Hi Ed, This signal can be seen/heard on 630m from across the Northern to Southern mid section of the US. I can't vouch for anywhere else because I haven't been anywhere else to verify it. It can be detected day or night which is quite strange, in itself.

I haven't noticed much of a decrease in activity myself on 630m. I see both wspr and FST4 modes being used. I'm generally refering to East of the Mississippi, as I don't usually take notice of the Western US since most of my decodes are in the Eastern area. I occasionally decode some West Coast VE's and just a few other western US stations.

I think propagation in regards to DX has changed the past year or so on 630m. A few years ago I could consistently log the EU on good propagation evenings in the Winter, but I've come up "zero" this fall/winter season so far with EU dx.
