It seems that there is a bug in telemetry software, perhaps created by the MET reset on each orbit? Each day, recorded files always have the same names: KURSK-944.1 KURSK-944.2 and so on... So I did the following: Every day end, I'm renaming the folder Kursk as kursk1, kursk2,... So I have a folder per day. Next day, when the software is launched, it creates automaticaly a new Kursk folder, that will contains the files from this day, with the same names of past days, but in a new folder.

Hi Roland,
there are several strange things with the KURSK files.
The first one is ARISSatTLM itself - a complete exp file should have a length of 2048 bytes (piece file 1..4 = 504 bytes and piece file 5 = 32 byte) An .exp file generated by ARISSatTLM is 1797 bytes - so the software incorrectly joins the files together. But this is a known bug.
The last "valid" KURSK file was sent on Aug 13 and was created by ARISSat at 22:32:42 ( don't know the timezone but let's say UTC)
Since this date we receive always a KURKS file with this 944 MET timestamp. If you look into this telemetry file you can see an internal timestamp (created at BCD) with Nov 16, 12:47:09 UTC !
If you have a KURSK file with MET = 944 in your directory you will see no new incoming data. This is why your workaround with the new directory works. I assume all your new created directory contain this 944.x files.
So it seems, we will receive no new KURSK telemetry data from the satellite.
I don't know if there is a possibility to reset the experiment by a command from a control station.
