Over 17 years ago, a co-worker of mine at the Apple Store, Shane (later known as WQ3Y) started talking about getting an Amateur Radio License. He had long been fascinated by the idea, and suggested that perhaps a few of us could start a study / accountability group to make the process easier. It didn’t take much to sell me on the idea. As a technology nerd, I’m always on the lookout for new skills and knowledge that might eventually be useful, and understanding something about how the magic of radio worked seemed like a good idea in a world that was increasingly dominated by Wi-Fi, Bluetooth, and cellular networks.

I got a couple of books – one for the entry-level “Technician” license, and one for the next in the series, “General” – and began to study the material. I’m honestly not sure how long I studied, but Shane got his license in January of 2008, and a few months later, I felt like I was ready, too. On a Saturday in late June, I drove up to the studio of WDEL / WSTW north of Wilmington, DE to take my official test at a picnic table in the parking lot along with other hopeful hams.

The few minutes that it took for my paper test to be graded by the 3 volunteer examiners felt much longer. At last, one of them approached me, and gave a late smile. “Do you want to try for General? It doesn’t cost any extra.” That was his way of saying that I had passed. I thought about it for a moment – while I had looked over the General class book, I hadn’t really *studied* it like I had the Technician level material, but I thought it was worth the shot if they were willing to test me.

I took the second multiple-choice test and another anxious wait ensued. Once again, the same man walked back over to me. “Want to try for Extra?”

Now in those days, the highest-level “Extra” class license required a Morse code test. I knew there was no way that I could pass that. And I hadn’t ever considered looking at material as advanced as the Extra test was going to throw at me. I decided not to waste anyone’s time, and took my General class CSCE home.

After a few days, I got an email from the FCC that they had my paperwork and were looking for me to pay the $35 licensing fee. I promptly did, and on July 8, 2008, I was officially licensed as a General class Amateur Radio Operator with the callsign KB3RLM.

I’ll admit – I wasn’t as taken with the hobby at first as Shane was. I was more interested in the knowledge than the practical application. Shane got some radios and antennas for his house. He set up a VHF/UHF rig in his car and experimented with APRS, showing it off to me in the days before Apple’s FindMyFriends app was ever thought of. I thought that part of it was really cool, but I never did any of that. I didn’t buy any equipment at all. I learned about EchoLink – a way to participate in VHF & UHF repeaters over the Internet with a computer – and I signed up for that. I even played around with it a few times, but it always felt like I was cheating somehow. My license came up for renewal after 10 years, and I kept it current with the FCC for address changes and the like, but that was about it. Other things happened in life, and my interest waned.

Fast forward to the summer of 2025, and a short diversion.

My boys and I got a phone system set up at the house, as I mentioned in a previous post. What I didn’t mention was how I got those lovely Cisco phones in the first place. I had found a listing on Facebook Marketplace advertising FREE Cisco phones. A business up in the Philadelphia suburbs had recently removed their phone system and just wanted rid of the desk sets. I called to inquire about getting 5 of them for us to play with and the woman I spoke with sounded disappointed, “ONLY 5? I’ve got boxes of these things!” To make a long story short, I ended up coming home with close to 50 of them, and I’m happy to say that they all made their way to good, nerdy homes.

But before we could do that, we had to clean them up a bit. Isaac especially enjoyed doing this with me. One by one, we powered them up, updated their firmware, connected them to our phone system, and ran through a series of tests. As I poked around the Internet for information about the particular model we had (the venerable SPA525G2) I found out that they were popular on a service called Hamshack Hotline.

This was a really cool idea. It was a service using very similar server software to what we were, but offering it up to ham radio operators around the world for free. It was a way that you could have a secondary means of communication with your ham buddies, while also messing around with how VoIP worked. Since I had a license, I figured, why not try to fire it up on one of these phones? Literally the day after I decided to do this, Hamshack Hotline announced that they were shutting down. Running the service had become too cumbersome. Luckily, a similar (though smaller) service existed in Hams over IP. I immediately signed up for an account.

