I haven't looked at your 136 kHz list in a while ... it was quite a trip down 'memory lane'! Your work on the list is much appreciated.

Stefan,

2012-11-29 W1VD rxed DK7FC in JT9-10 - best QRB=6105km in JT9

A pitty that then 'slower' JT9 versions have been abandoned.
I found in particular JT9-2 (2 minute sequences) very useful on 472 kHz. A QSO took about 10 minutes and these was a +/- 3dB advantage over JT9-1.

I think that W1VD has detected my signal some years ago. But that was
not JT9-1. There have been older versions of JT9, allowing to use longer
time periods, up to 30 minutes i think! That was better for LF!
I am not so sure about the detection by W1VD. Maybe Jay want's to comment...
