat with my old Almer Mater of international shortwave radio, WOM at Ft. Lauderdale, FL. Here's an attempt at summarizing a lot of detail: While yes, it is true that shore telegraph stations are retiring from the airwaves, and significant shifts are occurring. Maritime Mobile Radio using Medium Frequency and High Frequency radio is, believe it or not, still growing, and MARISAT/INMARSAT are far from supplanting it. And this in spite of some incursions by cellular radio as well. First, we must make it clear. Until or unless there comes to pass a global form of radiotelephony like Motorola's IRIDIUM proposal, there are vast stretches of ocean reached only by HF radio or INMARSAT. My phone inquiry to WOM found them very aware of these developments, revealing they found that while some ships, mostly supertankers, bought into INMARSAT, the $10 (U.S.) per minute rate compares poorly with the $4.90 per minute of HF radiotelephone, especially because INMARSAT bills from the moment of connection while High Seas (HF) radio makes all calls person-to-person and bills only when the conversation starts. Apparently shipping companies come to this conclusion when they get their bills, and find that a call to the ship's steward for a one-minute talk results in a $100 charge while they wait on hold for him to be paged to the satellite phone! What the WOM folk knew was that satellite-equipped ships use INMARSAT for hard-copy communications, running not only Telex but even PC's at 64 kilobits off the ship. That's what's killing the shore telegraph stations. They're not all dead however, just shrinking back to meet reduced demand. For that structural background Nigel asked about, shore radiotelegraph stations in the U.S. grew before there could be any structure to their sub-industry, mostly as "company" stations. For example, the origin of TRT Telecommunications, today in Washington, DC, was as a 1912 ship and shore radiotelegraph operation of the United Fruit Company in Boston, using 1912's "highest tech" to direct shiploads of bananas to the best markets while enroute. That expanded to using radiotelegraph to the plantations in Central America, and that expanded to TRT becoming the international telegraph (and sometimes international telephone) company of much of Central America; the entity on the other end of AT&T's point-to-point HF radiotelephone from the U.S. RCA, of course, made shipboard radios for many American-flag ships (remember that David Sarnoff, builder of the RCA empire, was first a Marconi Corp. ship's radio telegrapher.); the result was RCA building a string of shore telegraph stations for its customers. And, the RCA shore stations operated radioteletype as a service to promote sales of shipboard RTTY gear. ITT got into the act by owning Mackay Marine, which competed with RCA for maritime radio equipment and services, and so had a string of stations, too. There was no territorial or service monopoly. In fact, just the opposite seems to have happened, and caused some significant words in the (U.S.) Communications Act of 1934, to the effect that (sic) radio stations for public correspondence must accept communications and traffic from any mobile station, because the "company" stations had, in fact, refused to answer calls from (even distressed) ships of other companies. What developed from that point was an interesting form of competition of many years' duration. The shore stations did compete with attempts at camraderie and service in ways only telegraphers could understand. Imagine if you can, an unseen, unheard person on shore exuding warmth and personality via a telegraph key ... and they did. Despite the shrinkage of the number of radiotelegraph shore stations, the remaining ones seem to be enjoying growth by picking up the slack. For example, WPD at Tampa, FL seems to still be going strong, independently owned as it has always been, handing its traffic off as domestic telegram and Telex messages (that have now largely become E-Mail with PCs). One of the other "company stations" that never operated maritime traffic, the Trans-Liberia Radiotelegraph Company (built by Firestone solely to communicate with its plantations in Liberia) seems also to still be in business from Akron, Ohio ... but has been off HF radio for many years, and is now largely a message center with a couple of PCs ... but you could, if you wanted to, send a telegram to Liberia via Trans-Liberia! As to the telephone business, INMARSAT, as noted, may have made some market, but it seems to be rather insignificant to WOM and it companions. Their market still grows. AT&T has operations at WOO near New York, WOM near Miami and KMI near San Francisco. The single most significant part of the traffic is cruise ships, that enjoy handsome profit margins on phone calls to shore for passengers. It's known that one cruise line tells passengers they are on satellite, and charges $30 per minute, while putting the calls on HF radio (yes, HF can sound mighty good, running SSB radio with Lincompex) where the shore station charges $4.90 less a $1 "commission" to the ship! The surge of technology has helped, with $800 SSB transceivers, so that small ships and private yachts get on HF radiotelephone, too ... not wanting to pay the price of a satellite shipboard station and then the per-minute rates. They have fueled the surge in minutes, along with ... of all things ... aircraft! The WOM folks handle a fair amount of calls for private aircraft, notably some Venezuelan oil company planes that travel from South America across the Atlantic and Africa to Saudi Arabia. Some few "hep" international airline captains have even found their HF transceiver can get them a phone call to home while crossing the Pacific at 35,000 feet! The result is that WOM alone of the three AT&T stations is handling about 700 revenue-producing calls a day. And, the traffic of the one privately-owned U.S. station for international telephone traffic, WLO at Mobile, Alabama seems to also be healthy. The standards bodies seem to sense this growth, for in 1991, the channel assignments for HF maritime radiotelephone use will be restructured again, with narrower channel widths (2.8 kHz) to create more channels. As mentioned earlier, the sub-industry is restructuring, in some cases with technology old-timers could never comprehend. A major change has been and continues toward automating and reducing overheads by consolidation. As I write this, work is underway to consolidate the control point for NY's WOO in the WOM control room at Fort Lauderdale. Similarly, the local telcos who always ran the medium-frequency (2 mHz) Coastal Harbor operations abandoned them with demonopolization, and WOM took over Miami, Jacksonville and Charleston, SC, running the whole works with the WOM callsign and 10KW transmitters, while the receivers along the shoreline are wired to Fort Lauderdale. The communications technology behind it is in some ways