WXtoIMG has lots of features you might want that noaa-apt does not have, for example false-color images, live decoding or map overlay.Īnyways, the quality of the black and white image should be the same. There are lots of really good Alternativesbut all of them require compilation, Python or don't provide graphical user interfaces. For convenience, you can use noaa-apt for resampling your files to any sample rate preserving the timestamps. I made noaa-apt because WXtoIMGthe most popular decoding software, it's propietary and no longer maintainedbut you can get old recovered versions from an unofficial website.Īlso, the steps required to decode WAV files on it are not that obvious. NOAA satellite reception is fun, cheap and relatively easy. Technical Data.When loading that file on noaa-aptyou get as a result this image. Recent Images received with the APT Small Size. Such antenna diversity based on noise evaluation is much more efficient than simple signal strength based circuits. The APTAD uses the noise value as switching criterion: A fast microprocessor continuously analyzes the signal-to-noise ratio and selects the less noisy antenna. The advanced model APTAD contains an Antenna Diversity Circuit, which under difficult reception conditions provides means to effectively reduce signal drop-outs and noisy image sections by using a second antenna.

Additional comfortable control functions are available with the supplied Windows program APT-Control.

Undisturbed by any other signals it reliably locks only to weather satellites and will not hang on other signals like simple scanners do.
#WXTOIMG REDDIT MANUAL#
Although the frontpanel button allows manual selection of the frequency channel, the APT will normally run in automatic mode: the WXtoImage software with its built-in satellite tracking module controls the APT so that the proper channel will be automatically selected for the next satellite to be recorded.Īlternatively the APT itself can search for active satellites with the built-in scanner. When connected to a computer via USB, no external power supply is needed.
#WXTOIMG REDDIT PORTABLE#
Therefore it is an ideal receiver to set up a mobile or portable weather station with a laptop computer, e.ĭue to the rugged, 2 mm thick anodized aluminum case, the APT is a very robust device. In the input RF amplifier, high-quality high-Q-filters with silver plated and shielded helical coils provide a very high immunity against interference from strong signals in the close-by aviation and ham radio bands. In addition, an active filter circuit carefully matched to the satellite subcarrier frequency is implemented to reduce remaining noise components. This eliminates noisy reception periods when the satellite is quickly approaching from long distance.

Satellite frequency Doppler shift is precisely compensated by a special AFC-circuit, which is fully active already when the satellite comes up over the horizon. Software options allow automatic creation of time lapse loop animations of NOAA satellite images. Therefore even nighttime satellite-passes deliver full-scale cloud- and temperature information. Satellite sensors deliver visible light as well as infrared images. Real-time images from several active satellites can be acquired about every 3 to 12 hours. American polar orbiting NOAA-satellites continuously deliver very sharp weather images all over the world. It feeds the received image data into the sound input of a computer for further processing so that an automatically operating weather satellite image reception station can be set up.
