I have released an updated version of the Pacsat Ground station which now
does a better job displaying the decoded beacons from Mir-Sat-1. It also
fixes several small bugs in the conversions and in decodes. This also
fixes a bug that impacts FalconSat-3 file downloads in some cases.
Download it from here: https://www.g0kla.com/pacsat/index.php
Let me know any issues or problems you see. Please continue to download
telemetry for Mir-Sat-1 during their commissioning period. All telemetry
is sent to SatNogs assuming you check "Send Server Telemetry" on the File >
You can see that your Mir-Sat-1 telemetry was uploaded here:

I guess APRS-to-Voice is a new mode and people are just not used
to using it. Its really easy as described on the PSAT2 page:
For some reason the URL for downloading keps in nasabare format from AMSAT
website is failing using the update Keps function in SatPC32. Did I miss
something and has the address been changed or is the site down?
Mir-Sat-1 will be deployed from the ISS Tuesday at 10.55 UTC by JAXA. This
satellite will support an AX25 digipeter and images broadcast with the
pacsat protocol. The images will be taken by its camera and stored in the
onboard file system. Amateur stations will be able to request the
directory of files and request the broadcast of images using a suitable
ground station. Many thanks to Jean Marc and the amateurs on Mauritius for
collaborating and getting Amateur Radio included on this mission.
I have updated the Pacsat ground station to support Mir-Sat-1. See my post
here: https://www.g0kla.com/workbench/2021-06-18.php. If you use a GNU
Radio tool chain then Dani has updated gr-satellites to support Mir-Sat-1.
SatNogs is adding Mir-Sat-1 to its decoders and will also store the
received telemetry. If you come up with your own decoder then please
forward to SatNogs.
Use the ISS Keps initially to track it. There is an award for the first
Feel free to ask any questions.

I tried to access the FoxTelem Leaderboard and get this error message:
Apache/2.4.41 (Ubuntu) Server at www.amsat.org Port 80
Does anybody know what has happened??

I was tuning around on 70cm this morning looking for satellites and found a
signal on 437.025MHz sending callsign OM9XPA plus a short burst of digital
signal. Time was around 2021-06-1230utc.
I thought it might be GRBAlpha but that one was not in range at the time.
Can't put my finger on which one it might be.

Is anyone out there successfully using an RTL-SDR with SDR#, a virtual cable, and MMSSTV to receive the pictures from ISS? If so, can you please share your settings with me or point me to a tutorial or something. I can see the signal coming in strong on SDR# and I can see that it's not static noise on MMSSTV, but it's not a coherent photo. I'm getting offset lines of color. For some reason, MMSSTV isn't getting the sync signals (that's a guess on my part). What am I missing?
