After some discussion in https://osmocom.org/issues/4928 and on IRC,
I've now put together a wiki page at
https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCall

Right now there's still a chance to influence the scheduling
(current proposal is Fridays 8pm to 10pm CET).  If you would want
to participate but think this is a really bad time, please speak up
now :)

Once it is clear where we will host the call, I'd be announcing the
first event, which could then be as early as Februray 26th.

I'll keep you posted.

Regards,
	Harald

	https://meeting4.franken.de/b/har-xbc-bsx-wvs

This first meeting will have the following schedule:

20:00 meet + greet
20:15 presentation about Cell Broadcast and OsmoCBC
20:45 USSE: unstructured supplementary social event [*]
22:00 close of call

Attendance is free of charge and open to anyone with an interest

[*] this is how we started to call the "unstructured" part of osmocom
developer conferences in the past, basically where anyone can talk about
anything, no formal schedule or structure.

Subject: Support on a RTL_SDR Receiver R820T2 USB Tuner 100KHz-1 7GHz UV HF

Hi Jarrod - it could be the cable.

If you have USB-C, try using an adapter to micro USB. Try using a USB 
hub with a power supply. Make sure the power is plugged into the 
compuier. Disconnect all the other non-essential USB devices.

Check the load on the computer when you have trouble - and use lsusb - 
see if the device connection to the computer is acting funny.

I believe you can use "brew lsusb" to install it you don't have it 
installed.

If you can uninstall the RTL dongle, try uninstalling it and then 
re-installing it.

Subject: FUNcube Dongle V1.0 not working with osmocom Source

Hi Dennis - type

 ??? apt list --installed | grep boost-all

and make sure it's installed.

But my first guess would be you're running the wrong version of 
gr-osmosdr for gnuradio 3.8.1.0.

I'm running gnuradio-3.8.2 and gr-osmosdr version 0.2.3 but I use github 
to update my software so I really don't know what the minimum version of 
gr-osmosdr is required for gnuradio-3.8.1.

Maybe someone on this list might know.
