To set this in Windows, right click your device in the Windows sound recording tab, go to properties and under the advanced tab, set the sample rate to 48000 Hz. Do the same to the same device under the Playback tab as well.Īlso, in your SDRSharp folder, open in a text editor such as Notepad, and ensure the key minOutputSampleRate has a value of 48000 such that the line reads as . The sampling rate of your audio piping method should be set to at least 48000 samples/sec. You can use either windows stereo mix, VB-cable (free) or virtual audio cable (paid with trial version). Audio piping will allow the audio from SDRSharp to be passed to a decoding program. You will also need to have an audio piping method installed and set up. If you have not bought a dongle yet, see the Buy rtl-sdr page for information, and the check out the Quickstart Guide for an easy setup routine with SDRSharp. We will assume you have the rtl-sdr dongle set up and working already.
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, 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.
