For compactness, the burn image is overlaid with the time date and freq from WSJTX itself. Yagi is typically at 210 degrees as it is during MSK operations to work South (eg VK1,2,3,7).
Seeing that it is a new year I think it is time for me to find out.
I periodically see similar burns, always angled but can be either forward or backward, varying intensities and periods, always early in he morning before any local transmit activity starts (ie 5AM).
Anybody have any ideas ??
Absolutely no idea - have never seen the effect.
