RTLSDR-Airband VS nrsc5-dui

You're all correct, except there are not that many $30 SDRs out there. Also, most SDRs have clearly superior capabilities to the RTL-SDR, though those capabilities often are not required.

BTW, for simple AM/FM demodulation I cannot recommend enough the handy https://github.com/charlie-foxtrot/RTLSDR-Airband. For example most of LiveATC.net feeds run on it.

rtlsdr_airband, but again requires knowing the frequencies of interest ahead of time.

You may want to give RTLSDR-Airband a look. Its designed for analog AM/NFM voice traffic and can be configured to operate on any frequency your rtlsdr dongle can handle. It can also be configured to output to an mp3 file, in addition to other things like IceCast.

There’s an example service config file in the repo: https://github.com/charlie-foxtrot/RTLSDR-Airband/blob/main/init.d/rtl_airband.service

I have been streaming the output from RTLSDR-Airband (https://github.com/charlie-foxtrot/RTLSDR-Airband) with icecast2 for several (5?) Years now, and I have some time and inclination to look at reducing latency (currently best is 10s, but often much more.)

https://github.com/szpajder/RTLSDR-Airband Might be what you are looking for, although I don't know the performance requirements. It has a scan mode detailed here: https://github.com/szpajder/RTLSDR-Airband/wiki/Configuring-channels-for-scan-mode

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?

and sometimes I use https://github.com/markjfine/nrsc5-dui when I want to see the weather and traffic maps . honestly they are worse quality compared to the weather network for local coverage but it is a neat demo

After a lot of searching and testing I came across the developer Markjfine and after trying to make nrsc5-gui to work well he decided to fork the project to nrsc5-dui. Nrsc5-DUI is a fork of a really old version of nrsc5-gui that is not dependent on python audio processing which caused a lot of issues with modern versions of nrsc5-gui. Like the old version, it still uses python, it's still licensed as GPLv3, and has a similar interface. However, Nrsc5-DUI has plenty of new features and improvements such as better audio processing, better channel switcher, more station information, the option to pull album art from Discogs (currently broken due to Discogs anti-bot), better map displays, cleaner code, and optimizations for Python 3.9.
