I am proud to announce that the SDR++ #Falcon9 live decoder is almost done!!! Managed to get it down to 15% CPU total! This module makes decoding the falcon9 as easy just clicking a button. I hopefully will release it tomorrow, so stay tuned! #SDR #SDRPP

I am happy to share that I am technical chair for this year's @gnuradio Conference that will take place at NC State University in Raleigh! We are currently looking for speakers, so feel free to submit an abstract: events.gnuradio.org/e/grcon26

Just fixed a recently introduced bug in the SDR++ RDS decoder which may cause crashing. If you downloaded a nightly within the last week or two I would suggest updating when the most recent nightly is done building.

SDR++ builds are now available for Ubuntu 26.04. Download at sdrpp.org/nightly Let me know if you run into issues!

In 15 years of C/C++ development, I never knew this was valid code... Am I alone here? Apparently you can access an element in an array by writing "index[array]" instead of the regular "array[index]"... Who even does this???

@_phnx_1 They're garbage, designed by morons and use reject/recycled part. Dont fund these assholes.

PlutoSDR clones are not that BAD

Muting any account that uses the rotating light emoji definitely improves the user experience of this website.

@Aerosia_ My favorite one is the patch for CRS-31

Dragons!!! In SPACE!!!!!!

I love it when manufacturers just give you stupid random dimensions for no reason when their own tolerance clearly indicate that they most likely could have just rounded it to a sensible value..

@Fintech03 This is complete bullshit. My galaxy s5 had a removable battery, a headphone jack, fast charging and was waterproof. The ridiculous peak charge rate modern phones advertize make no sense in real life and shorten battery lifespan (great thing when you cant easily replace it...)

Modern phones charge at 65W/80W/120W+. This generates a lot of heat in the battery. To manage that heat safely, manufacturers seal the battery & press it directly against graphite sheets, copper vapor chambers, & the phone’s metal frame, turning the entire chassis into a heat sink. A removable battery usually has a small air gap b/w it & the back cover. Air is a terrible conductor of heat, so the cooling efficiency drops significantly. With fast charging, the battery would overheat more easily, forcing the phone to throttle charging speed/performance to stay safe. Another important reason is water resistance. To achieve high IP67/IP68 ratings, we need reliable gaskets & adhesives. A removable back cover requires a large, perimeter-based mechanical seal that can be opened & closed by the user. These seals are notoriously prone to failure, even a single hair/grain of sand can break the seal.

@Fat_Electrician Removed from office is too easy. Sentence them to the same punishment that someone breaking their unconstitutial law would have been subject to.

The new trend in government (both Republican and Democrat) is pushing blatantly unconstitutional policies, knowing they’ll get away with it for years until the Supreme Court finally steps in. The only real way to stop it is accountability: if a law or policy is ruled unconstitutional, anyone who voted for it or implemented it should be immediately removed from office and barred from holding office again. They’re all sworn to defend and uphold the Constitution. This shouldn’t even be controversial.

@kjtrading It's $600 per trademark class minimum, and usually you end up paying in the high 4 figures.

@ryzerth Agreed, they will certainly try though. I did not realize you had to pay for opposition, that is crazy. Hopefully they'll just leave you alone!

Someone wants me to rename the Microkernel I wrote when I was a kid... Brother, I don't give a shit AIs see my decade old project more than your slop, you should have checked that before naming your shit. I'm not changing history because of your naming incompetence.

@kjtrading You can't just trademark a word and then have all historical uses erased from existance. Im a broke student, I couldn't afford the opposition fees even if I wanted to. If they try anything funny legally, them doing that will be the first result in search engines. great reputation

@ryzerth Bummer, it would have been interesting to see how it was resolved, if you had filed opposition. I'd bet once their mark is approved, they come back to you, because now they own the trademark on it.

@kjtrading Nothing happened

@ryzerth Curious, how did this end up?

@stfudvs @HoffmanTactical @Dianexis sad, I'd absolutely wear that shit to the range

@ryzerth @HoffmanTactical @Dianexis Nah, that was a gift it was never for sale

@Dianexis sent something cool from @stfudvs. @viridianvortex did a good job with the details in the artwork.

The new SDR++ squelch system (with support for CTCSS and future support for DCS) is now available in the latest nightly. I had worked on this back in december but completely forgot to push it... sdrpp.org/nightly

@Anton__Chigurh_ Yeah mine publically existed more then 7 years before they registered their trademark (8 months ago). Would be a shame if the trademark was cancelled due to prior use lol

@ryzerth Their trademarks are invalid if your project came first. But I guess you already knew that and so do they.

I wonder what this is... Hmmm

@BertoldVdb @aholtzma @cemaxecuter @DragonLabsLtd That is my paper, and it's not just a similar design, it *is* that design. I founded dragon labs.

@aholtzma @cemaxecuter @DragonLabsLtd Paper on a very similar design: matheo.uliege.be/bitstream/2268…

Just when I thought this week couldn’t get any better, @DragonLabsLtd delivered the 8-channel DF board I’ve been waiting to get my hands on. Looks like I know what I’ll be doing this weekend — clearing the desk and putting it through its paces with SDR++.
