Hi,
there is a digital signal in the mixed mode segment of the NB transponder (10489.650), almost every day, 24h.
Does anybody know what it is and which software can be used for decoding ?
vy 73, Kurt
decoder for unknown signal ?
-
KG-STV (digital SSTV) from (mostly) an italian station.. IDY?
Just discussed in the shoutbox a few hours (<24) ago..
-
Yes KG-STV Application for Windows, usually at 10489.625 +/-.
I confirm. But last week hearded similar signal with more BW, unable to decode.
Regards

FreeDV? > https://www.sigidwiki.com/wiki/FreeDV_COHPSK (2 peaks in the middle of the digital Signal visible)
Both modes are used from time to time on QO100 NBTP

Yes, I can confirm KG-SSTV and also EasyPal.
Both digital picture transmissions ...
Center activity on 625.
I´m one of the transmitting (and receiving) stations ....
Any questions?

Both modes are used from time to time on QO100 NBTP
Are Tests in Free Dv possible ? Are there any restrictions to use this mode ?
Thanks.
free DV explains the "WB" signal exceed limit of KG-STV band.
Now all is explained !

A few days ago i had a successful QSO with an austrian OM.
The DV signal is much smaller (1,2kHz) than the allowed 2,7kHz, so no problem on NBTP.
If you want to do a test then install the SW and let me know.
