GBPPR Vision
    Must See TV    


This is a small video series hosted on YouTube which is aimed toward hobbyists & hackers covering topics related to amateur radio, homebrew electronics, test equipment, computer and telphone network exploration, mad science experiments, and other similar interests.

It's not very good and there are MUCH better videos from other people on YouTube.  I encourage you to support those instead.  If there is enough interest, I'll try to make more videos.

    • Raw video from the July 12, 2014 hamfest in Oak Creek, Wisconsin sponsored by the South Milwaukee Amateur Radio Club.  It started to rain, so I had to kinda hurry through.  It was also difficult to carry the camera and all the crap I bought, so the video is very shaky with lots of images of gravel and grass.  Oh well...
