Ham Member Lookups: 2023


I’ve been licensed since May 1992, first as KB5SRY, followed by KK5AJ, and as AJ5W for the past fifteen years. 

In 1996, I was the recipient of the ARRL Scholarship Honoring Senator Barry Goldwater, K7UGA.  At the time, this was the ARRL’s most prestigious scholarship for college-bound amateur radio licensees, and it was an honor to be selected as a recipient.  That same year, I also received the Bill Moore (KF5DL) Memorial Scholarship awarded by the Green Country Hamfest.  I attended the University of Tulsa, graduating in 1999 with a Bachelor of Arts (Geology).  I then attended the University of Oklahoma, graduating in 2001 with a Master of Science (Environmental Science), and Oklahoma State University, graduating in 2004 with a Master of Science (Environmental Engineering) and in 2007 with a Doctor of Philosophy (Civil Engineering).  Amateur radio even played a role in my graduate research (see my article in the August 2007 issue of QST titled “APRS and High-Altitude Research Balloons.”) 

I have worked for the U.S. Army Corps of Engineers (Tulsa District) since 2007, where I am Chief of the Hydrology and Hydraulics Engineering Section.  Additionally, I am an Instructor in the Department of Mechanical and Aerospace Engineering at Oklahoma State University, where I teach fluid mechanics each semester.  Previously, I have taught courses as an Adjunct Professor in the School of Civil and Environmental Engineering at Oklahoma State University and in the Department of Geosciences at the University of Tulsa.

Look for me on the digital HF modes, where I typically operate either PSK-31, JT-65, or JT-9 on 40-10 meters.  I also enjoy voice for casual contesting and special event stations.  My primary HF radio is an Icom IC-9100.  I purchased this transceiver in April 2017 and have greatly enjoyed using it.  On VHF/UHF, I am active on D-Star (with a SharkRF OpenSpot) and DMR.  I also enjoy using the Tulsa Amateur Radio Club (TARC) Link System and the Kan-Okla Intertie System. 

My primary HF/6M antenna is a Butternut HF-9V that I have owned for more than 20 years.  I have very little space for antennas at my QTH, but I did move and reassemble the vertical antenna in late 2016 and added more coils (it was originally a HF-6V, but I added 12M, 17M, and 160M);  the capacitors were replaced as well.  After running nearly 2,000 feet of radial wire, the antenna works well despite its proximity to my house.  Here's hoping for another 20 years of use!

I also enjoy using my MFJ-1788 magnetic loop, particularly for digital modes.  While it may not look like much, well, looks can be deceiving.  This antenna is a big performer, and is particularly well suited to digital modes since it has a narrow frequency range.  My version can be tuned for any frequency between 15 and 40 meters (30 meters is my favorite band).

A real advantage of the IC-9100 is the ability to operate remotely using the RS-BA1 software package.  I can control the transceiver from my home office, and with the Icom RC-28 remote encoder, I operate digital modes seamlessly even though I am not in my shack.

I am a member of the Amateur Radio Relay League, the PODS 070 Club, the Tulsa Amateur Radio Club, and the Tulsa Repeater Organization.  My personal web page, which contains information about my research activities, professional profile, and other activities, can be found here.  If you are interested in my storm chasing adventures from the past, a couple of my tornado encounters can be found here as well as here.
