ALTERNATIVE TO WXTOIMG FULL

ItвЂ™s still a relativelyВ low cost item at about ВЈ40 delivered to the UK but itвЂ™s the most expensive component in use here.

My one extravagence in this setup is the inclusion of a Low Noise Amplifier (LNA), specifically an LNA4All. Nevertheless, the QFH antenna seems to do quite well. Over time this will be compared against the active V/UHF antenna I have installed my chimney. ItвЂ™s a compromise and really just a first attempt to get something up and running.

The antenna is mounted deliberately low on my garage to avoid exposingВ it to the full breadth of pager interference in the local area. IвЂ™ve added some extra horizontal struts to keep the helix shape better in the wind and also strengthened the main mast by inserting a steel clothes rail (a perfect fit into the plastic pipe) inside the lower section of the mast where the clamps are holding it to the wall bracket.

The antenna IвЂ™ve built for this purpose is a Quadrifilar Helix (QFH) type based on G4ILOвЂ™s notes. OK, letвЂ™s go through it in a little more detail belowвЂ¦ Antenna This allows me to easily sort through the (many) noisy images of low elevation or night-time passes and recognise the passes that have produced good images for further processing. A couple of Python scripts also run on the RPi3 to control automatic recording of the satellite passes and process the recorded files, opening them in Wxtoimg for decoding into basic images and then upload to aВ website for review. Basically a Raspberry Pi 3 (RPi3) is the star of the show running the satellite prediction software, software-defined radio and image decoding software.

One of the aimsВ of my setup is to see what can be achieved at low cost to support a school project detailed elsewhere on this site. ThereвЂ™s lots of tutorials out there on the web about the many methods there are of receiving these signals so I wonвЂ™t replicate those here, this page is intended to outline my particular setup and show some of the results. These are surprisingly easy to receive with basic equipment and provide really interesting imagery of the current weather overhead. IвЂ™ve been spending a lot of time over the last yearВ playing with weather satellite reception, specifically the NOAA APT satellites, NOAA 15, 18 and 19, that broadcast their imagery in the 137 MHz band.