As I was digging out my license paperwork so that I could complete my application, Isaac was looking over my shoulder. “What’s this radio license thing all about?” He was instantly intrigued. We had a few conversations about it, and his interest only grew. I told him he’d have to learn enough about radio and electronics to pass a license test. It would take some work, but he was up for it. The prospect of learning some science was exciting for him, so we ordered a book and got deep into studying.

Now, there are easier ways to get on the radio if that’s what you want to do. There’s the Family Radio Service (FRS) and CB radio – neither of these requires any type of license, but they are channelized, use FM and AM, and are limited in power to 2 watts and 4 watts respectively. These restrictions really impact your communication options and range. The General Mobile Radio Service (GMRS) is very much like FRS, but with a higher 50 watt power limit. While this increases range, it’s also where the FCC starts to require a license, just without a test. Simply pay a fee and your entire family is covered for 10 years. All of these services require the use of store-bought radios that are approved by the FCC, and are generally pretty easy-to-use.

What makes amateur radio special is that our license requires us to pass a test (or several tests for the higher-level licenses). We have to demonstrate that we have at least some understanding of how all this stuff works. In exchange for that level of knowledge, we are given much more freedom. Ham radio is for tinkerers – part of our mission is to push the art and science of radio forward through experimentation. We are granted privileges on several frequency bands from shortwave all the way through high microwave without being channelized. We are allowed to operate with up to 1,500 watts of power. We can use FM, AM, SSB, Morse code, and loads of digital modes to communicate. And we can design and build our own radios and antenna systems without needing specific FCC approval. Just about the only restrictions we have are that we have to identify ourselves in our transmissions, and we can’t encrypt our communications – everything must be in the clear. And of course, we aren’t allowed to intentionally interfere with anyone else’s transmissions, and we’re expected to know enough to not accidentally interfere either.

One thing we have going for us is that there are so many helpful educational resources for prospective hams these days. Isaac and I not only dug into the book together, but we used the study materials and practice tests at HamStudy.org, and the videos on the Ham Radio Crash Course YouTube Channel. Over the course of a month, Isaac started to get more comfortable with the material, and started doing better on the online practice tests. When he was consistently passing them, I started to look for a way for him to do an official test.

Initially, I was looking for an in-person session just like how I had gotten my license. The ARRL even has a nice search function on their website that can be used to find one. Unfortunately, there weren’t all that many offered in Delaware this past summer, and the ones that were a little farther out didn’t work for our schedule. That’s when I found the WM7X Online Testing VE Team. They have available spots every day, and as long as you can get your computer on a Zoom session, you can do a proctored online test using the same ExamTools system Isaac had been practicing with. Seemed like a good option. We registered on a Thursday morning and Isaac was testing within the hour.

Since he is a kid, the VEs (Volunteer Examiners) allowed me to sit next to him, as long as I remained on camera and didn’t help him in any way. Isaac was definitely nervous to take the actual test, and I was nervous with him. I tried to keep track of how he was doing on the 35-question, multiple choice test in real-time, but I couldn’t tell what the result was going to be. Isaac answered all of the questions, and hit the “Submit” button at the bottom of the page. One of the VEs “graded” the test, and the result popped up on screen: he had PASSED!

The next day, we got the registration fee email from the FCC, and by Saturday morning, Isaac had his license and callsign: KD3BSR. If you’d like to read about Isaac’s experience with getting his license, he wrote about it on his website.

We immediately set him up with his own EchoLink account, and he made his first contact on Sunday morning with N3RY on the W3VPR repeater – which has since become one of my favorite places to hang out.

We soon got a pair of TIDRADIO TD-H3 hand-held VHF/UHF radios, and have gotten familiar with a few of our local repeaters. Isaac really lights up when he gets to be involved in the conversation with the other guys. We’ve also been having fun with amateur radio signals from the International Space Station; decoding some of the SSTV (Slow Scan TeleVision) images they were transmitting in honor of World Space Week 2025.

