I checked eQSL. I found rear case eQSL as follows.
Please show it that signal report column. Before I heard the JT65 mode specification that it can detect signal at -25dB as normal case.
However, this QSL wrote -28dB. Can it detect signal report true?
I usually used WSJT-X software. that software can showed -26dB sometimes. but can not show -28dB.
Is this true or not? I don't understand this matter.
