[TowerTalk] Fwd: Fwd: Strange behavior

[Hans Hammarquist]

 Well, maybe Herb, KV4FZ is on a better, easier to explain track. There might be something with your beam that skewed the radiation pattern although that to happened on three different beams on three different towers sound not that plausible. 

An other explanation could be that a new structure has been erected and that change how the EU radiation reaches your station.

A permanent change due to atmospheric conditions doesn't sound right.
