It’s not every day that I get the chance to do a POTA activation from the radio room of a battleship. But thanks to the Azalea Coast Amateur Radio Club, I was able to do a POTA activation of US-6831 from the radio room of (BB-55) USS North Carolina in Wilmington, NC.

If you would like the chance to be a guest radio operator for the BB-55, check out http://ac4rc.org to set up your activation.

The below-deck self-guided tour takes you through Radio Central. The radio room that the radio club utilizes can be seen from Radio Central; however, it is separated from public access by a clear plexiglass bulkhead door. Because the public can watch from the other side of the glass, be aware that it can be very noisy.

To make things more distracting, there is a loudspeaker in the radio room central playing pre-recorded Morse code for ambiance.

Radio Central is located a couple of floors down in the belly of the iron-armored beast, so be sure to schedule your activation on the POTA page. There is no cell phone reception below decks.

The radio club has an IC-756 Pro III available for use. I am not sure about the status of the other WWII vintage radios. I definitely recommend you bring your own key! They had a Bencher paddle thrown in the filing cabinet; it was not usable due to the contacts being bent way out of position. Fortunately, I brought my BaMakey TP-III key with me. If you are using a 3.5mm stereo plug, make sure to bring a 1/4” plug adapter for use with the IC-756 key/headset jacks.

The radio club has the IC-756 and external tuner hooked up to one of the battleship’s original long wire antennas. During the activation, I only operated on 20M. I did attempt to tune 17m and 15m, but I was unsuccessful in getting a match. However, that may have been operator error on my end since I was unfamiliar with the radio and that particular external tuner.

After a minute or so of calling CQ, the Reverse Beacon Network did its magic, and I was blown away by an insane pileup. I realized that I am used to operating QRP with somewhat compromised antennas. In sheer panic, I started looking to see how to turn the power down from 100 watts to, say, 2 watts!!!!

In that moment, I saw a vision of a seasoned Navy Radio OP sitting beside me. He reached over and smacked me on the back of my head and said, “Listen, kid, you’re not some hippie tree hugger operating QRP on some windswept mountaintop. You are operating from the battleship USS North Carolina. She has participated in every major naval offensive in the Pacific area of operation during WWII. Now stand tall, run full power, and work ’em all!”

With that old-school counseling session complete, I began to work the pileup. After being on the air for one hour and fifty-three minutes, I worked 67 stations, with two duplicates and one busted call sign (that I know about). Eventually, no one responded back to my CQ, and I sent “Last call fer POTA de N4MJL” twice. After no one responded to my second message, I quickly sent QRT and started breathing again!!!!!!

In addition to working SA4BLM from Sweden, one of the coolest contacts I got that day was from my dad, AC0UT, located in Missouri.

It’s not every ham that can say that their dad called them using CW while on a battleship.

CW actually runs in my family. I am a third-generation CW op. Continue reading Three Generations of CW Ops: Battleship North Carolina Activation and a Family Legacy →

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.

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