Thanks Jay,
Yes it would be interesting to do the same test with JT9-30. This mode
must be the most interesting for weaker LF stn to plan to make a first
TA decode for example. So far "we" concentrated on < JT9-2, with some
exceptions. UA0SNV decoded me in JT9-10 over nearly 6000 km. But this
was with some of the older versions. Probably the newer modes perform
significantly better. So maybe its worth to do some first slower tests.
BTW somehow the LF TA path seems to be problematic in the last weeks or
months (relative to the time of the year). I remember it was much easier
to leave traces like last night in August or September, even more
regularly. Can you confirm this observation? Remember your copy in
normal WSPR on 137 kHz in August (if i remember correctly).
Another thing that might be interesting for Laurence: I got the
information from Yas/JA8SCD that JP1ODJ/JD1 is running a temporary LG
grabber at http://www16.ocn.ne.jp/~macoco/JP1ODJ_JD1_grabber.html
This is certainly an interesting QTH and Laurence may make that distance.
I will try it as well from here, however the solar activity reduces my
chances drastically... Anyway, i'll run the TX during the entire
possible DL-JA opening. Who knows :-)

I'll continue to run more DFCW than digimodes on LF in the next time.
Looks more promising and less critical.
FYI ... ran an interesting test a couple weeks back on 137 kHz during
one of your OP32 runs. Had Argo operating in QRSS30 simultaneously
with Opera. At the time you were decoding well around EU and in TF so
your setup must have been working okay. Even though there were vivid
white traces on Argo for nearly the entire period there was no OP32
copy. You could have been easily decoded with QRSS20 and perhaps even
QRSS10.
I'll see if I can find the capture and send it along.
