iPhone app helps you study for your technician class amateur radio exam
Here’s a graph showing the number of unique pirate logging threads on the HFUnderground.com
Each thread represents a different shortwave pirate radio broadcast. The red bars on the right are the number of broadcasts during the shutdown per day. I’ve also drawn in green the average number of broadcasts per day during the month before the shutdown (6.9 per day) as well as during the shutdown (12.2). As you can see, activity is up 77%. This past weekend was extremely active, setting records.
