This is the explanation why your callsign doesn’t appear on the dashboard.
Your SoundModem decoded your own uploads and GetKISS+ uploaded it to SatNOGS.
However, as you figured out by yourself, you were never heard by BOTAN.
This is a disadvantage of GetKISS+. It uploads everything, even non AX.25 packets.
To only upload digipeated packets or those from BOTAN, try my gr_satellites uploader.
The dashboard checks for the so called h bit. If it is set (h bit = 1), then your packet was digipeated and will be displayed. All five of your packets has h bit = 0, so the dashboard won’t show them.
I’ve removed the h bit check to be able to take this screenshot.
Interestingly, you’ve uploaded only transmitted no received packets.
Good luck with your TX problem.
