from DVB-T (I am a complete neophyte at all of this) and so that particular feature of the device won't be of much use to me, but as for the FM, I'm on the Ubuntu/Linux GNU platform, so I'm awaiting on the kindness of strangers to perfect the kernel drivers enough to match the Windows kit performance. But that's okay, because I'm learning a lot in the process :) On Mon, Aug 13, 2012 at 11:44 PM, Adam Nielsen <a.nielsen(a)shikadi.net>wrote: > so it is /designed/ for FM?

[CFP] Free Software Radio DevRoom 2022
by Andrej Rode 23 Dec '21

23 Dec '21

Dear friends and fans of software-defined radio and free/open-source radio topics in general, FOSDEM 2022 (the free and open-source developer's meeting usually in Brussels, Europe but **repeatedly virtual**) will again feature a track on Software Defined Radio and any other radio-related topics in the **Free Software Radio** devroom. Therefore, we invite developers and users from the free software radio community to join us for this track and present your work, ideas and/or demos. Given the current circumstances and the virtual nature of this event in 2022, we are asking the presenters to pre-record the talks, which will then be gathered by us and streamed during the event. Presenters are also asked to be present online during their timeslot for live Q&A. Software Radio is an important tool for educators, tinkerers and industry to implement signal processing and communication algorithms in software while still allowing for easy access to real signals. This allow anyone to access the EM spectrum out of curiosity, for research or for profit. At FOSDEM we want to foster collaboration and exchange of ideas between different projects in the field of SDR. We hope to network all these projects, and improve collaboration, bring new ideas forward and get more people involved. The track's website resides at the link below. The final schedule will be available through Pentabarf and the official FOSDEM website. Notice that the reference time will be Brussels local time (CET). https://fosdem.org/2022/schedule/track/free_software_radio/ Additional Information will be also available at: https://wiki.gnuradio.org/index.php/FOSDEM_2022 ** Submit your presentations To suggest a talk, go to https://penta.fosdem.org/submission/FOSDEM22 and follow the instructions (you need an account, but can use your account from last year if you have one. Please do NOT create a new account if you already have one). You need to create an 'Event'; make sure it's in the Free Software Radio track! Your submission should have the following information: * Your contact Email * A descriptive title and subtitle of your talk * A short abstract * Links related to the project * [Optional] A longer description of the content of your talk. Lengths aren't fixed, but give a realistic estimate, and please don't exceed 30 minutes unless you have something special planned (in that case, contact one of us). We will typically go for 30-minute slots -- shorter talks, unless they're really short, usually tend to screw up the schedule too much. Please take into account some live Q&A at the end of your presentation, going for 25 minutes presentation plus 5 minutes for Q&A will provide a more lively conference experience for everyone. You aren't limited to slide presentations, of course. Be creative. However, FOSDEM is an free software conference, therefore we ask you to stay clear of marketing presentations and present something relevant to free/open software. We like nitty-gritty technical stuff. Topics discussed in this devroom include (but are not limited to): * SDR Frameworks + Tools * Cellular/telecoms software * Free/Open SDR hardware * Wireless security * Random fun wireless hacks * SDR in education * Satellite/spacecraft communication * Ham radio related topics ** Important Dates * Submission deadline: 26 December 2021 * Announcement of selected talks: 31 December 2021 * (preliminary) Pre-recorded presentation submission deadline: 23 January 2022 * Conference dates 5 & 6 February 2022 online * Free software radio devroom date: Sunday 6 February 2022 online In the last years we were always full to the brim with presentations, so if you want to present, please make sure to submit your abstracts soon! (It might be possible to get our allotted time extended to Saturday - given enough volunteers and high quality presentations to cover two days, but that's only an option as last resort) ** Following steps for accepted talks When your talk is accepted, you will be contacted by a deputy who will help you with the pre-recording of your talk. Together you will make sure that the content has the required quality and is stream-ready. When complete, the recording will be located into the streaming system, and Bob's your uncle. Don't forget that you **must** be available during the allocated timeslot of your talk for live Q&A. ** Steering Committee The track committee consists of: * Phil Balister - "Crofton" * Derek Kozel - "dkozel" * Andrej Rode - "noc0lour" * Martin Braun - "mbr0wn" Hope to hear from you soon! And please forward this announcement. Cheers Andrej

Have you tried deleting gr-osmosdr's build directory and starting from scratch (after remvoing gr-fcdproplus package)? Alternatively you can delete only the CMakeCache file. What is the exact problem that you have right now? Provide the full cmake and make output.

[PATCH] fix osmocom_fft for current main-3.9 gnuradio
by Stefan `Sec` Zehl 16 Oct '21

16 Oct '21

Hi, The commit 86b5fb30182c69ec38490346a4269d1ffce9ffb4 in gnuradio broke osmocom_fft due to removing/renaming the pyqwidget wrapper.

[PATCH] rudimentary sigmf support for recordings
by Stefan `Sec` Zehl 10 Oct '21

10 Oct '21

Hi, This is a starter patch to produce a .sigmf-meta file for each recording. It contains the minimum useful info that is usually coded into the filename. I'm not sure if anyone thinks this is worthwhile. There is a lot more that could be recorded in the .sigmf-meta file like e.g. current gain values, current bandwidth or antenna settings (if available), but i wanted to see if there is any interest for this at all. It would maybe also nice to add the actual sdr device name that was used, but as far as I can see there is no way in python to query which device/driver is used by a specific osmosdr.source()?
