Very strong downlink from STECCO on 435.800 1533utc
-Scott, K4KDR
DIY-1 is sending RTTY 100 BD 7N2 SHIFT 450
SATGNOS stations are receiving in wrong CW mode, please correct to USB mode
for properly decodification.
The transmitter is already created but not used as we don’t have a special flowgraph(gnuradio script) for USB mode, this is why we currently use the CW one. If we use the USB transmitter, SatNOGS stations will run a generic FM flowgraph.
Thanks for the info!
ChallengeOne first satellite of Tunisia has been received and for now it fits the TBA TLE set of OBJECT AA(47956).
Current status and fits of spacetrack TLE sets (still several TBA: TO BE ASSIGNED and missing ones), there several changes from the previous fits, as the objects are not assigned is expected to be swapped (with bold the chosen to follow in DB and Network):

No identification as we expect TBA TLE sets to be assigned and also more TLE sets, you can notice that some satellites fit on the same object. Some of the satellites fit also objects with NORAD ID 88810 and 88812 that may be some of the missing TLE sets.
EDIT: I forgot to thank @cgbsat that confirmed independently with strf observations the status and some of the fits above and found out about the 888XX TLE sets.
BCCSAT-1 has just been received: https://network.satnogs.org/observations/3836112/
Interesting how the CW is transmitted in relation with the GMSK signal.
Currently it fits better OBJECT N(47944), as the UNISAT-7.
The CW appears to be performed on whatever tone the GMSK packet finished up on…
Some changes on TLE sets we follow after @PE0SAT strf analysis:
For GRBAPLHA we now follow OBJECT G(47938)
For KSU-CUBESAT we now follow OBJECT Y(47954)

I saw from SatNOGS observations that BCCSAT, that was launched with FEES satelite, is on 22R and well tracked, while FEES are still on 22N which is quite far. Can TLE of FEES be changed from object 22N to object 22Q or 22R?
Best Regards
Milo YT2CQ
I’ve updated to OBJECT R, but have in mind that it will not make any significant difference. The best way to see that is by using a software, like Gpredict, that shows the visibility from the ground. In this case as you can see in the image bellow whichever ground station tracks the one OBJECT will also track the other too as the actual difference of the rize/set time between the two OBJECT is some seconds:
Latest update using ikhnos, which by the way has a new version. All the TLE sets are assigned to objects, however there are still missing ones:

We are missing several TLE sets, except from the current number of the sets which is less than the number of deployed satellites, there are several cases that we don’t have good fits. For example we miss at least two objects between OBJECT F and OBJECT M that will fit DIY-1 and SMOG-1.
Also in many cases we go back and forth on rejecting/adding objects, this is one more result of missing TLE sets, as current objects change their orbit parameters and fit(or not) the observations we have for each satellite.
Unfortunately we haven’t received again STECCO, however it seems that there is at least one unknown satellite that transmits at 435.805 and fits the TLE sets of this deployment. In some cases the signal looks almost the same with BCCSAT-1 and some other like CW or a simple carrier. We have created a satellite in DB with temporary NORAD ID 99719 to watch this satellite. Another possible satellite could be at 435.795 but we still need more observations to confirm it.
Some of the observation where the unknown satellite is visible:
https://network.satnogs.org/observations/3858176/
https://network.satnogs.org/observations/3858223/
https://network.satnogs.org/observations/3847755/
https://network.satnogs.org/observations/3856738/
https://network.satnogs.org/observations/3845478/
https://network.satnogs.org/observations/3847320/
Do you also use ikhnos
against the analyst 88XXX objects?
To be honest, I avoid to use these OBJECTS as are not officially(from spacetrack) from this launch.
Is there any change from this status?
One of the unknown satellites at 435.800 MHz is BCCSAT-1 as the signal contains its callsign, from observation SatNOGS Network - Observation 3858224 checking the two signals that are visible in the audio waveform we have:
EDIT: Here are two other signals around 435.800 MHz:
One at ~435.805 MHz which is just a carrier:
https://network.satnogs.org/observations/3861511/
One at ~435.795 MHz which looks like dots:
https://network.satnogs.org/observations/3861451/
Wondering if any of these two belongs to STECCO transmitter or maybe to BCCSAT-1 too.
For completeness, we need to have in mind that we still missing reception of FEES and the two CANYVAL-C satellites.
EDIT2:
Signal at 435.795 MHz could be also BCCSAT-1, as in this observation SatNOGS Network - Observation 3861494 it is visible at this frequency.
FEES LoRa beacon are recieved on tinyGS network.
Observation follow OBJECT R(47947). Maybe next candidate is OBJECT J(47940).
