WxToImg will listen to virtual audio interface and capture the data. WxToImg will send commands to MCE controller which will start rtl_fm and sox applications which will pipe the audio to virtual audio cable.

I assume you have Zadig drivers working already ( ) I found this post В which was poorly and incompletely written but it gave me a jump start. My SDRsharp was often crashing so I wanted to use rtl_fm CLI (command line interace) to receive NOAA images.

At $20 the rtlsdr is pretty much the cheapest NOAA APT / satellite communication receiver I have ever had. I hope this demonstrates that RTL SDR devices do have practical applications.

You can now clearly see the landmass and the clouds, as well as the reflection of the Sun on the surface of the ocean.

Below I have a вЂњHVC false colorвЂќ image where I have also applied histogram equalization: Wxtoimg can combine the different images to create various false color images. On the image above we see the infrared image on the left and visible light on the right. Often, one channel will contain a visible light image and the other will contain and infrared image. This is the image decoded by wxtoimg with the вЂњcontrast enhancementвЂќ option:ДЄPT transmissions from the NOAA weather satellites contain two channels that are basically two images from two different instruments. If you can make it work on your Linux box, it will provide you with many options for processing and enhancing the received APT images. Wxtoimg is a commercial APT decoder, however, it comes with a limited free version. The image was captured during a late afternoon pass, which is a good time for APT reception, because we can often see shadows beneath the clouds, giving the image a sense of 3D. Here is what I got from the recording of the NOAA-15 pass: It can decode the image but I have problems getting false color and temperature to work. The easiest and fastest way to resample the audio is using sox: sox input.wav output.wav rate 11025ДЄtpdec (probably misspelled version of aptdec) is an open source APT decoder which is no longer maintained.

Decode the image from the audio using atpdec or wxtoimg.

Use a sample rate that works well with your device on your computer (I used 1024 ksps).

With the latest rtl-sdr I had to use max gain setting.

Use the proper FM deviation (17 kHz) and filter width (45 kHz).

During this experiment I have used my Arrow II satellite antenna however, for a permanent installation a Quadrifilar Helix or a Turnstile antenna would be better.ДЄs written in the Funcube Dongle article, the procedure is to:

I suspect the recent gain improvements in the driver have something to do with it. Lets start with a video showing Gqrx receiving the APT transmission from the NOAA-15 polar orbiting weather satellite during orbit 73676 over western Europe:ДЄs you can see both the baseband and the audio SNR is rather good. Today, I tried to repeat the procedure using my ezcap eztv666 rtlsdr dongle with very good results.

About a year ago I posted a step-by-step guide about how to receive NOAA APT weather satellite images using Gqrx SDR and the Funcube Dongle.
