 So, the software-defined radio deaf room has been at Foster for multiple years now. This is the, I think it's the fifth run that we're doing, and it's always been a huge success. So, this room usually fills up pretty quickly. By the time the second or third talk is happening, it's usually full and then it stays full until the end. And it actually stays full until the end. So, it's not like we finish at 4.30 because we ran out of presentation. So, that's never happened. And it's not going to happen this year either. So, I'm very, very happy about all of that. Now, what I'm particularly happy about is like just the spectrum of talks. So, as you see, I actually prepared an intro talk this time. So, this is a screenshot from the website, the current schedule, and this is actually useful information because this is what we'll be talking about. But what I wanted to highlight is like where all these people are coming from, what domains. So, we have sort of like sorted them by topics. And you can already see just based on the topics, there's like a very, you know, big variety of talks. And it's all under sort of the big umbrella of software defined radio. So, we have, you know, actual sort of wireless comms, DSP problems. But there's also like some community related talks. InfoSec security is in here, you know, hardware. We usually had more hardware talks that we have at least one this year. So, we've never had zero. So, that's very cool. Education is something that I'm personally very passionate about. So, I'm very happy that we have talks on that topic as well. But there's another way that you can look at this presentation, sorry, this list of speakers. And that is trying to see where they come from. So, I'm going to turn around now. And this is also something I'm very happy about. So, we have sort of non-profit organizing. We just have like straight up, you know, enthusiasts. The people who do something completely unrelated to SDR and their day job. But they're still interested. So, they come here and talk about it. We have people who sort of are government affiliated, academia affiliated when there's a bit of an overlap there. I realize that people from industry, you know, who get actually sent here by the employers. And yeah, I think that's great. And that's really what makes this deaf room so special. So, this is not a radio conference. This is also not an Osmo conference or something like that. This is like everything that falls under sort of the common intersection between radio related topics and free software is like welcome in this deaf room and then we all get together. And I think that's not cool, but it's also important because this is a forum where we can share not only ideas, but also sort of project plans. And that way can avoid reinventing the wheel. Because one of the things about open source and free software development is it is true that most of it is actually these days paid work. But it is still work that is typically done by people who are passionate about things. So, if you sort of burn like that enthusiasm and energy by reinventing the same thing twice, like you've just wasted a lot of productivity. So, I really hope that we can use the deaf room as we do every year to exchange ideas about all these domains. And yeah, and I just think it's a great opportunity. We don't really have any other venue like this. So, that's another reason where I'm so glad that we keep doing it. Okay, I actually prepared a couple of slides where I'm going to have to blast through them now because I was late. But I still think they're interesting. So, I'm just going to quickly mention it. There's a couple of interesting highlights that happened in the last year. And this is a slide I had to put in very recently. So, because the GNU Radio Organization, while I said this is not a GNU radio conference, GNU Radio is still a big, important project in the whole free software, software radio domain. So, yeah, there was a recent change in the sort of leadership. There were emails out on the mailing list. Ben explained it all. And Ben, of course, is still in charge of the project, but Jonathan Corkin stepped down. And we used the opportunity to get a couple of people more involved. So, among others, Marcus, for example, and Andre, I saw him somewhere. Oh, there. And, yeah, there's a couple of other people. Derek, is Derek here? Not yet. A couple of people, I listed them here, will become more active. And, you know, we'll have more defined roles going forward. So, this is, you know, it's sad to see people leave like Jonathan, who's been putting in a lot of work and money over the years. But it's also a natural cause of events. So, we're glad that we can sort of handle it in an organized fashion. So, that's one thing. And, speaking of events, we did have GNU Radio Conference 2017, which, because we don't have this sort of general SDR conference, like GRCon has become a little like that. So, it used to be just GNU Radio topics, and now it's a lot more just like, you know, software radio related topics. It's still mostly focused on GNU Radio, but like the amount of people that come are great. And, like this event, like what I like most about GRCon is that we have this big mix of like people who come from hackerspaces, but then also like big companies who, you know, just have to go to this conference because it's become like de facto, like SDR, like conference. Yeah, and here's a couple of screenshots because we have all the videos uploaded from Fearless Leader Ben and our new maintainer Marcus. There's the DARPA hackers, I'm not going to talk about that because we have an entire talk about it, but I did want to put it on these slides because I think it's an important event, an important event for many reasons. One of those reasons is the fact that the, it's a statement that the US government sort of acknowledged the fact that this whole open source thing is important and it's worth investing money in. But, as I said, Tom will talk about that. SDR Academy is part of the Hamrader Conference in Germany. It's not a huge event, but what I like about that is that it's sort of, it's an active step from the Hamrader community to get closer to the SDR community. And that's like, those two communities have been very separate for a long time for no good reason, other than like the people who join those communities are typically from different backgrounds. Those videos are also up online. Okay, and there was plenty of other events. I just picked like several, there's like local small events, Rotor Schwartz Engineering Competition I thought was worth mentioning because this is just, this was a fantastic event organized by a company that we haven't really seen in this domain before. And it, yeah, just look it up, it's pretty cool. You know, the Congress is, you know, always has SDR related content and plenty of others. I started making a comprehensive list of everyone who's now active in the SDR. I mean, I just gave up eventually, it's just too many. And that's a good thing. And not only are these like lots of different groups, but also there's a lot of overlaps. So for example, these guys use GNU radio. They do their own thing and they have a presentation later, but they said like the whole SDR stuff, like that's the solve problem, we're going to latch onto that. So this is not a competition between, which is just like an expanding space of enthusiasts in different domains. We have some new hardware. Robin will talk about Pluto. Lime SDR is no representative, I'm afraid. So Edis Research is going to, is will be releasing another product in the next two weeks. I probably forgot some here, but that's also interesting to see that we have like a much bigger spectrum of available options other than just like USUPS and HLSDRs, although of course you should all buy USUPS. No, I'm just kidding. Finally, there's one thing that I quickly wanted to mention. So we used to have a panel and I didn't, I think they usually went well, but they took up a full hour and they took away from talks. This year we don't have a panel, we have an interactive half hour at the end. So if you just want to show off stuff or just ask people questions, that's a good place to do that. And yeah, again, this is the schedule, so we'll have a Tom first, then John Michelle and then myself again and then yeah, you can see the rest. So there's no break here if you want to have lunch, just like pick one of the talks you're least interested in and then use that. This room as I said typically fills up, so if you leave you might not be able to go back in. Remember we have like very strict rules like with respect to fire regulations and all of that, so we have to stick to those. But we can squeeze a small number of people in the corners like I say like fullness like this, we could probably add another 20 people or so, but then that's it. So there's no guarantee that you can come back in, but then fresh air is also a nice thing. All right, thanks everyone. I'd like to welcome all the speakers. I'm just going to hand off to Tom right now, wait to see us.
