Thirty years ago I visited friends in Annapolis, Maryland USA to set up a big hi-fi audio system and especially to go fishing. Annapolis is home to the US Naval Academy and many naval operations. My friends, all native to the area, gave me a driving tour of the city. I saw antennas like I've never seen before or since. The strangest antenna system, so they told me, was for communicating with submarines. After seeing all the antennas that day, it occurred to me that it must take a huge amount of electricity to keep all that equipment running.

The Annapolis array is Navy radio station NSS, or what remains of it. Most of the towers have been taken down. The remaining towers stand due to nesting protected birds. I think Ospreys. en.m.wikipedia.org/wiki/NSS_Annapolis

I was a CTM from 1973-1979 assigned to the NESSEC Installation Team from 1974-1977 and visited most of these sites during that time. I spent my last 2 years at NSGA Homestead. This video brought back lots of memories!

If you get a chance take a closer look at the Chesapeake base. I trained there, and the direction finding antenna was only one of several interesting antennas. I was told by one of the Navy officers there that they even had a VLF antenna for communicating with submerged submarines there. I think that was the antenna that was almost a mile long and you had to drive over it to get to the pistol range.

After leaving NSWG, one of my shipboard assignments was in radio intelligence on a naval vessel; part of our coordination was with the radio site in IB.

it's Buster Goniometer and his Unfeasibly Large CDDA

Great video, it's nice to have a clear and concise history of these stations. My grandfather worked for ITT in the 60's and was a project manager overseeing the installation of the equipment rooms at Edzell station. I believe he also did the same in Spain and likely some other stations. He spent a lot of time in Guam, Japan and Okinawa. Apparently goniometers were his specialty and he had the nickname "Captain Gonio" - of course none of the family knew any of this growing up, it was all highly secretive and all we knew was he worked on secret government stuff and was traveling all over the world doing who knows what... was grandpa a real life James Bond? We could only guess. What we did know was that government agents would visit the neighborhood and ask the neighbors questions, and some of our phones were tapped. Now that all this stuff is decommissioned and de-classified I'm able to piece together what he actually did and its fascinating.

I had the fortunate experience of being the OPS Tech Section Supervisor from 74 to 78 in Gander. Every so often, during an emergency and the inability to find the civilian antenna maintenance individual, I had to climb those poles to attach the guy cables. It was cold on those fingers, and extremely frustrating if you dropped any of your tools from up there. 😎

My dad even had a radio with SW1 and SW2 switches, which I messed with a lot LOL. Anyway, I remember being able to regularly tune in to a morse code numbers station broadcast. Would that have to be a SW radio? Or could that be any old crappy toy car radio for listening to chart music. This was Midlands UK possibly around '78 - '81when I was around 10 yrs old. I could recite that morse code sequence cos it repeated so often. I listened to a Russian numbers station broadcast which sounded very similar to my memory, (Russian M12 CW on Curt Rowlett's channel). Probably could have been any one of hundreds maybe.

I was stationed at Galeta Island Panama. '83-'84. After Navy left in '95, NSA took it over until '99 when it shutdown completely. I was at Homestead, left just prior to hurricane Andrew.

Does anyone know if there is a video on the ELF transmitter near Clam Lake Wisconsin ?

Great subject. While mentioning maine, don't be afraid to go down the rabbit hole of the VLF/ULF transmitting station at Cutler Maine.

We have a smaller version that appears to be active in Lake County Florida located on private property in the middle of a cow pasture on an isolated dirt road that does have power lines. The government paid the land owner a very large sum of money for the permanent rights to keep the antenna there. No one knows who is using it nor for what purpose.

I had the distinct privilege of being stationed at all four of the Navy's different CDAA sites within my 11 years of active duty between 1972 and 1983. My first duty station was Misawa Japan. We used a three-band AN/FLR-9 array maintained by the US Air Force Security Service. My next duty station was NSGA Azores where it still used the AN/GRD-6 small diameter array. This unit had a motorized goniometer but was originally configured with a manually operated gonio. NTTC Pensacola also had a GRD-6 for training purposes. My next duty station was NSGA Northwest which had an FRD-10 array. I was in charge of the shop that maintained the two goniometers and all of the distribution equipment. The goniometers were really a great piece of engineering! My final tour on active duty was back to NSGA Azores where the GRD-6 had been replaced with the AN/AX-16 Pusher array (made by Plessy in the UK.) It was an interesting time to be involved with Classic Bullseye and I am curious if any other CT had worked with all four CDAAs.

Can you do something about h2s and chain hlome, or even marconi, in North Wales ?

You left out most of the Mediterranean sites except for Rota (Net Control for Med). I remember there were Bullseye/Bulldog sites in Turkey, Italy, and possibly elsewhere. Also, the reason the Canadian sites are still operational is Canada was very interested in tracking fishing ships encroaching in Canadian fishing waters. The Cold War might be over, but Canada still wants to protect their fishing waters. I imagine the reason the US shutdown the project is there are cheaper and better methods today to track foreign ships and aircraft instead of a couple dozen bases with hundreds of sailors stationed at each. Classic Wizard was more accurate anyway; Bullseye/Bulldog was generally considered to be accurate only to within a 1-mile box.

I vividly recall driving up to the guard shack about 850 m from inner reflector of the NSGA Skaggs Island antenna in the late 1970s where my father who was a Navy vet and a ham asked the guard of the antenna's purpose. The guard replied that he thought "it was some sort of nuclear thing". The family turned around and continued to our picnic and the answer was dismissed as silly, but later I learned the site was to be repurposed in the early 1970s for a phased array RADAR to guard the San Francisco area with Zeus and/or related missiles at remote launchers. An arms treaty which limited the number of interceptor warheads caused plans to shrink to just the Stanley R. Mickelsen Safeguard Complex in North Dakota so the answer was less silly than thought. I drove up to the same spot in 2014 but there was a locked gate and later that year the whole access road was blocked. Side note: the first station to receive Sputnik 1 in America was the Press Wireless, Inc station roughly 5.7 km North-East of the Skaggs antenna. That station continued to track later Sputniks for the Hearst Newspaper chain.
