Hello Stefan, Spiros,

indeed, I messed up the waterfall display a bit, this will be fixed in the next release.
It can be more or less corrected by 
- setting the offset close to 0 (click close to the bottom of the spectrum display, the red line right of that display should move down)
- setting the gain rather high
But the messed up waterfall display will NOT affect decoding.

Hello Spiros, Rik,

Unfortunately the new slowJT9 version does not work here, probably.

The program does not crash. I can see some noise in the spectrum view.
The audio level is jumping arround 50 dB, quite in the center of the
left slider. The spectrum gain is however almost dark, although the gain
slider is pushed to the maximum. RX frequency is 136.000 kHz + the
typical range. I got good decodes in WSPR-15 from IW4DXW and DL7NN in
WSPR-2 from the same audio source. But there are no slowJT9 decodes yet.

My TX is driven from a different PC than the RX, so i have to run 2
separate instances of slowJT9. Maybe i can decode my own signal ;-)
I will give it a try on 136.390 Hz soon. My antenna will be totally
detuned, so the antenna current will be very low on that frequency.
Maybe the signal makes the path to Rik.

Spiros, if this all does not work here, do we want to try in the normal
JT9-1 mode? I remember you were strong enough. I would then go to
137.390 Hz, later. But first, one run in -10.

73, Stefan
