Hi All,
I have tested JT9 under
Windows 7 (64bit). The result was that FTDI Serial Converter could not open
even if it was recognized by the OS.as COM4
It seems more work will be
needed around the interface between WSJTX and Operatiing systems.

Hi Eddie,
I have a
system down during JT9-30 transmitting under Windows XP(SP3) with 1.46GB of
RAM.

Not so here I am afraid, I was hoping to
run on 500kHz.
1) On 2 very different computers the TX switching of the COM Port Latches the
TX on permanently, TX STOP puts it back into RX mode but only closing the
software unlatches the COM port.
2) Audio out levels are very high, higher than any other Ham software, I will
need an audio attenuator between line out and rig.
3) Program runs under an Admin Account but as a User it crashes after different
lengths of time on each computer.
Any one else having problems.? Computer O/S is XP.

Subject: Re: LF: JT9: A New
Digital Mode for MF and LF
This is
exciting news being a 2-way mode, especially as it is 9-FSK, so doesn't need a
linear PA. With bandwidths as small as 0.4Hz for the long version, no-one will
be complaining about how much bandwidth all this digital stuff takes. Unlike
OPERA, the software will be well documented and open source.
There is a danger that, with too many digital modes now available, the activity
may be spread too thinly, a point Mal raised some time back I believe Somehow
though I suspect JT9 will rapidly become the de-facto digital mode on 472kHz
and 136kHz.
I hope that one of the internet databases - PSK Reporter I guess, or perhaps an
equivalent to WSPRnet - will be able to display JT9 activity as this was one of
the great bonuses with WSPR beaconing.
I may give it a go on 500kHz next week.

Oh, now Joe
has lifted the secret ;-)
He released the mode 2 days ago and a first update yesterday.
Now it really gets complex which mode to choose. WSPR, Opera, JT9...
But as a digital mode for LF i gues JT9-30 is the most promising at all.
