Dear all,


I just uploaded a now beta-release of SlowJT9 (v0.9.10).

The changes=C2=A0are


-=C2=A0JT9-2 and JT9-5 parameters changed to the original ones. The slightly s= lower baudrates make better advance of the transmission cycle. In theory th= is should improve S/N by 0.46 dB for JT9-2 and 0.74 dB for JT9-5.

In other words: JT9-2 and JT9-5 send with v0.9.10 cannot be decoded = with prior versions (v0.9.00 - v0.9.03) and vice versa.

The=C2=A0JT9-1=C2=A0mode however is still the same and can be sent=C2=A0= / received with all versions (and is WSJT-X compatible).


- JT9-10 mode (10 minute cycle)=C2=A0added,=C2=A0for the fearless.


I=C2=A0briefly=C2=A0tested v0.9.10 for in=C2=A0JT9-2 mode and it seems t= o decode (at least) at the same level as=C2=A0for the previous versions.=C2= =A0But to determine a difference of 0.4dB, more extensive tests are needed.=

The sole purpose of this version is to determine how JT9-2, and = eventually=C2=A0JT9-5, behave=C2=A0in relation to the previous versions, so= we can decide wether SlowJT9 will proceed with the original parameters=C2= =A0(anno 2013)=C2=A0that imply an odd baudrate=C2=A0ratio between the JT9 submodes or my previous parameters, with "round numbe= r" ratios.=C2=A0

Therefore all test reports, remarks, suggestions and opinions=C2= =A0are most welcome.

For the same reason no other changes are=C2=A0applied.


Whoever is interested can download the SlowJT9=C2=A0installation file=C2= =A0at=C2=A0http://472khz.org/SlowJT9/SlowJT9_setup.exe.


For now only a Windows version of=C2=A0SlowJT9=C2=A0is available. But as= the used IDE has cross platform facilities it should be possible to suppor= t other operating systems as well in the future.
