Dear Osmocom community,
your input is required in order to tune the re-launch of the OsmoDevCall
talk series. One of the complaints before the suspension in Summer this year
was that the "Friday night 8pm CEST" timeslot was not exactly ideal for several
people.
Finding a common denominator might be difficult, given that Osmocom is a dayjob
for some, a hobby for most, and we're of course not all in the same time zone
or even continent.
So let's try to run a couple of polls to figure out:
* What is the best day of the week for OsmoDevCall?
https://bitpoll.de/poll/CEQnaQKEvO/
* What is the best time of day for OsmoDevCall?
https://bitpoll.de/poll/59dgmzOocT/
* What is the best frequency of OsmoDevCall
https://bitpoll.de/poll/8jyuRJB6Hb/
The polls are open until October 21st, 2021. I would appreciate a high turn-out
so we have a good representation across our community to make an educated decision
about the schedule of futur events.
Can't wait to re-start OsmoDevCall!
Regards,
Harald

Hi!
I just wanted to share that jolly has pushed his 'Software Defined Uk0' code
into publicly accessible repositories now.
There still has not yet been any time to document the setup further, but
I'm happy that he decided to share his code at this early stage.
There's two parts:
* the actual SDR Uk0 phy
https://gitea.osmocom.org/retronetworking/uk0
* the jolly/uk0 branch of osmo-cc-misdn-endpoint
https://gitea.osmocom.org/cc/osmo-cc-misdn-endpoint/src/branch/jolly/uk0
If anyone wants to play with it or improve it, I'm sure jolly would be
very happy to hear from you.
Aside from documentation on the hardware setup, etc. there are a number
of software design questions to be investigated/resolved, for example
how to avoid code duplication / fork of the mISDN kernel to userspace
port, as well as the mISDNuser library. Those parts are of generally
useful nature beyond the SDR Uk0 PHY, and the could also be used for
example in the context of what will run on top of the V5 code I've been
working on to support V5 access multiplexers.
Happy hacking,
