Satélites meteorológicos

These pages are dedicated to the reception of meteorological satellite image reception. I've been receiving these signals for quite a few years, and I've received a lot of requests for more information. I hope that these pages will be usefull in some way.

If you observe the images, there's a remarkable tendency for western passes (Pacific ocean and Chile). This is simply because my home is located on the side of a hill which effectively shields me from receiving to the East. Satellites must be above 20 - 25 degrees elevation on that side, while I receive well to 0 degrees on the West.

At my station, I'm using: A Quadrifilar Helicoidal (QFH or QHA), an antenna which is economical, relatively easy to construct, and gives excellent results.Here's a description and pictures. At the antenna, I've mounted a low noise amplifier with a GaAsFET transistor. A home-brew receiver with a TDA7000 integrated circuit (Now partially reconstructed and using an MC3361) The audio is processed with an SB compatible soundcard. PC K6/2 for processing. Wxtoimg (see links) program for the image acquisition
