Sweat, Signals, and History: A POTA Activation from the Battleship North Carolina’s Radio Room!

Those of you who know me know that I’m a huge World War II history buff. Ever since I was a child, I’ve been fascinated by the stories of bravery, sacrifice, and technological innovation that defined this era.

That’s why the activation I performed on Tuesday, July 9, 2024, was very special.

I activated the Battleship North Carolina from inside the ship, using a modern transceiver, and one of the original vertical antennas mounted on the ship.

The Battleship North Carolina State Historic Site (US-6831)

The Battleship North Carolina is a World War II-era battleship that served in the United States Navy from 1941 to 1960. It is currently a museum ship in Wilmington, North Carolina.

The ship was launched in 1940 and commissioned in 1941. During World War II, it served in the Atlantic and Pacific theaters, participating in several major battles, including the Battle of the Atlantic and the Battle of Iwo Jima.

The Battleship North Carolina was decommissioned in 1960 and donated to the state of North Carolina in 1961. It has been open to the public as a museum ship since 1962.

Growing up in North Carolina, I’ve always considered the Battleship North Carolina the icon of Wilmington. You can’t cross the Cape Fear river and miss this brilliant bit of naval history–it’s so prominent and accessible.

I had not actually toured the battleship since I was a child–some 40+ years ago. Last week, however, our family spent the week in Wilmington and the battleship was first on the to-do list.

Azalea Coast Amateur Radio Club

A couple months ago, I mentioned to my buddy Bob (K4RLC), in passing, that one of my daughters was attending a week-long residential program at NC State University while the other daughter would be attending The University of North Carolina Wilmington. My wife and I would stay in Wilmington for the week and I would somehow love to activate the Battleship North Carolina for the POTA program.

Fortuitously, shortly thereafter, Bob attended a presentation about the Battleship North Carolina by Mike Hartmann (NI2S) at a radio club meeting in Raleigh. Mike is with the Azalea Coast Amateur Radio Club, the caretakers and curators of radio central in the battleship.

Bob put me in touch with Mike who then graciously accommodated my schedule, even though it required his presence throughout the activation.

Mike did make it clear that the radio room is three decks below, has no air conditioning and is a proper “sweat box.” Turns out, too, that the week we were in Wilmington coincided with a bit of a heat wave which was affecting much of the eastern US. Because of this, I asked if we could meet on Tuesday, July 9, 2024, at the earliest possible time–8:00 AM, when the museum opened.

It was a beautiful morning and I arrived on site perhaps 15 minutes in advance. I needed to pull my camera gear out of the car and allow some time for it to adjust to the humidity (which was extremely high).

I thought my lens had finally acclimatized when I started the video before Mike arrived, but it turned out the lens was still a bit foggy for a minute or two.

Mike arrived and we walked into the ticket booth where I purchased my ticket. He then led me onto the deck and into one of the roped-off entrances to the lower decks.

He kindly allowed me to film walking through the ship into the radio central area. I’ll admit that it was difficult for me to keep my attention on the camera as I was walking through a ship I remembered from my childhood! Since my video is real-time, real-life, you experience it with me–I didn’t check out the ship in advance.

I was amazed at how much of the ship was open to the public and in superb, original condition.

In radio central, Mike allowed me to peek behind some of the closed off sections with my camera, so you’ll get the follow along with me.

What I didn’t realize was just how much signal intelligence was happening on a fast battleship like the USS NC.

There were rooms dedicated to listening posts, decryption/encryption, and sharing of intelligence. This was all so fascinating and enlightening.

Next, Mike opened up the actual radio room where an Icom IC-756 Pro III was hidden in one of the original ship radio desks. This being a museum, all modern gear was hidden as well as possible.

Mike was right about the room being a sweat box–even in the early morning, it was pretty hot and humid in there. Fortunately, he had two fans he turned on and pointed at us.

The view from my operating position.

Mike set up the IC-756 Pro III by connecting it to a power supply, then attaching a Bencher paddle.

The vertical–again, one of the original Battleship North Carolina antennas–also required a little bit of matching for 20 meters.

Any movement of 10 kHz or so, required engaging the 756’s internal ATU.

As I set up the camera and made a comfortable operating position, I realized just how noisy the room was with the normal ship sounds (it has its own fresh air ventilation system) and the two fans running full-bore.

I set up my wireless mics–one on me and the other inside the portion of the desk that housed the radio.

