The 84th installment of your most favoritest podcast is now in the wild. As you may have noticed, we make a lot of assumptions about our listeners on this show; for example: You all love us. We have a good show in store for you today, including antennas made from electric fencing, a question about whether GPL software can be profitable, and most importantly a look at software defined radio and the GNU Radio project. Towards the end we address some feedback, solve a technical problem in Italian and try to stage an intervention for one of our more peculiar fans. ALL THIS WEEK on Linux in the Ham Shack!
