Hello various Osmocom mailing lists,
the official Osmocom binary packages will not be built anymore for the
following distributions starting at 2024-02:
* Raspberry Pi OS 64-bit (use Debian_12 etc. instead)
* Ubuntu 23.04 (Ubuntu 23.10 and LTS 20.04/22.04 feeds are available)
* openSUSE 15.4 (openSUSE Tumbleweed feed is available)
* Debian Testing (Debian Unstable and 12-10 feeds are available)
For Raspberry Pi OS 64-bit users, make sure to adjust your
/etc/apt/sources.list.d as described here to switch to a Debian
aarch64 feed:
https://osmocom.org/projects/cellular-infrastructure/wiki/Latest_Builds
See the new linux distributions article for information on how long we
plan to keep building packages for each distribution:
https://osmocom.org/projects/cellular-infrastructure/wiki/Linux_distributio…
Let me know if you have questions.
Best regards,
Oliver

Hello,
Is there any chance the following patch could be reviewed and/or merged
into upstream gr-osmosdr? It allow multiple Airspy devices to be used
(which is sadly not possible without the patch). The patch is already used
in the downstream gr-osmosdr package in Fedora for last two years and seems
to work without issues.

Thanks!

Hello,
Please, consider doing a new tag/release of rtl-sdr. The last tagged
version is from 2018 and there were many changes since then including the
recently added RTL-SDR V4 dongle support.
Thanks!

After seeing the osmo-fl2k[1] project, I've bought a USB VGA dongle,
hoping it would contain a FL2000.
The model I've bought looks identical (from the outside) to the black
one on the picture. Unfortunately it contains a different chip: a
Macrosilicon MS9120.
There is not a lot of information about this chip, the manufacturer does
not even publish a datasheet (I've sent them an email to ask for one,
but don't have high hopes).
What I've found so far is:
- someone's reverse-engineering attempt of the android driver[2]
- a bit of python code to read & write the chip's memory[3]
The second thing is for a different chip by the same manufacturer, but
it seems to work with my device as well.
So, I was wondering if anyone here has already attempted to re-purpose
this chip as a transmitter :)
cheers,

In future blog v4 production batches (out in several months time), it
will be possible to turn off the upconverter when tuned outside of the
HF bands. Please add the code to control the GPIOs to turn off the
upconverter when it is not in use.

Just realized my patch attachments are getting scrubbed by the list.
Hopefully this plain text paste works.
