We have received ORCASAT but have in mind that it is active only over Canada.
New TLE set for ORCASAT, unfortunately due to the limited data is not very accurate:
ORCASAT

The SPORT intended configuration at deploy was 1200 baud for the beacon. The onboard computer commands this in the radio. We have been having hardware resets of both the radio subsystem and the onboard computer since being on orbit. When the radio resets it comes back on line and defaults to 9600 baud. When the computer reboots it commands the radio to 1200 baud.

From https://twitter.com/ViennaHamRadio/status/1611539181280313346 it seems that TJREVERB may transmit at 144.39 MHz. I’ve added the transmitter and scheduled a couple of observations.
Also probably from someone from the team there was an update on the LORIS transmitter baudrate from 19200 to 9600. Let’s see if we are going to get anything.
Finally I was about to identify ORCASat based on SatNOGS Network - Observation 6995051 . However I got a similar signal on different frequency (the one of LORIS), that matches the same object SatNOGS Network - Observation 7004278 . So, I’m now wondering if the signal we recognize as ORCASat is indeed ORCASat or something else (maybe a terrestrial transmission?) and why we got similar signal at LORIS frequency. More observations have been scheduled for both to solve this mystery.

I’m not going to keep scheduling TJREVERB, ORCASat and LORIS.
For TJREVERB we haven’t received anything since its deployment, so probably is DOA. Unless we have a request from the team or any update that proves reception, I don’t think there is any point on continue scheduling.
For LORIS and ORCASat, given that the satellites are transmitting only after command and they don’t have any beacon, I’ll wait feedback from the teams (@loris-ops and @ha6bli ) on the questions asked in Observation 7014595: LORIS (99233) and in Observation 6981462: ORCASat (99232) , as well as specific timestamps that they try to communicate with their satellites in order to schedule Network.
Of course station owners can keep scheduling all the three of them.

In light of the following post, I wonder if it might be possible to schedule some additional network observations for NUTSat (436.850 1200 baud APRS)? Thanks!

Body of the Twitter post:
As I know, NUTSAT is currently in low power status, so the DIGI function has not yet been activated. The control team hopes to obtain more telemetry data from regions outside Taiwan to identify the problem and find out how to resolve it. Thanks for your concern! 73 de BX1AD

@bx1ad can you provide a link on how you can decode the data of NUTSAT?
I’ve quick searched in https://www.tasa.org.tw/inprogress.php?c=20030402&ln=en but I didn’t find anything.

Please share details (a link to a description would be great!).
It looks like I’ve already done a similar decoder - your OBC data is additionally encoded in something like Base64 hexadecimal!?
