Hello Paul,

decoder.txt seems OK.

I am sorry if I gave the impression that I thought you were complaining.
Certainly not, all reports on crashes are abnormal behaviour are welcome.
But these rare crashes are very difficult to trance down.
As you stated, for now I will focus on testing and improving SlowJT9.
At a later stage I will try to intercept possible crashes.

Thanks for your help!

Hello Rik,

v0.9.02 installed and monitoring 630m JT9-2 here.

Yes of course. The drift I measured was the actual RF drift of the
signal, measured visually with a high resolution waterfall external
to SlowJT9. The actual drift passed to the decoder would be double
the amount I reported.

Contents of the file:

0359  18  -15   0.3   2188.   0   CQ WB4JWM EM83         JT9

I was not complaining! It ran all night the previous night on JT9-1
and for at least 8 hours last night on JT9-2 prior to the crash. I
don't think it is important to put too much work into tracking down
the reason for a few crashes right now. Better to continue testing
and see if it will be worth continuing the project.

Thank you again for your work! I look forward to more testing and I
 hope SlowJT9 can help with trans-Atlantic QSOs on both 630m and
2200m. As I have said several times before, we are in need of some
help on 2200m. JT9-1 requires quite strong signals and there are few
or no alternatives aside from DFCW/QRSS.
