>> or somewhat expensive and complex SDR
I don’t think that’s as accurate today as it used to be.
On the hardware side there are tons of options very cheaply available - iirc the flipper uses the c1100 (or a number like that) it’s a popular cheap chip and it’s well documented and interfaces easily with arduino.
More accessibly, lime mini SDRs are cheap but there’s quite a few alternatives too.
On the software side GNU Radio is free with decent tutorials - we’re not talking anything like blender levels of difficulty to adopt even if it is a complex domain.
Although on the more accessible side, urh is incredibly powerful given how easy to use it is https://github.com/jopohl/urh
I used the latter to tap into a 2 channel wireless bbq thermometer via a $10 rtl sdr and that was a breeze, an absolute walk in the park compared to when I reverse engineered the flysky telemetry system.
Repurposing WIFI and DVB-T receiver devices as SDR receivers works "OK", but trying to use a SDR for WIFI is terrible. There have been some attempts to analyze WIFI with the HackRF, but the narrow bandwidth/sample rate make it pretty useless. https://github.com/ghostop14/sparrow-wifi

From https://github.com/markjfine/nrsc5-dui#maps :
> Maps: When listening to radio stations operated by iHeartMedia, you may view live traffic maps and weather radar. The images are typically sent every few minutes and will fill the tab area once received, processed, and loaded. Clicking the Map Viewer button on the toolbar will open a larger window to view the maps at full size. The weather radar information from the last 12 hours will be stored and can be played back by selecting the Animate Radar option. The delay between frames (in seconds) can be adjusted by changing the Animation Speed value. Other stations provide Navteq/HERE navigation information... it's on the TODO 'like to have' list.
Is this an easier way to get weather info without Internet than e.g. Raspberry-NOAA and a large antenna?

> NOAA and Meteor-M 2 satellite imagery capture setup for the regular 64 bit Debian Bullseye computers and Raspberry Pi!
The code of nrsc5 (and my transmitter project, https://github.com/argilo/gr-nrsc5) would be the best source of information for the undocumented parts. I do have some private notes, but the useful information has already gone into the code.
Project mention: 802.11ah Wi-Fi HaLOW: The 1 Kilometer WiFi Standard | news.ycombinator.com | 2024-01-08I observed the "H-Line", https://en.m.wikipedia.org/wiki/Hydrogen_line
Made a GIF of the transit of the milky way using this software on a raspberry pi with some SDR/RF equipment. https://github.com/byggemandboesen/H-line-software
Unfortunately I only have some images on my phone right now, a git page is on my todo.
Thanks for those references! I wanted to see what an SDR radio time signal detector would look like, and looking for "DCF77 sdr python" pointed me in the right direction -> [0] and [1]
A bit unrelated question: there are many web SDRs that let you listen to radio frequencies/stations such as [2]. Are there web / Emscripten SDR decoders that run in-browser? i.e. a full browser listening + decoding experience? For example, decoding the DCF77 time signal, or even just morse code?

I've done it a couple different ways, but there are likely better methods that I'm not aware of though. You can get the magnitude, use a threshold block, throw away 1 in every N samples so it aligns with the bit rate, tag the start of the message with a correlate access code block if it always has a preamble, and then build a decoder block to check for the tag and work with so many samples after that. See the decode flow graph for this: https://github.com/cpoore1/gr-X10
