@depegasus I’ve set as inactive the 9k6 transmission to avoid any confusion during scheduling. When you are going to transmit on it remember to set it to active again.

CIRBE received and decoded with the following gr_satellites yml file:
We have (already in gr-satellites 5.2.0) a SatYAML file that uses a custom telemetry parser that the team wrote. Have you tried this?

I’ve scheduled observations for the next 48h as we now have the updated celestrak TLE (see a couple of posts above). In total we are going to perform 1351 observations. In more detail:
ION SCV-010: 102
As people have asked me in the past how I schedule such deployments, here are some details:
Scheduling is done manually by using a javascript script in the observations/new page that randomly chooses some of the calculated observations by keeping a ratio.
I try to schedule observations as fair as possible having in mind the SSA analysis we perform and the rest of the points below.
Scheduling depends on the stations capabilities, so for 400-403 band there are less stations so I start with them in order to get the best for that band satellites. If you are a station owner with a UHF antenna at 435-438 MHz consider adding 400-403 MHz into your antenna range as usually such antennas perform fair enough on this range.
On the radio amateur bands I schedule non-IARU coordinated satellites to a maximum of 40 observations per 48h and only for SSA purposes and until they are identified. I use (it is done automatically by the software) only the stations that have in their settings set that they want to help on the SSA by allowing scheduling of such satellites
On the rest of the radio amateur I share the observations as equally as possible with a little bias on the satellites that their team is active in the SatNOGS community by providing info, helping on development and having integrated their satellite in SatNOGS (DB entries, decoders, dashboards etc).
On all the categories above, in order to be more fair on sharing, I’m splitting the calculated passes usually to 2 (sometimes 3) groups. One is for passes over 30 degrees and the other is for passes under 30 degrees.
Depending on the number of the satellites/stations/observations I may omit to schedule passes under 10 or more degrees.
Finally during LEOP I may schedule more high passes on satellites that are not received or stopped transmitting in order to increase the chance to receive them.

UZ7HO BPSK 9600 AX.25 G3RUH soundmodem is working.
The main problem seems to be a CW interference near the signal, which messes up the FLL. Therefore, disabling the FLL seems a must to decode anything in this recording.
I found that the following parameters seem to work best:
gr_satellites INSPIRE-SAT_7.yml --wavfile iq_76800_7418742.wav --iq --samp_rate 76800 --f_offset 1150 --disable_fll --clk_bw 0.1 --costas_bw 200
This will give you between 2 and 6 decoded frames (for some reason the results are not deterministic).

Thank you Daniel for this information,
I was looking at https://gr-satellites.readthedocs.io/ to get some better understanding of --disable_fll but couldn’t find any details.
Lets see how decoding of more recent observation will go.
All the best,

@BroncoSpace what is width and the interval of “Pleiades - Yearling” transmissions?
There are some signals in observations but I’m not sure if it is noise or actual signal from the satellite.
