Last night here, on 15m condition was very good and big open.
It was my first time situation on the band. So many DX station decode my WSJT-X that JT-Alart show total 16 stations by one time.
Normally if the band condition was good, but JT-Alart show max 8 or 9 stations.
However, last night show 16 stations.
Therefore I was continue QSO about 2hour more.
Finaly I was contacted total 30 stations on JT65 mode by 1 day. One day 30 QSO, it is my first experience.
I was enjoyed last night.
