Anyone had a chance to take a look at the cushcraft AOP-2
oscar array? I have the AOP-1 array but have it down for repairs
and figured I might as well update. From the ads I have seen it look like
a couple more elements on 2mters and a much larger antenna on 440.

Below is the rev 14 Earth-Fixed Greenwich (EFG) State Vector for STS-64.
This vector comes from NASA Goddard Space Flight Center and is provided
courtesy of the DOD C-Band Radar Network.
The data between the dotted lines may be read directly by VEC2TLE to
estimate
the Keplerian Elements for STS-64 in NASA Two-Line (TLE) format. The
VEC2TLE
software is available from a variety of sources including AMSAT-NA and the
NASA Spacelink BBS (205) 895-0028 and may be registered free of charge
for
hobby use.

..........................................................................
The drag values are estimated by VEC2TLE using a 1.0 drag multiplier.
To create a file for use by VEC2TLE, simply write the data between the
dotted lines to a new (text) file. I recommend that the file you save
the data have a .VIF extension (default for VEC2TLE vector input files).
MSDOS/PC software is available for conversion of
OSV to 2 Line Keplerian Elements via ftp to:
oak.oakland.edu:/pub/msdos/hamradio/v2l9331.zip
and the SIMTEL archives.
