I was not aware of this satellite, thanks Roger!

For those who use the SatSat iOS app be aware that there are two entries that match the name of this satellite: UVSQSAT and UVSQ-SAT. UVSQ-SAT is the one that you want to use.

I got the information from N1ID, and I think he got the information from the AMSAT mailing list.

Shame its only going to be active as a voice transponder for 2 days

Wow 2 days. The first of the two days is already over.

Hopefully there will be other activations of the FM transponder in the future.

Update

My original data was not correct, apparently the frequencies were transposed.

Sorry about that, I had no way to test it.

Thanks to N1ID for testing and using that satellite, and alerting me to the problem

Perhaps the satellite operators can be lobbied to occasionally activate the voice transponder, perhaps 1 day a week, if they are worried about battery consumption etc

The CPS allows you to specify URL for the satellite KEPS data, if https://www.celestrak.com/NORAD/elements/amateur.txt does not contain the keps, you need to choose a URL that does contain the data.

The orbit data is
https://celestrak.org/NORAD/elements/amateur.txt
CAS-5A (FO-118) 1 54684U 22167C 22360.18489760 .00008108 00000+0 51585-3 0 9994 2 54684 97.5390 134.8861 0014368 204.8277 278.4913 15.08970980 2547

there are no frequencies in the transceiver . ;-(

I guess that frequencies come from some other source ?

I looked on the https://www.amsat.org/keplerian-elements-formats/ specification and I can't see anything here about frequencies.