In truth, I wasn’t confident the audio would work out at all. First thing I did when I made it back to the house that day was to check the audio–turns out, it came out pretty darn well all things considered.

In fact, the audio in the video was much better than my own two ears experienced while operating. Having one of the mics much closer to the speaker and protected from the wind blowing really made a difference.

Case in point: In the video, you’ll see I struggled to copy OE6GND–his signal was weak, but I copied it first go when I listened to the video.

I had scheduled my activation on the POTA website in advance. I was so pleased I did this because, three decks below in a battleship, there’s no hint of mobile phone service.

I was a little concerned that 20 meters might not have much life that early in the morning and I was also concerned that propagation might have been poor. Mike had mentioned that they had only recently operated a special events station (13 Colonies, if memory serves) and they struggled to make any contacts.

I started calling CQ POTA and my fears quickly dissipated–the contacts started rolling in!

Here’s the funny part: I got so into the moment, I never thought to check the power setting on the IC-756 Pro III until well into the activation. Turns out I wasn’t QRP at all–I was running a full 100 watts.

That was easy to justify, though, because even though the Battleship NC has guest operators, not all are doing it for the POTA program, so this certainly cast the signal as far as I could. That said, I couldn’t really tell a difference between the contacts I made running 100 watts and running 5 in CW.

All told, I logged 55 stations in 58 minutes. The contact rate could have been higher, but the fan noise, while essential for comfort, made it challenging to hear weaker stations. Listening to the video now, I can hear stations I couldn’t easily hear in real-time.

I could have stayed in the ship operating for another hour or two quite easily, but I didn’t want to impose any longer on Mike’s time especially as the day progressed, it got hotter (high that day was almost 100F/37.5C not including the heat index) and more guests started making their way through the lower decks of the ship.

Commemorative certificate and QSL

After the activation, Bob handed me a certificate memorializing my Battleship NC activation and also one of the QSL cards they issue.

Exploring the Battleship

After the activation and after I put my gear in the car, I took a full self-guided tour of the battleship. I only had about one hour or so to tour the ship and I wouldn’t have the opportunity to read each sign I passed, so I took a lot of photos thus allowing me to catch up on the reading later.

The following Saturday morning, I ended up taking one of my daughters to the Battleship NC for another full tour. We had a few hours at our disposal that morning before picking up her sister at UNC Wilmington. She enjoyed the tour as much as I did.

If you’re ever on the coast of North or South Carolina, I strongly suggest you check out Battleship North Carolina and the city of Wilmington. Allow a good three hours to tour the ship if you can and, if it’s going to be a hot day, I recommend starting the tour as the doors open at 8:00.

Thank You!

None of this would have been possible without Bob (K4RLC) putting me in touch with the Azalea Coast Amateur Radio Club, especially Mike (NI2S), who went above and beyond to accommodate my vacation schedule and meet so early on such a sweltering day.

Thank you so much, Bob and Mike.

This was a dream come true for this radio enthusiast and WWII history buff!

And Thank You, Supporters!

I mention in the video that Patreon and Coffee Fund  support actually paid for this vacation with my family and even the tuitions for the residential programs my daughters enjoyed at NCSU and UNCW. After I pay the bills for running my sites and producing videos, the rest goes into my family fun account so we all get to enjoy the fruits from this labor of love.

Also, the Patreon platform connected to Vimeo makes it possible for me to share videos that are not only 100% ad-free but also downloadable for offline viewing. The Vimeo account also serves as a third backup for my video files. This has become an invaluable archive for me.

Thank you, again, for spending part of your day with me and I hope you have a brilliant–radio-active–week ahead!

Cheers & 72,
Thomas (K4SWL)

  1. Thomas, fantastic! I’m so happy that you could have the NC Battleship tour & radio ops. Your joy and exuberance of being there comes through greatly in the article, and the wonderful photographs. So glad that Mike and the local club could arrange this for you. We’re camping in Roan Mountain Tennessee, so I’ll have to wait till I get back to watch the video but I’m very happy for you. Hope your daughters enjoyed their college experiences as well as touring battleship with you, which will be memorable for them. Thanks for the wonderful write up.

  2. I share your passion for WW2 history. A little over 20 years ago I had the good fortune to be invited to operate the Museum Ships weekend from the radio room of HMCS Haida when it was moored in Toronto. I too earned a certificate to commemorate the event that I treasure to this day.

