I heard 3B9C yesterday Monday evening UTC here in west Central Florida. He was
559 on my tee vertical and 579 on my low doublet. He peaked here at his local
sunrise.
The opening into our region from 3B9C on Sunday and Monday evenings UTC
occurred as I predicted a few days ago because of a winter storm system near 30
deg. north lat. and 60 deg. west long. that ruptured the E valley-F l layer
duct mechanism on a bearing into Florida. You can see the winter storm via a
satellite image at this link: http://www.kn4lf.com/sub/20040323WV.jpg . This is
the system that created the high QRN level on 160 a couple of nights ago.
If the storm system is strong enough to show up at 500 mb then it can create an
upwardly propagating Internal Buoyancy/Gravity Wave capable of rupturing the E
valley-F l layer duct mechanism.
