Re: [FOSDEM] contacts for organisational issues
Daniel, The ham-radio info booth of 2015 was the result of the devroom gnuradio/software defined radio of 2014 where we had a number of people saying "concidering the audience for this devroom, why not try to promote ham-radio a little bit while we are there". So that is why we where in the building where that devroom was held. But, of course, as ham-radio is all about communication, signal-processing and with some homebrew electronics thrown in, you could probably link it to multiple devrooms at FOSDEM. But feel free to make a little bit of publicity for our infobooth / demonstrations in your corner of FOSDEM :-) Cheerio! Kr. Bonne.

Hi all,
The Belgian Amateur radio organisation (UBA) had a small infobooth at FOSDEM 2015 promoting ham-radio. For 2016, we like to expand this with some practicle demos and a permanent station.
Concidering FOSDEM is an event with many thousands of visitors, there might be some practicle and safety issues we would like to discuss. Who in the FOSDEM organisation and/or the ULB can we contact for this?
Hi Kristoff,
There has traditionally been a real-time lounge for real-time communications technologies (VoIP, webcam, chat, etc)
As both a developer of real-time technologies and a radio amateur myself I feel there could be some value in having some of these things in proximity to each other. I'm not sure if there is any formal mailing list for co-ordinating the real-time lounge, there are usually some private emails about this between a few of the developers from the relevant projects.
I realize this doesn't answer all of your question though - hopefully one of the FOSDEM team will get back to you about the issues you raise.
Regards,
Daniel

If I understand correctly, the FOSDEM team want to put an emphasis on development (the D is FOSDEM) and it is good for any stand or devroom proposal to relate to this. Personally, I feel that amateur radio is a development activity because you basically have to pass an engineering exam in order to become licensed. As you correctly point out, in modern radio, development spans hardware and software. You will want to emphasize the software development aspects in your proposal.

Given the nature of communication technology, it may well be relevant to have more than one presence so people can communicate between them. There has also been some discussion about creating a URI scheme for callsigns http://danielpocock.com/a-uri-prefix-for-radio-callsigns and it would be interesting to see that work with SIP or XMPP over amateur bands.

Actually, the FOSDEM team are not realy involved in this. They are just the nice people who provide us with a space for our booth and allow us to promote ham-radio :-) The infobooth of FOSDEM 2015 came from a discussion in the mailing-list of gnuradio where we noticed that there where a number of hams on the list. In FOSDEM 2014, we had a small get-together and one of the things that emerged to many hams nowdays are just "operator" and to few people actually developing things. For FOSDEM 2015, there was somebody who had a spot for a infobooth in the building where the SDR devroom was held who proposed to use part of his space to promote ham-radio. With agreement of the FOSDEM staff, we used that place. But, actually, when one of the speakers of a 2015 talk in the SDR devroom asked the audience how many had already heared about ham-radio, it turned out that almost half of the audience where licensed hams! So it looks like there may be more people involved in software development that are also ham-radio operators then we think. :-)

As you correctly point out, in modern radio, development spans hardware and software. You will want to emphasize the software development aspects in your proposal. My point has always been to show that ham-radio is not just some old guys talking on the radio of a old HF set or doing morse-code. Nowdays, it is now a hobby that is connections to a lot of other hobbies.
In fact, I have already given a talk on "digital voice over radio" (dealing with how voice is encoded, with how to deal with errors in real-time communications, ....) during the software-freedom day in HSB (hackerspace Brussels); so to an audience of techical savy (but not necessairy radio-minded) people. Our local radio-club in Ostend Belgium has had a cooperation with the local astronomy club on meteor-detection via reflection of radio-signals and n two weeks, we will be giving a small info-session on ham-radio during a "star-party" (astronomy observation events) near Iepers. On the other side, I also give a small course on programming and arduino in our radio-club. One of the things I show is that techniques used in one hobby are also used in other fields. One example: it turns out that the techniques used in digital key-board-to-keyboard communication (like olivia, JT65, ...) and WSPR ("weak signal propogation") to extracte a radio-signal up to 20 db BELOW the noice-floor are actually the same as used by the people doing astrophotograhy to take pictured of very weak objects. As explained, you can probably match it to quite a number of different fields covered by FOSDEM. The fact is has been located near to the SDR devroom is simply historical.

Well, we can perhaps discuss this offlist. It might be usefull for backhaul connection (backbone) between repeaters but for the radio (RF) side, my impression is to use protocols specialised for that. On RF, every additional bit you need to transport requires extra RF bandwidth, which results in extra noise, a lower signal-over-noice ratio and therefor affects the ability to demodulate the signal. I will surely have a look at your website and your proposal.

Many more would probably qualify too - many people with certain degrees in physics or engineering can bypass the technical exam, e.g. in Australia: http://www.acma.gov.au/Industry/Spectrum/Radiocomms-licensing/Apparatus-lice...

In my personal opinion, it is one of the best ways for developers to gain practical insight into hardware and electronics and this makes all of us better at understanding entire systems end-to-end rather than being confined to one little silo on a project.

Has it been approved again in some form for FOSDEM 2016? 73, Daniel VK3TQR, M0GLR

Just to note, we'll be pitching another SDR devroom this year, as soon as the CfP is out. I'd like to keep the cooperation with you hams going! Cheers, Martin
