![]() This is the final image for my recording: NOAA weather transmission received on at 1410 Hrs using RTL SDR dongle. You can go to file menu to save the image to your preferred location. Once the Satellite pass time is completes WXtoImg will autoprocess the audio file to decode the image data and show you the image. ![]() The audio sounds like this: ///wp-content/uploads/200840.mp3 As the satellite passes from your location it will capture the image and start transmitting and you will start receiving the audio. For me it was 137.1000 Mhz for NOAA19, put SD# in WFm mode with around 35Khz as bandwidth and wait for the transmission to start. Go to SDR# and set the frequency of the transmission. once it comes close select Record option and set to Autorecord. now wait for the time the satellite is going to pass over you, use the Satellite pass-list option from the WXtoimg under File menu to see the local time of the pass. With this you are all set to receive the signals from SDR# to yoyr WXtoimg. the audio level in WXtoImg is shown at the right bottom corner of the screen and it should be around 50 atleast. Start SDR# and come back to WXtoImg and test record to make sure the it is getting the signal from SDR#. Once this is all set go to SDR# and make sure your AF Gain is good enough. What this does is, it creates a virtual audio cable to transmit the signal from the SDR# application to the to WXtoImg application. ![]() Go to WxtoImg, under Option go to Recoding Options and under Soundcard select Cable Output. In SDR# you have to select the output under Audio settings as Cable Input: To start with Install the VA-Audio application from this link. ![]()