  3. I’m a retired Navy Flight Officer who flew off of 5 different Aircraft Carriers the last being Eisenhower. Recently I was able to do a self-guided tour of the Alabama. What a grand old ship. I was sad to see that all of the compartment nomenclature was painted over, easy to see why. There was no crew aboard that needed this information to function.

    I have always believed that a ship was an impressive creation but, nevertheless, just a well-designed piece of steel. When the crew is aboard it’s a functioning war ship ready to execute the will of this country wherever it can float. It’s powered by oil but runs on human sweat and lots of it. Many happy memories.

    1. Thank you for sharing this, Bob. I would *love* to tour an aircraft carrier someday. Until then, I do so through YouTube channels. 🙂

  4. I suspect the inert gas around the feed line is nitrogen, which is inexpensive and very dry. Dry gas under low positive pressure keeps the humid air out of the chamber where condensation could cause problems.
    Excellent video.
    I wonder who maintains the antenna.

    1. Very good point–I bet you’re right!

      I’m not entirely sure who maintains the antenna. I know the radio club maintains much of the radio central area, but I’m not sure if they handle the antenna.

  5. What an extraordinary activation on such an historic ship! Years ago I took my children on the USS NC tour while in Wilmington one Spring Break. They were absolutely fascinated with the ship and its history. Upon returning home, the boys eagerly told their grandfather, my dad, about their adventure. Dad served in the Royal Canadian Navy from ‘42-‘45 on a much smaller ship. He was all ears! I had hoped that this past June, while sailing north on the Intracoastal Waterway that I’d be able to make a return visit to the USS NC. It wasn’t to be, but this thorough report, photos and video more than makes up for it!

    1. Thank you, Rod. You know, you can always find another excuse to visit the coast of NC and get more USS NC time! 🙂

  6. Did you make the struggle into the big gun turrets? It seems like you are tall like me, it was quite a squeeze. Nice reading about your POTA activation. Very historic next to all that gear from the war years. Keep up the good work.
    Bob KV4JO

    1. I did. I’m only 5’11” but found it pretty darn tight in there. Did it twice, in fact: the day I did the activation and video, then a few days later when I toured the ship again with my daughter.

  7. Great video! The “stairs” are called ladders and when the messages were sent via the pneumatic tubes, the RM said to the station where it was going, “bunny on the hop”. When the capsule got there, the station said “Roger Rabbit!”

  8. Great article. When I was in the Army I trained on a similar encryption machine that was similar to the German Enigma. It had 7 wheels and they could be altered by rotating them about themselves. After setting up would type 45 Ls and the letter combination 36-45 was on the key for setup and if the setup was correct it would agree with the print out. Training was in room with no windows, had screen to prevent external monitoring and door was a vault with combination and turning wheel to unlock as would be in a bank vault. Never saw the machine after the day of training. Yes operating from a ship like this would be a joy. Have seen others using the ship’s WWII radios. 73, ron, n9ee

    1. Wow–that’s fascinating, Ron. I find those mechanical encryption machines fascinating.

  9. Great Fun and history

    I have enjoyed various visits to Battle Ships so added this to my list

    Out in the sun swabbing decks or in the bowels with headphones on…..I would rather be in the radio room sweating buckets

  10. Hi Thomas – nice story!

    A group of us operate from the HMAS Vampire located at the Australian National Maritime Museum in Sydney – callsign VK2VMP. Operating hours are usually between 20.30 and 01.00 US Eastern at this time of year.

    The Vampire is a Daring Class Destroyer of the Royal Australian Navy in service from ’59-’86.

    We mostly operate on 15, 20 and 40m using SSB, FT8 and CW. Find our email on the ship’s (or my) QRZ page to line up a sked if you’d like to work this piece of maritime history.

    1. Oh brilliant! I may reach out…or better, I might connect when I visit Australia in the future!

  11. We’ll make a sailor out of you yet! What a great report… Thanks for pounding brass and activating such a great ship.

    I’ve logged several contacts from USN Museum vessels over the years. It almost seems a duty for the Ham community to keep them ‘On the Air.’

    Thanks Thomas!

    1. I agree and I love seeing tech history that is still fully operational and well-maintained.
      Thank you, Rand!

  12. That was a great read Thomas! I did wonder if you’d end up as a QRO op, and you did.
    Last time we were in London, we visited HMS Belfast, which is moored next to Tower Bridge. It is a fascinating place and well worth a visit. The HF radio room once had an operational amateur radio station, but sadly this is no longer in place.
