Dave,
Thanks also. Despite the overhead pass over FN41, the SNR seemed much less than observed before. No frames detected. Might not have helped that another bird was up band at the same time. Nevertheless, given the high pass left wondering if somehow the down-link power was reduced as well? Very curious to see how others make out this round.
Cheers,
Bob

I’m sure it didn’t help Bob’s capture to have a very loud FM repeater nearby.
But, after replaying his I/Q file & recording the audio. GNU Radio was able to spit out some hex decodes.
The il2p_parser.py script found proper frames in his decoded bytes and that allowed SSDV to display a few JPG frames!
… but that’s not the end of the story. Even though we only had ONE capture file to work with (I got zero decodes), I ran Bob’s capture frames through ssdv-merge.py and apparently that scans the ENTIRE file for valid frames (better than SSDV does by itself, apparently). I say that because sending the output from ssdv-merge.py to the SSDV utility produced a more complete image!
… moral of the story is that when I DO get future captures w/ some number of valid decodes, you can bet I’m going to let the ssdv-merge.py script search the file before I send anything to SSDV!
Awesome job Scott! TKS!! Bob
Thanks for scheduling the pass over Japan, but I could get CW only at 2026-01-18 05:55~.
new image.. wow. just browse on satnogs obs
just feeding the script with continues audio from this obs and this obs. the last one is very good station.
superb..
where is this photo taken? pacific ocean?

This was taken just off the mid-Atlantic coast of the US. Hopefully, Silver Spring Md (the ‘Silver’ in SilverSat) is in there somewhere

10 el. Yagi hand antenna + RTL SDR
I’m getting better at manually receiving the signal 
KO95. Moscow region. 18:27-18:31 UTC. Yagi 7el.+RTL SDR V4 This timе I tried to sync the signal’s polarity change - every 5-6 packets signal went weaker than restores, got 174 packets (vs 147 on friday) but more missing places. Next time I will try a helical antenna.

TU.. I was using an old version of the ssdv version that did not include the -l for packet length. With this one in your files.zip it worked 
@bali Just found this Observation on BEEGND-4 and got the same picture from it:
Very nifty script setup. Thank you very much for sharing this with us. I streamed the audio directly from the browser into direwolf by not using pavucontrol, but by connecting them with qpwgraph directly.
Unfortunately I got known of this event only, by your scheduled observation at BEEGND-4. Now I will follow this thread more closely. To everyone: Feel free to schedule BEEGND-4, if there is to happen anything cool related to ssdv again.
WOW greatz. thank you for your sharing page.
my idea maybe you can edit the silver.py and look at line 34:
and change ssdv with ssdv.exe . maybe you can put the ssdv.exe in same directory, or put on C:\WINDOWS folder or similiar?
this will convert the bin to jpeg automatically, no need to do it manually.
wow. nice app, with uix like gnu-radio style. like a pro. 
i’m trying and learn it. thank you
Good news - we successfully tweeted from the satellite tonight. Bad news, we ran out of time on the pass before sending the next set of SSDV commands. It may be mid-week before we get more scheduled.
