Grid Square and Distance calculator
Your compass is no longer needed! Align your rotor control indicator using six digit grid squares.
Enter the six-digit for your favorite beacons into SQUARES. Then peak your antenna on a
beacon and adjust your rotor indicator to the heading indicated in SQUARES. Peak your
antenna on another beacon in the opposite direction to verify the rotor controller`s
linearity. Do this procedure on the microwave bands to check for skewing of the antenna
Old: The sixdigit.dat file was used by my loggers for heading/distance lookup from callsign.
New: The larger file vhf4k.adi is now used for look-up.
The loggers have the 6-digit calculator to display the heading/distance at any time.
GenLog users: SQUARES comes with VHFLOG, but you can
download it here. Run the installer and extract the
files to your logging folder and make a shortcut.
