Contrast that to the original Marconi site of WCC on Cape Cod that I visited three years ago. It's now mostly gone except for a small pile of bricks. Much the same for all the other RCA stations, including Radio Central on Long Island.
IIRC Jim, that hunk-o-bricks was all that remained of the power house foundation area. I first started visiting that site in the early 80s when there was a good 30-40' more sand than there was the last time I saw it in '94. At that later date, enough sand had eroded to expose the two easterly tower bases, looking like giant toadstools sticking up out of the side embankment. I actually found a couple of loose bricks in the area over the years that hadn't gotten claimed by the ocean. Also some wood from the old towers. South Wellfleet is probably one of the few instances where nothing could be done to save the site short of moving it like the Cape Hatteras light.
CC-MCC-WCC inland receiving station at Chatham was another wonderful place to visit. I haven't been there since before they closed it in '97 and dismantled/demolished the antenna farm in '99 or so. Every time I went there to visit, it was very quiet and very deserted - from '82 on. No cars parked near the buildings, nothing. Here's a station that communicated with Admiral Byrd's expedition, the Graf Zepplin's around the world flight, the Hindenburg just before its crash, and a number of ill-fated ocean liners, passed countless RCAgrams to passengers and witnessed other memorable events. A modern day ham club works out of the old ops building, wonder if they have any of the old gear still around? CR-88s were still in use in the 60s along with Radiomarine CRM-6As through the 70s-80s.
No idea what, if anything, remains of the Marion transmitter site. There used to be a place called the 'Shortwave Grill' next door. Chatham was the ears, Marion was the voice.
WA2PJP and W2XR have some interesting stories about a similar facility on Long Island and its demise. So much of our country's history passed through these places in wartime and peace, it seems sad that more of it isn't preserved.
I can still remember driving along Rte 28 by Ryder's Cove and seeing the WCC masts and towers for the first time. Ah, the good ol' days....