Seeing the excitement Isaac has about this technology – and also the sense of accomplishment he has in having earned his way into the ham radio club – has been really invigorating for me. He’s so proud of his Technician credential, and I’m proud of him for sticking with it to reach his goal.

His experience inspired me to jump back in myself. I’m happy to say that after Isaac passed, I picked up some study materials – including the EXCELLENT course on W4EEY’s YouTube channel – and was able to pass my Extra exam with WM7X acting as my VEs as well! In the coming months, I plan to build out an HF station that will enable us to make long-distance – and even worldwide contacts.

Isaac is already working on catching up. 🙂

For now, I’ll end the post with the traditional ham farewell: “73!”

Since we have moved to Delaware, one of the places that the boys and I love to visit over and over is the Air Mobility Command Museum at Dover Air Force Base.

For one thing, its a free museum that’s only about 30 minutes away, so it doesn’t take much justification for us. But what keeps us coming back is the staff. The docents are largely retired Air Force folks who love to share the stories of the aircraft they worked on during their military service. They are always so knowledgeable and welcoming – especially on days when they host Open Cockpit events.

Most of the museum’s extensive collection is outside. Favorites there include the VC-9C that served as Air Force 2, the massive C-5A, and the KC-10.

The first time we visited the museum, we got to go inside the C-5A. We entered on some air stairs near the rear cargo door, and I noticed a model of the Wright Flyer hanging from above near the cargo door. I asked the docent about it, and he directed my attention toward the front of the cargo compartment where an American flag was hanging near the ladder up to the cockpit. He explained that the span from that Wright Flyer model to the flag was the same distance as the Wright Brothers’ first flight. Incredible that within the span of just 65 years, aircraft technology had progressed that far. It’s still my favorite story from our visits.

Inside the museum building – which began its life as Hangar 1301 during WWII – the coolest aircraft are the C-47 Skytrain which actually dropped paratroopers during the D-Day invasion, and the B-17G. My wife Emily particularly enjoys seeing that one as her “pop-pop” served as a radio operator on a Flying Fortress during WWII.

As I alluded to, we have been to the museum several times. Some days, it’s “just because,” but we have also made the trip for special events like their Open Cockpit days.

During the summer of 2024, the boys were even able to go to their really cool week-long, half-day summer camp program. They spent a week learning about aircraft, spacecraft, land navigation, and other STEM topics. The highlight of the camp was most definitely a 30-minute ride in a Cessna courtesy of the Dover Aero Club. John took his phone along and got some photos of the ride.

John made a post about his experience with the summer camp on his website last year. Isaac wrote about it, too.

It’s been almost a year and a half since I last posted here. It’s just so easy to use Facebook for “life updates” these days, and that’s where most of my friends and family go to look for that sort of thing. With the hustle and bustle of life, it’s easy to neglect your blog. That said, here’s my attempt at a general life update.

History

I’m still fairly involved with the HMdb. While I’m out and about, I’m always on the look-out for new markers. I’ve really been working to improve our collection of roadside markers from the Delaware Public Archives (whose own online listings of markers are incomplete and rather disjointed). This is a never-ending task as new markers are added, but I’m confident that our listing of these is complete for now.

The database continues to be the first place that I go to research the history of an area – seeing pins on a map just works for my brain with trip planning.

As of today, my contributions are good enough to rank me as 70th all time out of 7,683 individual contributors to the database. I have submitted a total of 583 markers, 1,489 photos, and 412 links to other websites. I’m very proud to be part of the team.

Technology

Sadly, not much has changed in my home lab since the last update. There are of course new versions of software, and a few new applications I’ve been playing with, but the large hardware changes I’ve been wanting to do are still on the back burner for now. I’m hoping that I can return to those in the new year.

Our most significant addition has been a new in-home phone system using FreePBX and several Cisco SPA525G2 desk phones. The boys have really enjoyed being able to help build this and play with it. Once I get some better back-end hardware, I’m planning to hook our system up to the outside world through a SIP trunk with an actual phone number. Stay tuned for more posts about this topic.

