[TowerTalk] Strange behavior

[Pete Smith N4ZR]

This happens all the timeon 10, and I would presume on 15 as well. 
Particularly in low sunspot years, I've heard and worked Europeans on 10 
at 90-95 degrees just before a real band opening.  K3ZO has made quite a 
study of this, so maybe Fred can elaborate.
