Hi, Stefan.
The same problems I have here with the waterfall.
I can receive R7NT, who transmit every period.
I am TXing JT9-10 now second period.
If you wish to try JT9-1 no problem, just let me know.

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

Hi to  All.
I am TXing now JT9-10, + 415Hz - 1st period dial USB 136 KHz.
Reports are welcome.
Waiting for Stefan DK7FC for the sked, this evening.
Also Received many times R7NT on 136 KHz JT9-10.
