Heath Model HD/HDW-1780 IntelliRotor


The Heath Model HD/HDW-1780 IntelliRotor allows you to quickly obtain short or long path bearing and distance to any location on the globe and, if you wish, aim your beam toward the corresponding direction in the shortest possible time.

You can rotate your beam manually, or you can enter any of the following to specify a desired location or heading:

  • Country name (or the first few letters)
  • Amateur radio prefix (or partial prefix)
  • Coordinates (latitude and longitude)
  • Grid square or Bearing in degrees.
  • You can also make a selection from one of ten user- defined names.

The IntelliRotor displays the date, day of week, local time (or UTC), and actual bearing.

Additional "windows" also display as much of the following information about the destination as may be determined from the entry:

  • Time*
  • Distance in miles or kilometers*
  • Bearing*
  • Latitude and longitude*
  • Grid square*
  • Country (state or province) name
  • Amateur radio prefix(es)
  • User-defined name.

You can, for example, optimize the IntelliRotor for your particular rotator/beam combination by pressing a few keys. To help prevent jammed brake problems, the IntelliRotor first rotates your beam in a direction that is opposite to the correct direction. It then stops and rotates the beam in the proper direction until it reaches the bearing you desire. The beam rotation slows down prior to reaching the target bearing for better accuracy and to prevent damage near the ends of rotation.

A built-in serial interface allows you to remotely control the intelliRotor from a terminal or computer. You can read the date, time, bearing, and select a new bearing through this interface. In addition, a List function allows you to print a listing, alphabetized by country name, of prefixes, latitudes and longitudes, grid squares, distances, bearings, and offsets from UTC. There is even a Dump function that allows you to make the edited database and setup entries permanent if you have access to an EPROM programmer.

A pop-up utility is included that allows you to completely control your IntelliRotor from a PC-compatible computer. For sight-impaired users, the current bearing may be annunciated in Morse Code. Built-in diagnostics test the program ROM, database ROM, RAM, serial port, LCD, and LEDs. Although the internal database is permanent, you can edit it from the keyboard. Any changes made will remain in effect until you intentionally reset the unit. These and other thoughtful features will make the IntelliRotor a favorite operating accessory for many years.
