Dear Osmocom community,
as the pandemic continues and physical meetings are out of the question
for the forseeable future, it would be a good idea to have a periodic
virtual online meeting of the interested Osmocom community.
I was thinking of a format where we would serve two major purposes:
1) technical talks about osmocom relevant topics - ideally
current/recent developments
* can be pre-recorded to avoid any problems with technical setup,
streaming, ...
* should ideally have a Q+A session at their initial "airing" during
one OsmoDevCall
2) unstructured solicited social event (USSE)
* random chat in audio (optionally video)
* not recorded, obviously
The recording of the technical presentation should then be permanently
made available (like the presentations of our prior OsmoCon /
OsmoDevCon).
Not every OsmoDevCall would neccessarily need the two parts, but I think
it would be great if we can make that happen. We could also have e.g. a
two-weekly schedule for the USSE and a monthly schedule for the
technical presentation.
We'd need somebody to volunteer to "manage" the "broadcast" side of
this, preferably somebody with at least some prior exposure to online
events (like the c3voc).
I'm using https://osmocom.org/issues/4928 to collect a tentative list
of topics. Feel free to add your ideas there, as well as any comment/
feedback you may have.
Regards,
Harald

Hi,
I´m trying to get my FUNcube Dongle (V1.O NOT the Pro+) to work on
Ubuntu 20.04.1 LTS but it doesn´t work.
On a rasberry pi4 (Raspbian 10) the dongle is working in
gnuradio-companion together with the osmocom-source. So the hardware
seems to work.
On Ubuntu I get following errors:
1. Gnuradio-companion as "osmocom Source" with device string "fcd=0":

When configuring gqrx the dongle is listed. But after every start of

Hi Guys…..
Um im far from an expert at all this, I hardly even know what this device is capable of doing.. but I bought one because they sound very interesting if you know what you doing, what you can tune into etc…
But I have run into some trouble..
I bought a RTL_SDR Receiver R820T2 USB Tuner 100KHz-1 7GHz UV HF… I have a Mac OS running MoJave version10.14.6 (18G103).
I downloaded CubicSDR, it installed perfectly.. the trouble I’m having is the software not picking up my Tuner.. well it does pick it up after a few minutes, but its like its not throwing enough power to keep a stable connection to CubicSDR..
What can I do to fix this? Is there anything at all I can do to fix this pretty easily? Or is it very hard? Or do I have to buy more parts etc??
Can you please let me know so I know if its just a waste of space lol…
Cheers,
Regards
Jarrod