awesome, in others what we should simply expect. The WOM location in Ft. Lauderdale is 50 miles from its transmitters in Pennsuco, west of Miami, while the actual landline telephone operators all the ships speak to are in Pittsburgh, Pennsylvania! Not such a feat when you find out that the building is also AT&T's fiber POP for Ft. Lauderdale and WOM enjoys its own whole fiber route direct to Pittsburgh! Meantime, control of the transmitters is by PC messages shot around AT&T's packet data net to turn a transmitter on or off or change its antenna ... no clunky old "control circuits" at all; instead messages from a 3B1 UNIX machine (yes, they are planning to get 3B2s) that go on a packet network to be read by similar machines with control interfaces at Pennsuco (and soon, Manahawkin, NJ for WOO ... with KMI's Dixon, CA transmitters a likely addition someday). And, HF radiotelephone even has its disaster function. During Hurricane Hugo's trip through the Virgin Islands and Puerto Rico last year, the first restoration of telephone connections to the U.S. was from ship radiotelephones there to WOM for several days. Of course, the world gets little news from the networks about such undergirdings of telecommunications. If people had wanted, they could have as well made phone calls into the U.S. telephone network (and thus the world) via WOM in the Mexico City earthquakes. FCC rules do permit doing ANYTHING with a radio transmitter if it is for the safety of life and property ... but that doesn't mean calling to see if Uncle Fred's attic window got broken, it means serious PUBLIC safety. Oh, the cellular incursion. Yes, it's there, but again not that significant to a growing market. First, cellular of course, reaches only incidentally a few miles offshore. There are automated VHF marine-band dialable shore stations that do reach seaward, but perhaps only 50 miles offshore. Run by a private company in Hollywood, FL, these similarly are remote controlled from that city, even though they range along the whole coast. And, in the Bahamas Islands group there are reported to be two cellular companies among the islands, Cruise-Phone and Boat-Phone. They serve an obvious purpose for boaters sailing among the thousands of Bahamas Islands, but only there. Growth seems apparent in other areas, too. St.Thomas in the Virgin Islands has HF voice station WAH that is growing, as do several of the other nations' Caribbean islands ... French, Dutch, English and so on. And, of course, around the world, there are the established stations of many nations. The "territorial monopoly" is rather interesting when the Laws of Physics interfere. It's very difficult for nations to legislate what shore station a vessel calls ... even though some do force it economically, witness the Cuban shore stations with their own and Russian ships, plying the same waters, but never getting on the channels of the American stations, even though they easily can. So, I hope this is the kind of response Nigel wanted. It's a peek into another galaxy of telecomm that most people don't even know exists or thinks is dead is the kind of response you wanted. From the figures I got today, it's another telecom business that grosses at least $15 million a year, and perhaps several times that. And, since this peek got so long, here's a vignette learned yesterday from the WOM Technical Operator I chatted with. We were comparing stories about handling REAL emergency traffic, as anyone who has done that job has done, as he gave me a real side-splitter. Seems he worked the third shift for a couple of years, and in the darkest hours of night, traffic tends to be nearly zero. However, one night at 3 AM, he heard a whispering voice on the speaker of his calling receiver saying, "Hello? Is anybody on here?" He lit up a transmitter and answered, whereupon the caller identifed himself as a ship and said, "We are under attack by the Indians!" What? A ship at sea under Indian attack? What it turned out to be was s small freighter that had run aground on remote shoreline of Nicaragua, and the natives were boarding the ship and stealing everything in sight! Not daunted by this at all, the WOM T.O. called the U.S. Coast Guard District Office to find out what support was available, and within a short time the Nicaraguan National Guard was dispatched to quell the Indian uprising. If you think, "Having that job must be a ball," you're absolutely right. Many is the time I've thought I should have stayed there. Pity it's only one that employs a handful of people. Oh, it's not a "secret" place although not in tour books. Located at the corner of State Road 7 and Sunrise Boulevard in Fort Lauderdale, just look up AT&T Company and give 'em a ring if you want to visit! [Moderator's Note: *Thank you* for a very interesting and informative article. I'm sure you are correct that this is a form of telecommunications very few people know anything about. I hope your article has educated a few of our readers today. PAT] ------------------------------ End of TELECOM Digest Special: Coastal Telegraph Stations ******************************

> St.Thomas in the Virgin Islands has HF voice station WAH that is > growing, as do several of the other nations' Caribbean islands If you've ever cruised the Virgin Islands, you know that WAH (more popularly known as VI Radio) is more than just a way to phone home. The nearest National Weather Service transmitter is on Puerto Rico, and doesn't quite reach St. Thomas, let alone the other islands. So, on a regular schedule, VI Radio (who, with the tallest mast on St Thomas, apparantly can hear NWS Puerto Rico) rebroadcasts the NWS weather reports. They can be heard all over the USVI and the BVI on VHF 16, and even further on HF. Everybody tunes in at 1000 to hear the list of waiting traffic and get the weather. They also don't seem to mind being the universal ping object, answering requests for radio checks from anybody within range. There seem to be more VHF radios in the Virgins than telephones. Every business that has anything to do with boats (i.e. most of them) stand by on 16 (or some other channel which they advertise next to their phone number) waiting to take dinner reservations, schedule diving trips, or anything you might normally pick up a phone to do. We once had to call our charter company to arrange for some spare parts. We couldn't get them on VHF (probably their little antenna was below our horizon) so we called VI Radio and had them place a phone call. When they still didn't answer, we kept VI Radio on the line for what seemed like for ever, trying different numbers (in conditions under which we could barely hear each other) until they finally got through to somebody. Never once did they suggest that the amount of their time we were taking up (for a non-emergency), compared to what they must have been able to charge for the phone call, certainly worked out to a substantial loss for them.
