Hello, my name is Mark (W5TSU). I started amateur radio as KD5AMB (tech) on 02/21/2007 and I hold a general class license. (Working on my Extra.:)

I love electronics and Amature Radio. This website, is my way of keeping notes and sharing with others. If you want to ask questions you can email me at w5tsu @ grennan.com.

I’m currently helping with the M17 project (M17Project.org). M17 is a community of open source developers and radio enthusiasts. We’re building understandable systems in support of the hackers and experimenters’ history of ham radio.
