Rio ARC K5RGV

Welcome to the Rio Amateur Radio Club Website!

Amateur radio—often called “ham radio”—has been connecting curious minds since the early 20th century, when tinkerers and innovators began using the airwaves to communicate across towns, states, and eventually continents. What started as a hobby for radio pioneers has grown into a vibrant, worldwide community. From emergency communications during disasters to friendly DXing with operators halfway around the globe, ham radio continues to blend hands-on technology with the thrill of making contact. Whether you're a seasoned operator with years of call signs in your logbook or just beginning to wonder how radio signals can bounce off the ionosphere, the Rio Amateur Radio Club (Rio ARC) is the perfect place to connect, learn, and have fun.

Rooted in the Heart of the Valley

We’re proudly based in Harlingen, Texas—right in the heart of the Rio Grande Valley. This region has long been a crossroads of cultures and commerce. Once a hub for Spanish exploration, the Valley grew with the arrival of railroads in the early 1900s and became known for its rich agriculture, military heritage, and vibrant binational ties. Today, it’s home to a unique blend of traditions, languages, and landscapes that mirror the diversity of the amateur radio world itself. Our club welcomes members from McAllen to Brownsville, South Padre Island to Raymondville, and yes—even from the launch pads of Starbase. With its open skies and open arms, the Valley is an ideal place to explore the many paths ham radio has to offer.

More Than a Hobby—It’s a Community

At Rio ARC, we’re just as excited about SWR meters and signal propagation as we are about community and camaraderie. Ham radio is our shared passion, but friendship is what keeps us coming back. Whether you're into antennas, Pico Balloons, SOTA (Not too many of these around here), POTA, BOTA, or casual rag-chewing, you’ll find fellow enthusiasts ready to talk shop or lend a hand. We welcome everyone—newcomers, seasoned Elmers, DIY tinkerers, digital mode lovers, and analog die-hards alike. Above all, we believe in supporting each other and having fun while we do it.

Start Your Day the Rio ARC Way

One of the best ways to get to know us is at our twice-weekly informal breakfasts. We gather over coffee, good food, and easy conversation—no pressure, no presentations, just good company. You don’t have to be a member to attend. Just bring your curiosity and maybe a story about your latest build or your favorite contact. Check out our “Future Events” page or club calendar for the latest schedule. Whether you're here to learn, teach, or simply listen in, we’ve got a seat waiting for you.



Pico Balloon Serial 6 Launched

This morning, June 7, 2025, Tom (WT5TX) boldly launched Serial #6—the latest brave little pico balloon in a long line of floaty pioneers—on what we can only hope becomes a dazzling, globe-hopping escapade. The launch was executed from the world-renowned (okay, locally renowned) Rio ARC Balloonport, which also happens to be a patch of land southeast of Harlingen, TX. Tom was joined by Scott (KI5UER), who provided both moral support and wind commentary.

Tom reported that the wind had quite the attitude this morning—gustier than a politician in an election year—and shoved Serial #6 northward with some enthusiasm. Liftoff occurred at approximately 7:30 AM Central Time.

As of 10:15 AM, however, the high-flying adventurer has yet to check in. No pings, no tweets, not even a “Wish you were here.” But we're hopeful that soon, Serial #6 will chirp its way into our radios and our hearts.

Hang in there, little buddy. We’re listening.

Pico Balloon Serial 6 First and Last Update

Well, it looks like Serial #6 has already wrapped up its short-lived sky-high adventure. It soared to an impressive 37,000+ feet by 11:30 AM yesterday—just four hours after launch! Up there, the temperature was flirting with 0°F, the sun was beaming in at a 70° angle when it first started transmitting, and the little balloon was sipping a healthy 4+ volts of power.

Right after liftoff, Serial #6 took off heading due north. Its first ping came from about 5 miles northwest of Raymondville—so it covered roughly 30 miles before saying its first hello. Then it wandered on a gentle zigzag down toward Starbase. Its final check-in was last evening, about 5 miles northeast of Starbase, Texas. Winds at altitude must’ve been taking it easy that day!

But from the very start, we had a hunch that Serial #6 might be feeling a bit under the weather. It started climbing like a champ at 120 feet per minute, but then… it hit the pause button. After hovering at altitude for half an hour, it slowly started to descend. By 12:28 PM, it was sinking at a steady 100 to 150 feet per minute. The final transmission came in at 4:00 PM, reporting an altitude just north of 11,000 feet. At that point, it was clearly heading back to Earth—and there was no stopping it.

