Subject: MacDoppler v3.8.1
* MacDoppler will read in the Keplerian elements (in either format),
calculate the position and relative velocity of the Satellite you are
tracking and automatically adjust the Doppler shift on both transmit and
receive as well as pointing your antennas.
* Without registering, the application will run for 30 minutes and track
the satellite(s) you choose and display the proper Doppler corrected
frequencies that can be entered manually in any rig. When registered with
AMSAT ($50.00 US) MacDoppler will connect to your radio and rotor
controller through any two serial ports and make the corrections for you
once a second.
* A Track List Dialog allows you to track up to 8 satellites
automatically.
* MacDoppler features full predictive dead spot crossing so that a pass
is never interrupted by the beam heading passing a southern dead spot.
* A slider control allows you to sweep the VFO through the transponder
range while the transmit frequency tracks the receive frequency. When you
hear something interesting, MacDoppler continues to track the frequency
through the Doppler changes.
Requirements
MacDoppler requires an Apple Macintosh II or faster (some features only
supported on Power PC), 2.0 to 4.0 MB of RAM (over and above the OS),
System 7.6.1 or later (MacOS 8 required for the Frequency Slider to
work). The Application is FAT Binary, an FPU version is also available
for 68k Machines with a Floating Point Unit.

Subject: Mac Grayliner 2.2.0
Mac Grayliner displays a map of the entire Earth, showing day, night, and
more importantly, the terminator between day and night. Studies have shown
that
enhanced radio propagation occurs between two points which are both on the
day/night terminator.
Now with version 2.1.1, the locations of active NCDXF/IARU beacons can be
displayed in real time, along with the beacon callsign, country, and
location. This should be helpful for identifying DX openings.
Mac Grayliner requires a Mac with a color display.

Hello, I've uploaded the new MacSatellite (version 1.6.1)
This is a PPC - Classic version.
There's a read me file with the application that explain how to use it.

Subject: Moon Tool 1.0.1
I recently found to my surprise that the Info-Mac archive doesn't have a
copy of this wonderful program.
Please note that Richard Knuckey ([email protected] the
author of Moon Tool. I am merely submitting it to the archive.
A description of Moon Tool, from its About Box:
"This application displays the moon in its current phase along with
detailed information on the Moons phase cycle, subtends and distance
from the Earth. To display this information, your Macintosh needs to
have its time zone information set up correctly. This can be done using
the Map Control Panel."
Moon Tool is freeware. Enjoy!

Subject: Planet 8.1
PLANET 8.1 is an application in which your Macintosh computes the
coordinates of the planets visible to the naked eye (Mercury, Venus, Mars,
Jupiter and Saturn), the sun and the moon. The coordinates are given in
different coordinate systems: the geocentric ecliptic and also the
equatorial and horizontal systems of the observer. Further you will see
the magnitude of the planets and the phase of the moon and also sidereal
time, mean solar time and the equation of time.
When a solar or lunar eclipse is possible you can also investigate the
eclipse from any place on earth. You can study heliacal risings and
settings of planets and stars and also conjunctions, planetary stations and
occultations. A special option in the program allows you to check the
visibility of the new and old moon crescent.Finally you can study the
transits of Mercury and Venus.
Included with PLANET is a small helper application, Mini Star Catalog,
containing a list of 410 bright and important stars. It is possible to
choose any star from the catalog and transfer it (one at a time) to PLANET
by drag and drop. Once the star is inside PLANET it will displayed by
coordinates updated for current precession and proper motion. Also it is
possible to study the heliacal rise and set of the star.
The program is freeware.

Planet Earth - have you ever wanted to see the Earth from space? Now you can see
what it looks like right on your desktop. Planet Earth displays a realtime
3-dimensional model of the Earth with the current cloud information downloaded
directly over the internet. Night and day shadows are updated continuously and
you can rotate it to view any spot on the Earth.
