File Name: macdoppler-381.hqx (1208 k)
Date: Apr 03, 1999
From: [email protected] 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.

From: Chris Smolinski 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. Shareware: $15 Chris Smolinski

From: Eduardo Foster Subject: MacSatellite 1.6.1 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.

File Name: moon-tool-101.hqx (84 k)
Date: Jul 23, 1997
From: [email protected] 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! - Stefan Anthony

File Name: planet-81.hqx (1260 k)
Date: Nov 05, 2001
From: Lars Gislen 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.

From: [email protected] Subject: Planet Earth 1.0.2 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.
