Grid Square and Distance calculator

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 pattern.

New: The vhf4k.adi ADIF file has replaced the sixdigit.dat file used for heading/distance lookup from callsign.
The loggers have the 6-digit calculator to display the heading/distance at any time.

Application developed in 1996.
