My Week in Radio

  • On a vacation cruise, so no radios allowed.
  • Wire was down when I got home, so I got to throw it again. I threw it with a pulley and halyard this time: 42ft up.
  • I built a T2LT flowerpot antenna on PVC pipe and pulled into a tree. It replaced a slim jim built from ladder line.
  • I was looking for that Iran station, but didn’t really hear anything.
  • I got me spinning through other 49M shortwave and looking up the station locations.
  • On the subject of open source: ft2.
    • When you write code (or a book), you have copyright automatically.
    • You choose the license.
    • GPL license says: “I provided the source code for free, so you can modify or build upon it, and when you distribute a derivative work, you need to afford your users the same privilege: distribute your modified source.”
