Midwestern rivers have a serious problem with an invasive species of carp that the USGS was trying to track using radio tags (yep, on the fish). But they needed some radio expertise to advance the project to receive the signals using drones rather than people with yagi's on boats. Dave Witten KDOEAG got involved through a request for help at his local radio club.
This talk follows the progress of the project, which rapidly grew to include multiple agencies (including NASA) and experts... and Dave. It's not ham radio, but it is an interesting exploration of radio technology where you might not expect it.
Radio Rating: C+. Dave has lots of pictures of the devices and locations, and some charts and graphs. You'll miss that detail in the audio-only presentation, but you'll get the gist of the project. Watch the video here if you're more intrigued.
