Jon Poindexter W5ALC

Technical Systems Specialist, Web Design

I've always been driven by curiosity about how things work. Growing up in Austin, Texas, I was surrounded by technology—my mother and stepfather both worked at IBM. When I was 7, my stepfather left IBM to repair watches and clocks, introducing me to precision manufacturing and repair. At 14, a visit to Farmington, New Mexico sparked my interest in amateur radio, a turning point that shaped much of what followed. I earned my technician license in February 2004 with the callsign KE5ALC.


Amateur radio naturally led me into the open-source community. Both share the same spirit: experimentation, collaboration, and building things simply because they can be done. Linux gave me the freedom to experiment with software, while amateur radio let me experiment with hardware and connect with others who share my enthusiasm for learning.


I enjoy hands-on projects and creating tools that make gathering and sharing information easier. I'm especially passionate about helping people think through problems, explore new approaches, and eliminate obstacles. If you're facing a challenge and need a second set of eyes, I'm always happy to work through it together.

“I have no special talents. I am only passionately curious.” – Albert Einstein.


Since childhood, I have been a very curious person, always tinkering with electronics and radios. My father, a computer engineer, regularly encouraged my curiosity throughout the years. Growing up in Dayton, Ohio, I learned about amateur radio when I was just 9 years old and began studying for the license at that time. Eventually, I lost interest in radio. However, after moving to Colorado and taking up storm chasing in 2023, I obtained my technician license in April of that year, shortly after becoming a certified SKYWARN spotter.


I obtained my amateur radio license to relay observations to the National Weather Service (NWS) during storm chasing. Luckily, my local repeater in Sterling, CO, is part of the Denver SkyHubLink Repeater System. Through it, I began to rely on the Colorado Severe Weather Network (CSWN) to help me understand what was happening with a storm I was chasing, and to relay, via radio, any severe weather I observed for further relay to the NWS.


I joined Big Dawg Northeastern Colorado Storm Chasers (Big Dawg Wx) in late 2023, just before my chasing partner and legendary Colorado Storm Chaser, Dakota McGee, passed away. Big Dawg just recently reached 30k followers on our Facebook page. My specialty with Big Dawg Wx is running all of our social media profiles—aside from storm chasing, of course.


Abraham brings more attention to the value of amateur radio, promoting it and the SKYWARN program, especially within the greater northeast Colorado community. He regularly dialogues with Net Control in the Colorado Severe Weather Room (Reflector xlx303a) during outbreaks and calls in severe storm reports for relay to the NWS. He is the Colorado Severe Weather Network’s Director of Public Relations and Facebook Administrator.


We greatly appreciate Abraham’s talent and expertise on the CSWN Staff!

Terry Koelling AD0A
Terry Koelling AD0A

Weather Information Room/Telegram

During Terry’s growing-up years, he moved around a lot due to his dad’s job. The family finally settled in Colorado, where Terry graduated from high school and attended the University of Colorado in Colorado Springs. He graduated as an electrical engineer and spent the first fifteen years of his career designing instruments in the aerospace industry.


Terry then transitioned into software and worked in the cable television industry, before shifting into data storage as a firmware engineer. Later, he started his own consulting company and worked as a contractor.


He is now semi-retired but plenty busy — Active in their church, he leads the worship production team, volunteers with the Red Cross, and acts as an usher at the Arvada Center. Fortunately, their three children live in Colorado, so they can visit with their four grandchildren regularly. Terry and his wife love the outdoors and still play volleyball.


Terry maintains his ham radio repeater, a Yaesu DR2x at 449.675 (-) DN in Arvada, Colorado. He also hosts the morning Weather (outlook) Information blog on Telegram and takes on whatever else sparks his interest (lately a lot of AI). In addition to this, he is working to get all his photos amassed into interesting video stories, keeping those memories alive. The Koelling’s are looking forward to their next adventure(s)!
