Getting Started with Antenna Rotator Control

If your antenna's rotator controller is an AlfaSpid, Green Heron, Heath, Hygain, Idiom, M-Squared, Prosistel, SARTek, TIC, TrackBox, or Yaesu unit that can be controlled by a PC, then DXView will enable you to rotate your antenna to a selected location's short path or long path heading with a single mouse click.

To set this up,

  1. Connect your rotator controller to a serial port on your PC as described in the rotator controller's documentation; this likely requires an RS232 cable

  2. run DXView, and click the Main window's Config button to open the DXView Configuration window

  3. in the DXView Configuration window, select the Rotator Control tab

    1. in the Serial Port Interface panel,

      1. select the PC serial Port to which your rotator controller is connected

      2. set the Speed, Word Length, Stop Bits, and Parity to match the settings shown in your rotator controller's documentation

    2. in the Model panel, check the box designating your rotator controller model

    3. in the Directive Acceptance by Band panel, check all boxes

    4. check the Enabled box at the upper-left of the tab

To verify correct operation,

  1. type a DX callsign into the Search panel on DXView's Main window, and strike the Enter key or click the Go button; the Heading panel will be updated to display short and long path headings from your QTH to this location

  2. click the Heading panel's SP button; your antenna should rotate to the short path heading

  3. click the Heading panel's LP button; your antenna should rotate to the long path heading

You can also specify a heading by

* clicking a location on DXView's world map

* selecting a DXCC entity using the prefix or entity selectors on DXView's Main window

* typing a grid square into the grid box on DXView's Main window and then striking the Enter key

* typing a latitude (e.g. 37 30' 7" N) into the latitude box on DXView's Main window and then striking the Enter key

* typing a latitude (e.g. 123 10' 13" W) into the longitude box on DXView's Main window and then striking the Enter key

* typing a an IOTA tag in the IOTA box on DXView's Main window and then striking the Enter key

* typing an azimuth into the short or long boxes on DXView's Main window

After specifying a heading, initiate rotation by clicking the SP or LP buttons for short path or long path respectively.

DXView displays the most recent SP or LP command sent to the rotator immediately above the SP and LP buttons:

In the above image, the last command sent to the rotator was "158 degrees, short path"; unless you subsequently djusted your rotator's heading via its controller's front panel, this should display the rotator's current heading.

Antenna Presets

Dragging the right border of DXView's Main window to the right will expose two columns of Antenna Preset buttons:

To define one or more presets, depress the Ctrl key while clicking any preset button. DXView's Antenna Presets window will appear, enabling you to specify each preset Heading and a discriptive Caption to appear on its button.

Dragging the right border of DXView's Main window to the left will hide the Antenna Presets.

Rotator-specific Information

Managing an Antenna Mounted with an Offset

If you have an antenna on your tower that is mounted with an offset of X degrees with respect to the other antennas on that tower,

  1. In the Alignment panel on the Configuration window's Rotator Control tab,

    1. set the Ant1 rotator offset to 0

    2. set the Ant2 rotator offset to X (where X is an integer greater than 0 and less than 360 representing the offset between Antenna #1 and Antenna #2).

  2. Double-clicking the Main window's Heading panel will toggle the actual heading (displayed immediately above the SP button) between Antenna #1 and Antenna #2.
