Unidentified strong signal here in east Tennessee, sending five dits and repeating. At 18:17 UTC it was sending six dits then faded. Recoding on my YouTube channel:

Five clean dits and then silence is an odd one — does it repeat on a fixed cycle, or was it a one-off burst while you were listening? These little ditters are what got me into listening around 6.7-6.8 MHz in the first place; half the fun is that nobody ever quite pins them down.

It sends the five dits, pauses for about two seconds, and sends five dits again with this pattern repeating as shown in the YouTube video. Like it is sending Morse "5 5 5 5 5..." Sometimes it pauses for a bit longer between sets of five dits. There might be a pattern to that, it has faded before I could really determine the overall timing.  It sometimes sends six dits. At one point I heard and saw in the waterfall both five and six dits slightly off frequency from each other at the same time. I have friends in Colorado and Florida who also hear it. Seems to be fairly regular here between 17:00 and 18:00 UTC.  I am hearing it today at 17:30 UTC.
