Many thanks to SWLing Post contributor, Ivan Cholakov, who writes:

Thomas, I did not see a story on the blog about the HF atmospheric heating experiments conducted by the Arecibo observatory a couple of weeks ago.

Thomas Cholakov N1SPY made a video about it but I am also sure a bunch of other listeners were able to tune to the super-strong signal on 5125 and 5095 kHz.

Great video, Thomas!

Indeed, I did miss posting this item. The event timing conflicted with my travel schedule in a bad way. Sadly, I only had one opportunity to tune in and I did too late (by just a couple of minutes!) that day.

Did anyone else catch the on-air experiments from Arecibo?
