Getting into gnu radio, wanting to put my HackRF to use. Want to actually get a decent understanding of RF theory.
Messing around with GPS signals, going to try to work out autocorrelation and things.

Airframes Community forum, user 'thebaldgeek' reviews the Discovery Dish https://community.airframes.io/t/discovery-dish-rtlsdr-blog-l-band-acars/181 #SDR
Discovery Dish: a 70-cm aluminum satellite dish with an active filtered feed. Receives real-time weather data from GOES HRIT, GK-2A LRIT, FengYun LRIT, NOAA HRPT, Metop HRPT, Meteor M2 HRPT & more at ~1.69 GHz. Details: https://www.crowdsupply.com/krakenrf/discovery-dish #SDR
Your disaster kit needs a weather radio—it’s a lifeline for #NOAA and #FCC alerts in emergencies. But imagine getting not just audio updates but also images, charts, & reports off the grid. The future of weather radios: https://spectrum.ieee.org/software-defined-radio #SDR
The hardest thing about software defined radio is explaining to friends and loved ones why this is cool.
Finally got my Home Assistant to play nice with my RTL_433 to send me a notification when the smoke alarm triggers.

[New Blog Post] Measuring the Gain Pattern of a Yagi-Uda Antenna with an RTL-SDR #ham #sdr https://www.philipzucker.com/yagi_uda/
My school meeting was more adversarial than I'd anticipated, so I'm pulling a Scarlett & thinking about that... tomorrow.
Time for a productive distraction.
Anyone with specific resources for:
Building a wood/gravel foundation for a modular shed;
Identifying & tracking local train traffic via SDR (EOT devices maybe?);
Pretty, toxic perennials to add to my ̶p̶o̶i̶s̶o̶n̶ herbal remedy garden (SE Pennsylvania);
feel free to send them my way.
Does anyone know any #SDR tools (maybe a #GNURadio script?) to turn an SDR into a wideband scanner? Or is there a clever frontend device that can do that?
I have a nice SDR (LimeSDR Mini) that’ll do 20+MHz bandwidth and 0-3GHz, but what I really want is a visualisation of large chunks of spectrum (100MHz minimum, ideally full range) to identify congestion and rogue transmitters in our building on all ISM, FM, DECT, RadioMic, TV, WiFi, etc. bands.
I understand that it’ll be slower, having to sweep across the frequencies, but averaging over minutes is fine.
But there are spectrum monitoring devices around that seem to manage it somehow.
Costing but a few dozen coins, these enchanted boxes can pull whispers out of the aether. #SDR #RaspberryPi #OpenSource https://cromwell-intl.com/open-source/raspberry-pi/sdr-getting-started.html?s=mc

Finalizing the "Wall of SDR" ...
P25 in to Trunk Recorder
Multiple SDR into Kismet Wireless for 315/433/915/1090 and also a BT TIC for BTLE monitoring
Multiple SDR into SDR++ Server for local Amateur Radio Repeaters monitoring
Dedicated line to another machine for just specific testing.
And then finally documented.

Anyone know if I can use the same usb device to feed both #ultrafeeder and #acarshub? My gut feeling is no but figerred I'd check before trying to set another #sdr dongle up.

Ooooh, which one? I have a v3 RTL-SDR for VHF and UHF and a fancier AirSpy HF+Discovery that is amazing for HF work.
VHF and UHF are where commercial radio and a lot of air traffic live. It's generally radio line-of-sight. Handhelds of all types are usually one of those. Even if you don't have an RTL-SDR, their site has a lot of good info on general things you can do and find in that range.
