Today the day that Hams around the world get to say "Hi" to the Juno space probe. As it passes by the Earth it will be receiving a very slow coordinated Morse code message in the 10 meter Amateur band.
Since I was at work, I was not able to participate, but I did get a QRSS grabber going on the computer that is connected to my HF radio and captured some others sending the word "HI" using 30 second long dits.
