Rio ARC K5RGV

Welcome to the Rio Amateur Radio Club!

Ham radio has been sparking curiosity and connection for over a century—from local chats to global contacts. At Rio ARC, we blend hands-on radio fun with a welcoming community, whether you’re a seasoned operator or just radio-curious.

Based in Harlingen, Texas, we serve the whole Rio Grande Valley—from McAllen to Starbase. We’re into all things ham: antennas, POTA, digital, analog, and everything in between.

Want to meet us? Join one of our laid-back breakfast meetups—no pressure, just good food, good stories, and great company. Check our events page for details. Everyone’s welcome!



Field  Day 2025 is Over!

The Rio Amateur Radio Club extends heartfelt thanks to Byron (KI5GNH) and Tom (WT5TX) for their outstanding effort and dedication in setting up multiple stations at Spotted Sea Trout Park in Rio Hondo. Their hard work made this year’s Field Day truly memorable.

We also appreciate everyone who stopped by to watch, support, and lend a hand. Final scores will be shared once they are officially tallied and recorded.

Thank you all for making it a great event!

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

A big thanks to Tom (WT5TX) for introducing something new and giving many of us a fresh and exciting experience in ham radio!

Barry's Corner
Barry A. Boothe, W9UCW

"Over the coming months on this venue, I plan to present a variety of technical pieces and stories from nearly 70 years as an active ham."

There are now thirteen handwritten (they may have originally been typed) articles by Barry, some even featuring pictures! Just check the menu and click on "Barry's Corner" for some informative and entertaining reading.

A Signal from Across the Sea

One quiet evening, Rio ARC member Carlos tuned into 20 meters just for fun. Between bursts of static, he caught a faint but steady voice—it was a ham operator calling from a tiny island off the coast of Japan. Carlos answered, expecting the usual brief exchange of signal reports, but the two ended up chatting for nearly 30 minutes about family, weather, and their shared love of old tube rigs.

Neither had perfect gear or a huge antenna farm—just simple setups and a little patience. But through the magic of the ionosphere, two strangers became friends, 6,000 miles apart.

It’s moments like these that remind us: ham radio isn’t just about the tech. It’s about the people.
