Last night I tried JT65 mode on 15m band. Before I checked on 20m. The 20m band condition was not so good. It was unstable.
However, the 15m was big different compare the 20m. It had many stations signal. Almost signal came from the Europe.
Maybe signal drop point was not mutch. So signal was strong but as same one way situation.
Everyday on 15m is good, but 20m is no good. When it improve the condition on 20m?
