HI Joe, Tobias, LF
That's great, it brings back some logic into the observed symptoms.
Thank goodness the files I have been flooding Joe with have proved
useful, I was beginning to feel I was a complete pain.
The next version could prove quite exciting.

Hi Eddie, Tobias, and all,
I've solved the riddle of Eddie's local JT9-2 transmissions that
failed to decode.
The problem is, as originally suspected, the result of small frequency
drifts -- in this case acting together with the Gray-coding applied to
the data.
I will work on a solution this week, including an appropriate
algorithm for measuring and removing small amounts of frequency drift
as part of the decoding process.
In the meantime, if you're experiencing this problem it's best to
stick with JT9-1 because that sub-mode has the largest tone spacing.
