Worth a listen...

Sorry if you've just arrived here from the blog of PE4BAS, but his superb recording of 50MHz bursts, which are certainly not aircraft scatter, and possibly not meteor scatter either, is really worth listening to.

So far, I am only hearing these precise type of bursts on long DX paths, in my case, to the US, and in Bas' case, on a path to JA.  G4RRA also find these bursts on longer DX paths, and thinks they are meteor scatter.  Perhaps the longer path simply gives a greater likelihood of such scatter, perhaps even combining to give multi-hop?

I'm not sure how we disentangle one thing from the other, except to see if the effect on DX paths increases during the upcoming Perseids (around August 12), by which time PMSE and Es will be far less common as we reach the end of the summer season.

Bas' poetic description of waves lapping at the antenna is very nice:

Whatever is refelcting John, it could be meteors? At least it sounds like them. Listen to my recording of meteorscatter bursts.

There are always meteors around of course. Though what occured to me is that the reflections became louder and more often just before the "waves" of propagation arrived. At least that's my observation, we need more audio recordings from several stations to verify this. 73, Bas
