My money is on JS65. There has been a significant upswing in WSJT activity
recently.
I worked a station in Great Britian from CM87, with 40W. Into a G5RV.
At 23:00 California time!!!
You will note two way QSOs with 48 second transmissions starting EXACTLY on the
minute. The CQ and callsign/grid square exchange have multiple tones.
The "roger"s and "73" alterate between two pitches.
