I'm so happy to see you working with Balint! He's done so much for the SDR community over the years. If you'd like to help his family, he's running a donation for Rett Syndrome. I'm sure raising awareness of Rett Syndrome would mean a lot to him and his family.

There’s a little inside joke in the GNU Radio community. Inside GNU Radio Companion, you can turn on a display of your flowgraph complexity. The units are in “ubal”, which is short for “micro-Balints”. Because Balint was (and clearly still is!) famous for his very complex flowgraphs!

This is true, Balint told us he had the unit of flowgraph complexity named after him!

When Marc first talked about the satellite my first thought was "OMG some nerds went rogue and used Linux to tell an ancient satellite to fire its thrusters!" Which is exactly what happened but they got permission first. I'd love to hear what an old Nasa Engineer thinks about the small book sized SDR doing the same work as the room full of old hardware. Amazing to think about.

This was just amazing! It really puts into perspective the difference between the older tech and new things like SDR, which in turn shows just how incredibly advanced the Apollo equipment was, to be able to do what it did back in the 60s.

This S-band stuff is so cool. I used to tinker back when satellite TV was still using some of that equipment. I don't know why, but it's very satisfying capturing signals from space. I really got interested in this stuff back in the late 70s when our high school had a guy from NASA show up to do a presentation with a bunch of telemetry equipment which he demonstrated. Most of the kids were unimpressed but I was on the edge of my seat! He even demonstrated some of the spacecraft sensors and I remember being blown away by what they could do.

That was fantastic! Shows how much the technology advanced but also how pretty advanced they were back then despite the bulky equipment they had. The beauty of it all is that the space program made it possible that we have this SDR and other technology now. Kudos to them and to the team that is "re-doing" all that.

You really can do pretty much anything, demodulate to pretty much any format, and with the right frequency multipliers/dividers to stay within the range of your SDR box you can act across pretty much the entire radio and microwave spectrum. Compared to having totally different circuitry to handle different bands and modulation schemes… it’s quite intense
