raspberry-noaa-v2 VS airspy-fmradion

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.

I have a little hobby project where I record an FM radio music station using a SDR and then remove all the non-music portions for offline listening. I like the music selections the DJs pick, but I prefer not to listen to the DJ commentary and the advertisements.

I evaluated three methods of recording: analog capture from a standalone FM receiver, using this nrsc5 library to record the "HD" radio stream, and using an AirSpy SDR with this library: https://github.com/jj1bdx/airspy-fmradion

Recording the "HD" (what a misnomer) radio was nice in that there was no hiss or multipath effects, but in comparison to the other methods the digital compression artifacts became impossible to un-hear. It seems to top out at about 96 kbps

The airspy-fmradion library has some nice stuff in it to address multipath, resulting in the best audio quality of the three methods I tested.

I use https://github.com/ina-foss/inaSpeechSegmenter to identify which segments of the recordings are speech vs. music.

Alternatively, use airspy-fmradion:

You might want to look into using https://github.com/jj1bdx/airspy-fmradion instead of rtl_fm for stereo.

You can use https://github.com/windytan/wfm-tools together with rtl_fm to get stereo, though I prefer https://github.com/jj1bdx/airspy-fmradion
