The article mentions that the burst were discovered by the radio telescope at Arecibo. I was there a few years ago, and I recommend the trip to anyone going to PR. It takes a bit winding through West Virginia like back roads up and down ridges and through small hollows to get there, but it is worth it. The scale of the telescope is so breathtakingly immense that it is not properly conveyed in film or on television. And even though it is no longer on the cutting edge of radio astronomy, it just feels as if it would be the first place to make contact.
It also sounds like a really fun place to have a drone and some transmitting equipment. :) Imagine the fun one could have with a few millisecond bursts.