Speaking of things that deserve their own posts, I’ve re-entered the world of ham radio. That story will be fleshed-out soon.

Other News

Since he got his own phone last summer, John has picked up an interest in Geocaching. We try to plan an outing for that every month or so, and it’s a good excuse to get outside and move a little while still doing something nerdy. Sometimes, I’m able to get some historical markers at the same time so, win-win!

Also late last year, both of my boys worked through classes at our church and became full communing (and voting) members. It’s fun to watch them grow up and begin to enter adulthood in small ways like that. As rough as these middle school years can be (yes they are BOTH in middle school now) this is also the time when they are truly becoming themselves.

Thanks to some free tickets he got as part of a school reading program, Isaac took me to a Delmarva Shorebirds game this past spring. The boys and I have now been to games at all the Orioles minor league affiliates’ stadiums.

Also coming in a future post: I got a passport for the first time last year! There must have been a specific reason for that….

From my travels, August 5, 2023.

Emily and I had gone up to visit her Nana at the senior living community that she moved in to. We planned to have dinner together in their dining room and just enjoy the company.

As we were waiting for our food, I noticed a series of prints hanging on the wall depicting various aspects of the papermaking process. Some of the prints were photos and maps labeled as from the “Nonantum Paper Mill”. It piqued my interest because of the excellent lecture from Scott L. Mingus that I attended a few years ago on the History of Papermaking.

The three of us got to talking about it at dinner, and the ladies told me that the old mill was nearby on the aptly-named Paper Mill Road. Emily agreed to drive over to check it out when we were finished with our visit.

The City of Newark converted the site into a park several years ago. The mill had closed down in 1999. None of the old buildings still exist, but I think the mill race is still there – I need to go back to investigate further. A wayside marker told the story of the mill – and I was able to add it to the HMDB during my visit.

Most notably, during WWII about 50% of the output of the mill was used by the United States Federal Government or for lend-lease. In fact, the paper that the Japanese Instrument of Surrender was printed on was made right there at that now-unassuming spot in Newark, DE.

I feel like I say it all the time, but history is all around us if you give yourself the chance to stumble onto it.

From my travels, February 4, 2023.

Several months back, a good friend of mine who had grown up in Delaware, suggested that I check out the John Dickinson Plantation. We had a free afternoon, so it seemed like a good time to explore a bit.

Dickinson was an interesting guy. He is one of the rare founding fathers to have participated in all three of the important early documents: the Declaration of Independence (though he refused to sign it), the Articles of Confederation, and the Constitution (which he signed as a representative from Delaware. A native Marylander, he was among the wealthiest men in the colonies, with holdings in Pennsylvania as well. He was a prolific writer, but seemed to hold a more moderate view than some of the others – perhaps because of his Quaker beliefs. He preferred the idea of a negotiated settlement of the grievances that existed with the British crown. Toward the end of his life, he expressed limited abolitionist sentiments, eventually freeing all his slaves.

The historical site here consists mainly of the mansion on the property. There is a small visitors center with a very sparse museum, though the introductory film was good. One of the more bizarre aspects of the site is how it is affiliated. Up until the 1990s, Delaware had no NPS sites. There was a push to create what became First State National Historical Park by involving the NPS in a few of the state historic sites. There were no NPS employees here – it’s primarily run by Delaware, but they offer a limited Junior Ranger program. There was no book – simply participating in a tour earns the badge. They did have a few activity books about sounds in nature, so we took those, but that part of the park experience seems a little disjointed.

Moving on to the main house, the tour was interesting, but not as impressive as some of the other founders’ homes. For one thing, this was not Dickinson’s main residence, but I also think this was due to his Quaker lifestyle. Despite his wealth, he attempted to maintain a plain, modest lifestyle. One of the more interesting things that the tour guide pointed out is that his wealth was displayed in subtle ways in the home. They had extremely high ceilings, and portraits of the family members included their hands – notoriously hard to paint, and thus much more expensive.

