We will assume you have the RTL-SDR dongle set up and working already. Software such as WXtoImg for decoding the APT signal.A right hand circularly polarized antenna tuned to 137 MHz. A RTL-SDR dongle working with SDRSharp.To set up a NOAA weather satellite receive station you will need: YouTube user GaitUutLiern shows an example of receiving NOAA satellite weather images with a RTL-SDR, SDRSharp, a decoding program called WXtoImg and a QFH antenna. Also, an alternative tutorial for decoding NOAA satellites that uses rtl_fm can be found here. Note that if you have success with this tutorial, you may also be interested in decoding Meteor M N2 weather satellites which provide much higher resolution images. Hardware radio scanners can also work, provided the radio has a large IF bandwidth (30 kHz +) and a discriminator tap. This tutorial will show you how to set up a NOAA weather satellite receiving station, which will allow you to gather several live weather satellite images each day. Most parts of this tutorial are also applicable to other software radios, such as the Funcube dongle and HackRF and Airspy, but the RTL-SDR is the cheapest option. The RTL-SDR dongle combined with a good antenna, SDRSharp and a decoding program can be used to download and display these live images several times a day. Each NOAA weather satellite broadcasts an Automatic Picture Transmission (APT) signal, which contains a live weather image of your area. Everyday multiple NOAA weather satellites pass above you.
