RTLSDR-Airband VS raspberry-noaa-v2

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?

> NOAA and Meteor-M 2 satellite imagery capture setup for the regular 64 bit Debian Bullseye computers and Raspberry Pi!

The project was based on https://github.com/jekhokie/raspberry-noaa-v2

Here is the pic of the software setup. I have also used this on my computer using vmware and https://github.com/jekhokie/raspberry-noaa-v2. It handles all of the conversions and scheduling. I just had to play around to get it to setup on a non raspberry device. I included in the ticking system there how I did that.

I'm using raspberry-NOAA-v2 to automate the whole process, so yes I think it does do it via the command line.

I'm using raspberrypi-noaa-v2 to schedule and run NOAA and Meteor receives. I've got a brand new rtl-sdr-branded receiver and a bias-tee powered LNA, and am using the v-dipole antenna configured as instructed. My runs never show more than apparently random noise overlayed on the map. Can somebody help out a newbie to NOAA reception?

I have been using https://github.com/jekhokie/raspberry-noaa-v2 and i get the same kind of pictures. On this one i used SDR Console. It handles all the connection info and frequency/dopplar.

Buy that, introduce him to /r/amateursatellites, and have him use this (plus his existing raspberry pi) so he can receive weather pictures directly from passing satellites! I and others on that subreddit would be happy to help if he needs it.