In the end, we learned quite a bit about this founding father, and the boys got their First State Junior Ranger badges. It was a good use of a few hours.

From my travels, December 4, 2022.

It’s been on my radar for a while to check out this small park that has some interesting historical connections. As we were on our way home from visiting family in Newark, DE, we decided to make a quick stop to check it out.

The main attraction that day was the dog park, which was wooded, but not very well maintained it seemed. There were just a few other dogs there, and our dog, Sallie seemed to enjoy herself. It was our first time taking her to any kind of off-leash area like that, so I don’t think any of us knew what to expect.

Farther up the hill, there is a collection of wayside markers discussing the geologic history of DelMarVa, the Pencader Hundred, the Battle of Cooch’s Bridge & the Philadelphia Campaign, the historic iron mining operations here (hence, the name of the hill), and Isaac’s favorite: the New Castle & Frenchtown Railroad. He insisted on reading the entire marker out loud by himself. It was actually really nice (if not a bit cold that day).

Prior to the Battle of Cooch’s Bridge, Gen. George Washington and other officers observed the British landing at Elkton, MD from atop this hill. Some fighting also took place along the slopes.

From my travels, September 5, 2021.

Since the boys and I had started hanging around in Delaware more, I thought it might be good to check out some of the local historical sites. Emily had visited the Old State House before, and thought it would be a fun outing, so the next time we visited with “Nene” and “Baba” we took a short drive down to Dover.

The site was originally a smaller 25′ x 25′ courthouse. That building was where the Declaration of Independence was first read aloud in Delaware – the spot is marked by a monument out front. Downstairs in the “new” building served as a county courthouse originally, and the House and Senate met in chambers upstairs. Both of those meeting rooms were surprisingly small – the Senate only had 9 members back in those days, while the House had 21.

The building has been beautifully restored. They even let us sit at the legislative desks – super cool for the boys. Each desk had the name of a member of the legislature from the 18th century, with a short biographical sketch.

Our tour concluded in a room upstairs where some Underground Railroad and abolitionist history was shared.

It was a very nice presentation and tour – especially considering that it was free.

From my travels, July 27, 2020.

With my recent interest in 19th century industrial history – especially where it relates to the Civil War – the Hagley Museum was an obvious place to check out. Because of the partial closures caused by the COVID-19 pandemic, we were also able to get discounted admission. The boys and I planned a visit, and my mom even came along, too.

The museum preserves the site of the original du Pont gunpowder mill along the Brandywine. Many of the old industrial buildings there still exist, and even the water-powered machinery still operates. The mills where the gunpowder was actually ground and mixed were 3-sided buildings with thin metal roofs, so that any accidental explosions would be directed toward the river and not cause permanent damage. There were very strict rules for the employees regarding flammable materials, as you can imagine.

During the Civil War, Delaware was – like Maryland – a state with divided loyalties. The du Pont family lived and worked in the area around the Delaware / Pennsylvania border, so they were strongly pro-Union. Several of the men in the family served in military roles. One of the docents at the museum told us that something like 60% of the gunpowder used by the Union during the war came from these mills. It’s staggering to think about – especially considering how peaceful the place is today. Nature lovers would find plenty to do here as well between the gardens and the lovely views of the Brandywine.

Besides all the cool 19th century machinery, the coolest thing we got to see what the demonstration of the gunpowder testing rig. This was a little apparatus that would show how much force the gunpowder released when it was ignited, and was apparently used as a tool by some of the company’s salespeople.

In the end, it was a good day and an awesome museum. It’s the kind of place that I’d like to visit again in the future.

Even before I moved to Delaware, I had my eye on a visit to what I had heard was an excellent mid-19th century, Third System fort that sits on a small island in the middle of the Delaware River, appropriately named Fort Delaware. Back on May 25, 2019, my boys and I made our first trip over to Pea Patch Island to take in the sites of this wonderful old defensive structure. We have since returned a few more times – it’s a really nice experience.

