Request for the GPS interface, beta testing and feedback was provided by
Ken Simmons, K5UHF. Tnx Ken.

Connect a serial cable from your laptop to your GPS unit and KM Rover will show your Latitude
and Longitude as well as the 6-digit grid square you are in. You will be able to tell when you
drive across a boundary into a new 4-digit grid square. Your current 6-digit grid is updated and
displayed automatically as you drive, as is the actual beam heading to a target grid square.

Steve, N3FTI reports that after installing the GPS driver software on the PC, his USB interfaced
GPS works just like a COM port GPS.

Direction to target while mobile:
You can drive and log during the entire contest. The logger tells you where to point the antenna
array. The normal direction heading is displayed in compass format and in text form while you are mobile.
To display the beam heading-to-target, select the [Beam Heading] checkbox. Before using this feature,
your rotor is calibrated to `North` in the driving direction of your rover vehicle. From GPS data, the
actual beam heading relative to your driving heading will be displayed for the target.

Rotor offset:
A manual rotor offset allows using the heading-to-target function without a GPS unit or when your rover
vehicle is parked (and no direction data is available from the GPS). With this feature, you can drive
to a mountaintop and actually know where to point the antenna, without using a compass.

After station setup, get a beacon or distant station`s beam heading from the 6-digit calculator by
entering the station`s 6-digit into the grid field. Peak the antenna on the beacon or station. The
manual offset is the difference between the calculated heading of the target 6-digit and what the rotor
control box reads. After entering the offset, the station will peak at the heading given in the heading
text display, as well as on the compass.

ET to target:
Put the next grid square you are driving to in the `Next` field. Your current grid square is used as the
start grid. The distance and estimated travel time (based on your current driving speed, if not 0) are
displayed while driving to this next grid.

GPS tracking:
You can save GPS Tracking Data to a comma delimited text file. The file can be viewed with NOTEPAD or
opened with Excel or map software. The data filename is the same as your logging file, but with the
extension {.trk}.

KMRover32:
Supports CW/PTT/DVK in NT type OS and all-band BCD encoded data is written to LPT1 to drive a band
switching decoder.
