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 :-)
