I'm too modest to mention that the February issue of "Satellite Times"
includes an excellent article on inexpensive weather satellite APT
reception by myself, ....

but not too modest to include the portion of the article which was
accidentally left out in the page layout, most importantly including web
pages and other resources.  Note that the NOAA book is *FREE* for anybody
who requests a copy.

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
"wxsat-request@ssg.com" with blank subject line and "subscribe your name"
as the message (where "your name" is your actual name).
