Speaking of #SDR #classroom settings: GNU Radio's chat servers have a room, dedicated for coordination, mutual support and curriculum development between #educators; `#edu:gnuradio.org` on Matrix ( @matrix ).

There's a whole load of special-interest topic rooms, like radio astronomy, ham radio, specialty development topics…, which you can find in our community space on Matrix,
`#gnuradio-community:gnuradio.org`

Tonight I RFI hunted one potential location for my Discovery Dish Hydrogen Line Radio Telescope. RFI sweeps were performed with my HackRF, and Airspy on a dummy load and a 1420 MHz whip antenna purpose built to detect RFI.

jansky-observe dashboard proudly announced HI DETECTED 🧐 from a 50 Ω terminator? it was the receivers own spur at 1421.484 MHz

I learned about LO-shift spur discrimination today 🥳

The GNU Radio Conference 2026 #GRCon26 schedule is officially live!

https://events.gnuradio.org/event/28/timetable/#all.detailed

We're looking forward to 56 #conference sessions in Raleigh, social events, an ever-popular capture-the-RF-flag tournament, workshops that would cost an arm and a leg elsewhere, and by a margin of 39.5% the by far best hallway track in #SDR!

Estábamos configurando la radio SDR que se compró mi cuñado, y encontramos una señal de radio entre las radios Universo y la Rock&Pop ... ¡al parecer es una radio pirata! se llama MARAVILLOSA FM en el 93.9 del dial de Santiago de Chile.

¿Alguien más la escucha? Leyeron un whatsapp al aire de un oyente en Macul.

T-Mobile's 2G/GSM network has been shuttered in Boise Idaho

is there already some statistical pattern recognizer (aka AI before the times of LLMs) that automatically guesses modulation of radio signals? working with #rtlsdr or with #gnuradio?

update: and automatically decodes the signal into files?

When you have a radio that is accurate to 1 times 10 to the negative 13 hz per 24 hour period thanks to a very expensive, ultra stable, crystal and some awesome gps tech, and it all just works, you know the software you're working on, the accessibility you've been literally dreaming onto disk, is worth the hours. Tomorrow, I write firmware to my radio and a remote radio from my servers, then, I implement incremental backup, then, I conquer the radio world with accessible technology, and it all started with Jim Shaffer's vision and code. Jim, we miss you buddy, this is all in your memory and honor. JJ flexible with multi radio support lands publically by end of year and I can't wait for everyone to experience it all. #JjFlexible #HamRadio #flex #sdr

I'm excited to announce a new Rust crate for forward error correction. It supports convolutional codes (with SIMD accel on nightly) and Reed-Solomon. It comes with a libfec-compatible C shim and benchmarks ahead of libfec on every code.

Сонар из Музыкальной Колонки

В этом тексте я написал про то как упражняться в радиолокации на основе экспериментов в акустическом диапазоне. Я собрал прототип сонара и попробовал определять расстояния до условных целей.

Hackaday Europe 2026: High Performance SDR On The Cheap

https://fed.brid.gy/r/https://hackaday.com/2026/07/27/hackaday-europe-2026-high-performance-sdr-on-the-cheap/

I think it's so cool that from my house in Nottingham, with a cheap SDR dongle and the included antenna I can pick up ADSB signals from aircraft over a hundred miles away and then plot their details on a map with an opensource tool and a bit of HTML. #SoftwareDefinedRadio #SDR #RTLSDR #Radio #aviation

Wegen dem #Sabotage #Stromausfall im #Berlin stehen 4 Beschuldigte im Verdacht....

...Es sind hochentwickelte elektronische Geräte sichergestellt worden. Diese hätten dazu gedient, #Kameras, #Wanzen und #Mikrofone aufzuspüren. Alles deute auf ein #hochkonspiratives Vorgehen hin....

Ich muss auch ein Linker sein.

Ich bin ein #Elektronik er und ein #SDR reicht dafür ja auch schon....

Anyone have any idea when the Dragon Labs CR-8's CrowdSupply campaign actually launches?
The page is still just the marketing stuff and "This project is launching soon."
