GJTRACKER ANTENNA TRACKING PROGRAM FOR WINDOWS

The TRACKER program was re-written in October 2008 using Visual Basic 6.0 for use with Windows operating systems. Complete user instructions and associated GJTRACKER files are included in this zip file. GJTRACKER was written to be compatible with WSJT. The current version is 3.0.

SPACE

YAGI ANTENNA ARRAY SPACE/CLEARANCE PLANNING PROGRAM FOR DOS ENVIRONMENTS
(or in a DOS WINDOW under WINDOWS)

SPACE is a simple program that can be used to determine the approximate spatial clearance parameters of an array comprising any number of yagis, stacked vertically and/or horizontally. Front and Rear TURNING RADIUS as well as front and rear CLEARANCE HEIGHT, and minimum GROUND CLEARANCE are calculated as the array is elevated from 0 to 90 degrees. This old program is certainly far from high tech but has proven itself very handy in planning new towers and arrays, and in locating them properly in tight surroundings.

SPACE is also now available as an EXCEL program.
