Hello Rik, LF,
Congrats to the latest version! I'm going to install it now and hope it
will work well here too.
What about the JT9-10 mode? It could be very helpful on 2200m these
days.
My VLF TX was running for 3 days without a single interruption. Now i
stopped it and do QSY to 137 kHz. It means that i can receive again
there and hope to see some messages into the monitor field. Also i plan
to transmit, if all works well.
Looking forward to a QSO.
73, Stefan

Dear all,
I finally found the time to implement JT9-5 and just uploaded v0.9.12.5.
Be ware that this is a ZIP file
that only contains the SlowJT9.exe. In order to use it you need to
install version 0.9.12.4 (if not already done) and replace the
v0.9.14.4 SlowJT9.exe by the one in the ZIP file.
The JT9-5 mode was just briefly
tested but seems to decode fine at -33dB.
All reports on JT9-5 tests are
welcome, as well as any bug report, remark or suggestion.

Dear all,
Beta-release v0.9.12.4 of SlowJT9 has been uploaded, see http://www.472khz.org/SlowJT9/.
Changes:
- A bug fixed that sometimes caused the application to crash at
the end of a transmission.
- Ability to select double or quadruple tone tone spacing
(Settings->Mode)
- Ability to display the own transmission in the RX frequency
window (Settings->Mode).
I got very few bug reports from the previous version (0.9.12.3),
so either SlowJT9 is running quit stable or people are getting tired of
sending me bug reports ;-)
Bug reports, remarks and suggestions are still welcome.

Dear all,
I just uploaded a new beta-release of SlowJT9 (v0.9.12.3).
The reporting to debug.txt is been extended (in particular during
TX).
I also fixed a array bound violation that caused crashes once in a
while.
JT9-5 and JT9-10 modes are temporarily disabled, my first goal is
to have a stable version before tackling new features.
Be aware that due to the baudrate changes there is NO
BACKWARD COMPATIBILITY for JT9-2 and JT9-5 to version prior to 0.9.10.
In other words: JT9-2 and JT9-5 send
with v0.9.11 cannot be decoded with versions v0.9.00 - v0.9.03 and vice
versa.
The JT9-1 mode however is still the same and can be sent /
received with all versions (and is WSJT-X compatible).
The purpose of this version is to determine the stability
of the application.
Therefore all test reports, remarks, suggestions and
opinions are most welcome.
I want to thank everybody who gave feedback, suggestions and bug
reports over the past weeks, this was very much appreciated! In
particular Markus, DF6NM, for his patience in explaining me how to
implement windowed sinc interpollation for the resampling.
Whoever is interested can download the SlowJT9 version
0.9.12.3 installation file at http://472khz.org/SlowJT9/.
For now only a Windows version of SlowJT9 is available. But as the
used IDE has cross platform facilities it should be possible to support
other operating systems as well in the future.
