Thanks for the report!

I’ve updated the related entry in DB, so the transmitter is set to “FSK AX.100 Mode 5” and 19k2 baudrate, if I got this wrong let me know, or ideally suggest a change directly in DB.

By the way, according to space-track.org this is HONGHU 2 satellite, so I’ve changed also the name of the satellite based on this.

2026-09-26 03:57 UTC. Unattended reception of raw telemetry from HONGHU-2.
The signal was demodulated with UZ7HO’s ax100nocrc32 SoundModem using the same trick I had published on “X”.

Congratulations! I didn’t thought of it

Unable to download, it seems only people with a Google account can download the file.

Are there still people without a Google account? Personally, I don’t have a Microsoft account, even though I’m a Windows user.
Sorry for the late reply, but my Internet connection at my summer QTH in Chalkidiki is somewhat slow. Anyway, here it is Upload files for free - 03-53-31_401610418Hz.wav - ufile.io

No Google account needed.

[dl7ndr]

Why not just upload it here?

[PE0SAT]

Thanks.

And yes there are still people that although it makes your internet live more and more difficult still try to stop those companies that sell your privacy.

Is there a way to upload files > 20 MB?

[dl7ndr]

Sorry, you are right! Didn’t know that.

Looking at the 2023-193 cospar id, there is a TY-33 on that launch and here we see TY-30.

These Chinese satellites are always a challenge to identify.

@PE0SAT

kTY-30,

yes , CSP more proper .
