Genosse Funkamateur Roman,

Tnx for the info. The RX is now watching here ( i had to optimise the filters a bit).I have a sked with SV8CS later and he said he will TX soon. Hopefully, if the rain is not to strong, i can join in later.

GL, 73, Stefan

Hi Stefan, LF!

Will someone transmit on LF over the weekend?

Alexander R7NT informed on rus forum 136.su - he started JT9-10 on 136.405 kHz 
using last version  0.9.14.0

Hello Stefan,

internal frequency conversion is on my to do list.
For now I am focussing on the implementation of uploading to PSKreporter, once 
that is done I will target the internal frequency conversion.
Unfortunately I have only limited time to work on SlowJT9 (not retired yet and 
lately a lot of work for UBA).

Rik, LF,

Your latest version seems to work well, even here, with VAC included. No
crashes so far. The software is running in TX mode at JT9-10 since a few
hours, but no PA connected.
Also the slower scrolling spectrogram works well.

The only remaining problem may be the missing internal upconverter,
which, so far, forces all RX stations to leave their standard 'dial'
frequency (136.0 kHz or 474.2 kHz) or forces TX stations to transmit on
a frequency far below the frequencies used for WSPR and JT9-1.

Will someone transmit on LF over the weekend?

73, Stefan

Dear all,

Beta-release v0.9.14.0 of SlowJT9 has been uploaded, see 
http://www.472khz.org/SlowJT9/.

Changes:
-JT9-10 mode added.
- Waterfall speed will adapt to selected JT9 submode.
- Any (reasonable) value can be entered for tone spacing (allowing flexible 
frequency dividing of the modulated signal).
- Lower frequency limit dropped to 200 Hz (was 400 Hz).
- Option to discard the audio frequency limits added (Settings ->  Mode).
In that case the TX boundaries will be 100 - 4980 Hz regardless of the JT9 
submode.
The RX boundaries however will still be limited by the resampling process:
JT9-1: 100 - 4980 Hz
JT9-2: 100 - 2240 Hz
JT9-5: 100 - 840 Hz
JT9-10: 100 - 415 Hz
- Non fatal bug fixed that skipped PTT handling in the first TX cycle after 
'Halt TX' was pressed.

Bug reports, remarks and suggestions are welcome.
