Judging from spots on packetcluster, it look like JT65 has been replaced by
FT8 as the weak signal digital mode of choice.

"A beta release of WSJT-X, version 1.8.0-rc1, includes a new FT8 mode,
featuring a faster turnaround, and it's already showing up on the bands.
According to the notes for the candidate release, FT8 offers "sensitivity
down to -20 dB on the AWGN channel," and contacts 4 times faster than JT65
or JT9. An auto-sequencing feature offers the option to respond
automatically to the first decoded reply to your CQ. The beta WSJT-X also
offers a new mode for accurate frequency calibration of your radio, improved
CAT radio control, and enhanced JT65, QRA64, and MSK144 decoder
performance."
