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. -- Eric Roskos (roskos@CS.IDA.ORG or Roskos@DOCKMASTER.NCSC.MIL) -- Eric Roskos (roskos@CS.IDA.ORG or Roskos@DOCKMASTER.NCSC.MIL)
