[sci.space] Hurricane Gabrielle GIF pictures from GEOS

roskos@IDA.ORG (Eric Roskos) (09/13/89)

Phil forwarded to me a question someone asked about how these pictures
were produced.  Unfortunately the posting in which the question appeared
has not arrived here, so I will follow up to the original posting.

Note, incidentally, that the pictures are not from GEOS, they are
primarily from the NOAA TIROS-N satellites.

The equipment used to produce these pictures is as follows:

	- Dressler ARA-800 active antenna
	- Kenwood R-5000 with internal VC-20 VHF converter
	- A&A Engineering WEFAX demodulators
	- PC/AT clone
	- My own software to produce the raw data
	- FBM to produce the GIF images

The R-5000 unfortunately does not have adequate bandwidth for the
satellite pictures, which is the reason for the snow in some of the
whitest and blackest portions of the picture.
