As if 10 minutes ago there was a strange signal at 133.360 that was key down for about 2 minutes, then off, then back on.

Yes, fortunately it has stopped, for now.? I have often seen some odd signals on 30 meters, but never that wide or strong.? I know that band is shared, but can't recall with who.?? Hams are limited to 200 watts PEP and bandwidth (indirectly by bitrate I think), so I'm certain it was not ham.? I know the Russians have been using various over-the-horizon radar systems again, but I've never heard them that strong.

Went to 30 meters to listen and found this strong, loud signal going from about 10.132Mhz to above 10.150.? Anyone seen this before or know what it is?? Does anyone else see it?

?

was checking Ft8 frequency on 10.136 mhz and heard/saw this. Anyone know what this is?
