I have tried the following:

$ gr_satellites AMGU-1 --audio default --samp 48e3

and I got an error message:

It seems that https://github.com/daniestevez/beesat-sdr/tree/maint-3.8 is missing

appear to be other missing dependencies.  When trying to reproduce this
on sid after installing gr-satellites, I get this error:

$ gr_satellites AMGU-1 --audio default --samp 48e3
Traceback (most recent call last):
  File "/usr/bin/gr_satellites", line 15, in <module>

Re: tony mancill

It would also be interesting to know how many sats/submodules need
some missing python module so we know if the package is
totally/somewhat/slightly unusable without it.

Christoph (who still hasn't found the time to get into LEOs)

According to

$gr_satellites --list_satellites |grep -i mobitex

there are 13 satellites that need this module.

From them, AMGU-1, BEESAT-9, D-STAR ONE, D-STAR SPARROW, DEKART, JAISAT-1,
SOKRAT (total 7) are currently active.

The main problem is that the current status of gr-tnc_nx

https://github.com/daniestevez/beesat-sdr/tree/maint-3.8

works only on gnuradio 3.8, which is only available in Bullseye

For gnuradio 3.9 and 3.10 there is an open issue on gr-satellites github page:

https://github.com/daniestevez/gr-satellites/issues/238

I do not know how this can be resolved as there should be a new package
introduced directly to stable.

Re: Apostolos Kefalas

Thanks!

Hmm, that doesn't look good.

We should focus first on getting this fixed in unstable, that will
already be hard enough.

Dear maintainer,

I've prepared an NMU for gr-satellites (versioned as 5.8.0-2.1) and
uploaded it to DELAYED/2. Please feel free to tell me if I should
cancel it.
