Radio frequency path loss prediction using software simulation
This is done using pycraf, a python library used to predict how radio frequency emissions may propagate and affect other installations.

802.11ah Wi-Fi HaLOW: The 1 Kilometer WiFi Standard
I 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.

Need Help Interpreting H-line 3D Corner Antenna Signal
You'll find the H-line-software on : github.com/byggemandboesen/H-line-software. There is a requirements.txt file which will install the necessary Python packages. Python3 is afaik also available on github. But you can just google 'Python3 download'.
- Anyone done anything with Hydrogen Line on 1420Mhz?

H Line observations and question
For anyone wondering what software we're talking about, here's a link to the GitHub repository. I am planning to do some updates to it in the near future for better performance, better looking observations/plots and a more intuitive UI.

Beginner looking for feedback on antenna/horn for
Then I found H-line-software (https://github.com/byggemandboesen/H-line-software). It's running without GNU radio and makes interval reading for 24 hr with automatically produced GIF animation from the spectrums. So you can see pretty clearly how the Milky Way drifts over you. A small map shows to where your RT was pointing while reading. Scrolling down this subreddit you will find several posts with images from out of this software.

My hydrogen line data over the past few days. I’m working on a map of our galaxy. Only 3 tilts so far but I’m working on getting a motor and making some tilt controllers. (More info in comments)
I have a wifi grid antenna into a nooelec SAWbird+ H1 into a nooelec SDR + some cables. I’m using https://github.com/byggemandboesen/H-line-software to receive/graph basic graphs and then my own webpage with the Plotly JavaScript library to make my map

Trouble With Hydrogen Line Readings
I, however, want to ask about how you're trying to detect the hydrogen line peak? Are you using software like SDR++, SDR# or similar? I that case, I would propose trying to use custom software dedicated for H-line astronomy. The hydrogen line is still quite weak and it often requires an average of multiple FFTs. For that I'd advise my own software which will work with a couple python libraries and run on Linux, windows and etc.

Hydrogen Line Radio Telescope
You probably need to look at the Soapy SDR interface in that case. Other pre-made projects are Virgo, Pictor, and my own software (which unfortunately only supports RTL units) https://github.com/byggemandboesen/H-line-software