Today, the island and fort are contained within Fort Delaware State Park, and park staff engage in living history presentations on the island as if it was 1864. Most everyone on the island is “in-character” demonstrating various aspects of life in a coastal fortification turned prison during the Civil War.

Since the fort is located on an island, the only access is by ferry boat from Delaware City. It also operates seasonally, shutting down visitor access between October and April. We bought our timed tickets in advance online, but I think it is also possible to get walk-up tickets from the gift shop. After a quick stop at the restroom, we were ready to board the Delafort for the 10-minute ride over to the park.

Once the ferry docks on the island, a tram takes visitors across the marshy part of the island over toward the historical fort. An audio presentation during the ride talks about some of the history of the island, as well as describing some of the wildlife that can be seen in the marsh as you go by. Eventually, as you make the transition to dry land, the massive fort comes into view.

Built with the intention of defending Wilmington and Philadelphia from naval attack, the fort was completed in 1859 – just in time to be garrisoned at the outbreak of the Civil War. Like many of the Third System forts, Fort Delaware went through a series of Endicott conversions in the late 1890s to install larger caliber guns in huge concrete emplacements. The remains of the Endicott batteries can be seen on the south side of the island near the modern restrooms, and immediately to the right as you enter the fort. These days, the concrete structures serve mainly as bat habitats.

Every time we have gone, the interpretation of life at the fort has been wonderful. The staff does an excellent job of making the place feel alive as you tour through the various areas within the fort. Favorites for us have been the laundry, mess hall, and blacksmith shop.

But this was a fort after all, so the real draw is the artillery! Sadly, there isn’t much here in the way of guns, and I believe that what they do have are reproductions. They do a LOT of artillery demonstrations here and it’s generally not safe to do those with weapons that are over 150 years old at this point. A favorite memory for me is from our first visit, when the boys were able to man one of the guns themselves and participate in a firing drill.

As cool as the guns and casemates are, none of the fort’s defenses were ever tested by an enemy in any era. The main Civil War story here is of the island’s use as a prison camp. Thousands of captured Confederates were confined here. Many died, and there were even a few daring escapes that took place. At the height of it, there were dozens of prison barracks built outside of the fort walls for enlisted men. Captured officers were generally kept within the fort itself. The park has rebuilt one of the barracks from a set of original plans to give visitors a feel for what the conditions would have been like, but it doesn’t do justice to the scale of the prison population that was kept here.

As a fort nerd, I really enjoy going to Fort Delaware. Between the ferry ride and the in-character interpretation of the place, each visit is a true experience. And the fort is in terrific shape – so many of the Third System forts have been messed with over the years – with some becoming almost unrecognizable after going through Endicott conversions. Seeing one that is still at its original height and with many of the interior structures still intact is a real treat. I can’t wait to plan my next visit in the spring.

In the lead-up to the Battle of Brandywine, a relatively small action took place in Delaware at Cooch’s Bridge. So far as I know, it was the only battle to ever take place in Delaware. So when I had to run some errands in nearby Elkton, MD a few years ago, I felt like this site was worth a stop. It’s certainly easy enough as the field is not far from the first exit in Delaware along Interstate 95.

There is a small park here on the American side, with lots of really great wayside markers describing historical topics beyond just the battle that happened here. Recently, the State of Delaware purchased the Cooch family home, with an intent to make a historical park out of it. I’m excited to see what happens there. You can also find some roadside markers in the area that describe the various phases and positions of the battle. For a small field, it is very well-marked!

There is a large stone monument to the battle located along Old Baltimore Pike, but there is nowhere to safely park to examine it closely. Sadly, I could get close enough to notice that the base of the monument is surrounded by 4 Civil War-era Naval Parrott Rifles, so that is a bit of a head-scratcher.

All-in-all, it’s a very nice, well-monumented field given it’s small size and relative obscurity. I heartily recommend a visit if you’re ever in northern Delaware.