This flight featured a 60-inch balloon designed to cruise higher than its predecessors. But alas, it seems a sneaky little leak had other plans. That tiny flaw cut the journey short, well before we were ready to say goodbye.

Farewell, Serial #6—you flew high, if only for a little while.

Pico Balloon

The first Rio ARC Pico Balloon (Serial #1), sponsored by Tom (WT5TX), was launched southwest of Harlingen, TX, at 0800 local time on March 21, 2025.

Unfortunately, the balloon stopped transmitting on the morning of March 25, 2025. However, before going silent, it covered an impressive distance and provided valuable data:

Total distance traveled: 5,862 miles
Last reported location: Mauritania, Northwest Africa
Average speed: 81 mph
Fastest speed recorded: 127 mph
Slowest speed recorded: 35 mph
Average altitude: 34,826 feet
Highest altitude recorded: 35,630 feet
Coldest temperature recorded: -29°F
A big thanks to Tom (WT5TX) for introducing something new and giving many of us a fresh and exciting experience in ham radio!

 A personal look at Field Day

The generic description of “field day” is widely diverse but it usually mentions these things .

: a day for exercises or maneuvers
: an outdoor meeting or social gathering
: a day of sports and athletic competition
: a time of extraordinary pleasure or opportunity

The ARRL says this about our Ham Radio Field day,“Field Day is ham radio's open house. Every June, more than 31,000 hams throughout North America set up temporary transmitting stations in public places to demonstrate ham radio's science, skill and service to our communities and our nation. It combines public service, emergency preparedness, community outreach, and technical skills all in a single event. Field Day has been an annual event since 1933, and remains the most popular event in ham radio.”

My personal knowledge of Field Day began in Joliet Illinois the year I was licensed WN9UCW. I received the call in August of 1954, seventy one years ago. I was thirteen. That next June I was able to attend the local club’s field day on “Moose Island” in nearby Channahon , Illinois.

The club was the “Joliet Amateur Radio Society” fondly called the “JARS.” They sponsored the ”Code School” that helped me get my novice license,I learned that the JARS was very serious about the competitive aspect of Field Day and that they were usually in the top few of the one hundred or so clubs in the four transmitter class, and sometimes they were number one.

At club meetings that spring I observed the members getting organized for the June event. By April or May they had four members who would be captains of the four stations that would be set up. They worked out the bands and modes to be covered by each station and decided what multipliers they would seek. For instance, if they chose a low power limit like 30 watts, they had a significant multiplier for every contact made compared to the high powered stations. They also plotted the layout of stations and antennas in the allowed 1000 foot circle limit.

The captains of each of the four positions were responsible for having the equipment, some sort of an enclosure and an operator as well as a logger for all twenty four hours beginning midday Saturday. This was before computers were available and everything was recorded on paper and pencil. Loggers were also responsible for identifying duplicates so that no time was lost on contacts that wouldn’t count on the final score.

Other persons were assigned to putting up antennas and attending to the generator. Someone with experience in food was assigned to provide meals for the whole crew. The JARS had an ex Navy cook as a member who filled the bill perfectly.

A good time was had by all and by Sunday evening everyone was as exhausted as could be as they made their way home. Personally, I was involved in JARS field days for about twenty years and have fond memories of them all. Interesting things were tried to improve efficiency like mounting a transmitter in the center of an elevated dipole to reduce losses in coax transmission line. That made quite a difference on the higher frequency bands and certainly contributed to those fond memories.

I hope you all have a great time with friends at Field Day.

A Funny for June

Here’s a classic real‑life ham radio mishap that always gets a laugh—it even made Reddit:

“An old timer in my club back in Ohio told about one of his first CW contacts. He let the other operator know he was fairly new, and every time the other guy sent ‘dit‑dit‑dit’, he replied with ‘dit‑dit‑dit’… The senior ops thought he was sending Morse code back and forth—but he was just repeating the side‑tone from his keyer!”

In other words, the newbie was imitating the beep in his own headphones, thinking it was the other station's signal, so he’d echo it back. The seasoned CW operators literally thought he was performing a Morse symphony—until they realized he wasn’t actually transmitting at all!

That moment of realization—when they figured out he was stuck in a loop—is one of those quintessential ham-radio “did I just hear that?” moments. It’s a wonderful reminder of how eager beginners can be, and how funny mistakes often make the best stories in our tight-knit hobby. Want to hear more like this? I can dig up more tales or even some video highlights if you’d like.
