KJ4TDM

I got my Technician license in March 2010 after a short time on CB, then upgraded to General in February 2012. You can find me on the digital-mode frequencies on 10, 15, 20 and 40 meters, and I like working packet QSOs through the ISS. When I have time, I work the LEO satellites with a handheld Arrow antenna and a Baofeng UV-5RE+. I'm also a member of the AMSAT Satellite Communicators' Club.

On the tower

All my antennas live on a 70-foot Rohn 25G tower. Thanks to Shane N4XWC, Timmy KJ4TDK and Clint KJ4VVZ for helping put it up — you can watch the time-lapse of us raising it in one day. It's a never-ending job; I'm always changing or adding something.
