the result is this lot.  The file specified is a valid, and correctly

I want  to use the command line driven JT9.EXE prog to decode some
JT9-Fast signals.
While the -Help option shows which tags to include for modes and submodes,
I don't see any indication of what to include to decode teh -fast modes.

I also assume the  " -b " submode tag applies to whichever mode is
selected.

So I see the full command, for JT9G-Fast on 10 seconds cycle time, 700Hz,
300Hz DF  looking something like this:

JT9 -9 -b G -p 10 -f 700 -F 300 [wav file name]

OR does the fact its specifying a short cycle time automatically signal to
use -fast mode decoding?
