Ham Member Lookups: 47607


My name is Marshall Dias, originally licensed in 2009 as KD0JCV, I became an Amateur Radio Operator with the interest in High Altitude Ballooning. After seeing a news story about 2 students from MIT who created the Project Icarus, I was fascinated with the idea of trying it for myself...

In 2010, I started the iHAB Project – Iowa High Altitude Balloon Project. With the same goals in mind as Project Icarus, my own High Altitude Balloon and Amateur Radio career has taken me places far more exciting than JUST near space. I continue to embrace the many facets of this hobby, and learn something new everyday.


A special thank you to my elmers - Bill Hart (W0NBP) and Terry Fletcher (WA0ITP) for your help, guidance, support, and encouragement through the years, it has been invaluable in making me the ham I am today!

I am very grateful to people like Terry Fletcher (WA0ITP), Jim Kortge (K8IQY, David Cripe (NM0S), the entire 4SQRP gang, for a continuous supply of awesome building projects, toys and support. Without these individuals, QRP wouldn't be what it is today.

Flying exciting Amateur Radio based payloads, like 20M and 40M CW Beacons and VHF/UHF Repeaters. Experimenting with digital photography to produce stunning images from high above the Earth's surface, to capturing amazing hi-def video. The iHAB Team has captivated Amateur Radio enthusiasts, kids, both young and old and ourselves as we have push technology to new heights. We have had the pleasure of partnering with QRP ARCI, Marion Homeschool Assistance Program, and Amateur Radio Clubs to provide a learning experience for anyone who has ever dreamed big!

In 2010, we began a program called CanisterLabs. The purpose of this program is to bring the iHAB Team into the classroom. It gives students, parents and teachers the opportunity to experience Near Space. Using 35mm Film Canisters, students can build mico science experiments, learning how to design, build, hypothesize, and analyze.
We would like to thank everyone who has contributed and supported the iHAB Project!
