Grid Square and Distance calculator
Downloads with the VHFLOG update.
Or get SQUARES here.

Software can use my VHF-History.txt file for N.E. US VHF station lookup.
This text file can be used by VHFLOG and N1MM+ loggers.

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.

My loggers have a built-in 6-digit calculator to display the heading/distance.
