Note that the NOAA book is *FREE* for anybody who requests a copy. -------------------------------- cut here -------------------------------- Other Resources The American Radio Relay League (ARRL) sells the "Weather Satellite Handbook" for $20 describing how to receive signals from all of the different types of civilian weather satellites. An optional diskette is available for $10. While the book is in its fifth edition it shows its age. The early chapters have good reference information on weather satellites, how they work, the types of hardware required, directions for a homebrew turnstile antenna, and radio requirements. But ignore the chapters on building a hardware interface or manually plotting a satellite's orbit. While still technically feasible they're rather impractical and can easily be replaced with a $30 Soundblaster card and freeware satellite tracking program. The "User's Guide for Building and Operating Environmental Satellite Receiving Stations" is published by NOAA. It's an excellent reference source with many useful hints and techniques. Like the ARRL book it includes information on manual satellite tracking, but at least it acknowledges the widespread availability of satellite tracking programs. The WX SAT E-mail list consists primarily of amateurs exchanging information on weather satellites, tips, and advice. It also includes operational bulletins. To subscribe to WX SAT send E-Mail to "firstname.lastname@example.org" with blank subject line and "subscribe your name" as the message (where "your name" is your actual name). -------------------------------- cut here -------------------------------- Internet WorldwideWeb resources of interest - Laura Halliday VE7LDH's weather page - interesting information about one person's approach to inexpensive weather satellite imagery http://mypage.direct.ca/v/ve7ldh/wxsat.html Chuck Vaughn AA6G's page - excellent images http://www.aa6g.org/weather.html an excellent set of links to assorted weather satellite pages http://ecco.bsee.swin.edu.au/chronos/metsat/metsat-own.html an excellent set of links to assorted weather satellite pages http://ourworld.compuserve.com/homepages/hffax/TOC4.HTM tutorial on building a portable APT station including building a portable turnstile antenna http://psbsgi1.nesdis.noaa.gov:8080/EBB/pubs/sympos/symp33.html An excellent reference for scanner modifications to increase the bandwidth http://ecco.bsee.swin.edu.au/chronos/metsat/cheekmods.html A schematic for a 137 Mhz. filter http://ourworld.compuserve.com/homepages/sesteban/ifilter.htm FTV (DOS) http://www.geocities.com/SiliconValley/2504/ WXSAT (windows) http://members.aol.com/jkktl/ham.htm RadFax (Macintosh) ftp://ftp.demon.co.uk/pub/ham/mac/RadFax09.sea.hqx Latest two line elements for weather satellites http://www.grove.net/~tkelso/NORAD/elements/weather.txt A link to a site for decoding HRPT images directly - http://www.msoft.it/noaa95/ meteosat wefax http://diana.ecs.soton.ac.uk/~pm/Weather/Meteosat/System/metdis.txt gms wefax http://climate.gsfc.nasa.gov/~chesters/text/gms.wefax.schedule.html Sources mentioned: "Weather Satellite Handbook" American Radio Relay League 225 Main St. Newington, CT 06111 (203)-666-1541 User's Guide for Building and Operating Environmental Satellite Receiving Stations July 1997 edition published by NOAA call: Wayne Winston 301-457-5681 Philip Chien, KC4YER Earth News world (in)famous writer, science fiction fan, ham radio operator, all-around nice guy, etc.
