Topband: 160m Band opening phenomena

[Don Kirk]

Hi Dave,

And here in the midwest (Indiana) it was really dead early this morning an
hour or two before EU sunrise.  I spotted DL5AXX who was peaking 6 dB above
my noise floor at most at 0623 UTC, and no other EU stations heard as I
recall, it was just dead.
