Location of the station that, on 12/5/2026 from 19:00 UTC, was transmitting the letter "V" on 5007 kHz, obtained using the TDoA extension of KiwiSDR network receivers.

El 27 de junio de 2026 la BBC tiene previsto el cese de las emisiones de Radio 4 que emite en 198 kHz en la banda de LF (Onda Larga). La LF se propaga de forma estable dia (hasta 2.000km) / noche (hasta 5.000km) por onda de superficie, asegurando la difusión www.bbc.co.uk/reception/wo...

Lots of interesting USAF military aircraft action over the Middle East, including this "Wi-Fi in the sky" modified Bombardier Global 6000. 24-9049 is an E-11A BACN (Battlefield Airborne Communications Node). Operating here over that Israeli "base" in Iraqi territory.

Intense weekend testing on the Raspberry Pi with an RTL-SDR. No luck with "acarsdec", but better results with "dumpvdl2", which received hundreds of aircraft messages, including ACARS. Still haven’t managed to integrate them into @airframes.bsky.social

For me it’s not a competition, but a form of enjoyment. Still, it’s nice to be near the top of the rankings, with EA5JTT receiving radiosonde packets and EA5RKP @radioclub-upv.bsky.social on WSPR.

I have two Raspberry Pis and four SDRs of various models (RTL-SDR, green clon RTL and clon RSPx). They’re the hardware I’ve enjoyed the most and gotten the most value out of. Here’s a summary of my experiences with them over the last few years ea5jtt.blogspot.com/2026/05/rasp...

I was going to set up a @meshtastic.org network for testing, and while I was doing that, I thought about also setting up @meshcore.bsky.social to compare them. That's what I was doing when I read about Reticulum My life is in turmoil.

USAMOS LA TÉCNICA DE DISPERSIÓN HACIA ADELANTE #ForwardScatter para rastrear el fenómeno meteórico. Ayer Xema Oncins desde Zaragoza y Azahara López del Aula de Astronomía de Fuenlabrada captaron este eco #SPMN050526C al unísono. Pero, ¿no había detección en el NO peninsular...?🤔

Web888, the clone of KiwiSDR, has the feature that it receives HF from 1 kHz to 62 MHz and VHF from 118 to 150 MHz with separate antenna inputs. In this way, using the WebSDR at hb9re.ddns.net:8083, we can listen to all operations at Zurich Airport ( VOR, ATIS/VOLMET, radio communications, etc.)

Una aplicación muy útil de la red UberSDR es la que permite conocer que estaciones reciben una señal proporcionando su frecuencia. Siguiendo con el ejemplo he preguntado por la de 252 kHz instances.ubersdr.org/signalfinder...

KiwiSDR vs Web888 El original ha muerto de éxito, con constantes cortes en el suministro, frente a la abundancia del clon que ha visto la oportunidad. Esperar o comprar, that's the question. ea5jtt.blogspot.com/2026/05/sdr-...

Alex EA5HJX, who’s a real tech whiz, told me about using the KiwiSDR network for geolocating transmissions (TDoA: Time Difference of Arrival). I tried it with the 252 kHz transmission (Chaîne 3, Tipaza, Algeria 36,57⁰ N 2,58⁰E) and got very good results. A whole world to experiment with.

In 2025, the European ocean region experienced its highest annual sea surface temperature on record, the 4th consecutive year of record warmth. 36% experienced ‘severe’ or ‘extreme’ conditions. Read the European State of Climate #ESOTC2025 ↪️ bit.ly/ESOTC2025

After installing radiosonde, AIS, and APRS receivers in my Raspberry Pi with SDR-RTL, it was time for ISM, and the experience didn’t disappoint. ea5jtt.blogspot.com/2026/04/inst...

Que alegria escuchar la emisora de música POP "Power 927" (Brings the Medium Wave Back to Life) que desde el norte de Italia transmite con 1kW en AM en los 927 KHz www.facebook.com/share/18diWb... Sintonizable desde: Milán milano1602.dyndns.org:8073 Cassale Monferrato i1fqh.proxy.kiwisdr.com:8073

For a talk on SDR at @radioclub-upv.bsky.social , I prepared a short list with some examples of types of transmissions from around the world that can be received via remote SDR receivers and servers. Enjoy! P.d. Suggestions are welcome and may be added. ea5jtt.blogspot.com/2026/04/emis...

On a @raspberrypi.com where I had Pi-Star installed for DMR, I thought I could install radiosonde_auto_rx as a service to track radiosondes and use of SDR & antenna. Encouraged by the success, I installed @direwolfdigital.com to APRS, and now I installed rtl-ais to track AIS signals from vessels

Dado que hay costelaciones de satélites (p.e. Starlink 10.000) de baja órbita (unos 500 km) que permiten que desde un mismo punto del planeta se vean simultáneamente varios de ellos (hasta unos 15) es posible que los satelites pueda monitorizar (espiar) en tiempo real un punto concreto. Fin
