Topband: Topband Phenomenon

[Petr Ourednik]

Hi all,

I have the same experiences from this weekend during the FOC Marathon on
Topband. I heard the same in case of G's and other coastal stations > it did
not happened with sigs from inland stations... the difference was few S units.

Even more I noticed another "SDE" phenomenon this weekend which sounds strange to me.
I made short vid here: https://youtu.be/cV3rzlsZbA4

QSK has been useless at that time, it appeared only on TB (nothing on 80m).
North signals came thru fluttered. US sigs raised up at that time for several S units.
All happened with 300m long Beverages to NA and SA ...no difference.

Anybody knows what happened to me that morning? It disappeared in 1.5hr...
