The APT weather facsimile (WEFAX) images can be decoded using specialized weather satellite equipment. An inexpensive alternative is published by
Eugune Ruperto in the August 1997 edition of QST magazine (pp. 36-39) titled: An Easy Way to Copy the Weather Satellites. This involves decoding the WEFAX information through a Soundblaster®
compatible sound card on a computer. The audio from a radio tuned to the appropriate frequency is input to the Line-in or Microphone jack on the sound card. The WEFAX imagery is then decoded by a freeware program
called WXSat, written by Christian Block. This software can be downloaded from Eugune Ruperto's Web page.
Eugene Ruperto also published an excellent article in the August 1996 edition of QST magazine (pp. 30-34) titled: The W3KH Quadrifilar Helix Antenna.
This article provides detailed instructions to construct this antenna which is excellent for LEO weather satellite reception.
The Remote Imaging Group Web site and the Dallas Remote Imaging Group Web site are other excellent source of weather satellite information.
