"I was on the radio at 1940z. TI3/W7RI popped up 59++ on 50.110 MHz
and in my log at 1941z. Scott, TI3/W7RI worked many stations over
the next 25 minutes. Other TI stations active included TI5XP and
WA8NJR/TI5. The TI stations worked W8, W9 and W0 along with the Gulf
Coast states. This was one hop F2. By 2005z the TI - Midwest opening
was over. A brief but intense opening. Stations further south heard
the OA4TT/b for another hour or so."
Thanks, Jon!
