Description: 
The HD-1780 was designed by Heath for Telex as an OEM product. The factory assembled versions were sold with the TailTwister and other Telex (Later Hy-Gain and CDE) rotators and distributed through Telex's dealer network. Manufactured 1990-94.  It was also available in kit form from Heathkit by mail order. This unit is a one owner factory assembled unit sold by AES in 1990 with a T2X TailTwister rotator (T2X not included). The HD-1780 is compatible with the popular Ham-M (series 3,4,5 and 6), Ham-II, Ham-III, Ham-IV, T2X, CDE, TR-44, CD-45 (series 2), HDR-300, and M2. Uses 8 wire control cables. 

The QWERTY keyboard lets you swing the antenna based on entry of callsign prefix, grid square, latitude and longitude, bearing in degrees, or first few letters of the country, or manually. The unit has a ROM database of 400 countries and allows you to add 10 headings of your own. The HD-1780 also can be connected to your PC (DB-9) (with supplied software on floppy disk) and can report headings in 20 wpm morse for visually impaired users. Features include motor pulsing, automatic brakes, and initial back-rotation to protect brakes from locking due to wind loading. 

The IntelliRotor can be controlled remotely by a PC or other serial terminals or interfaces. This makes the IntelliRotor desirable for Remote Base Operation. Built in diagnostics test ROMs, RAM, serial port, LCD, and LEDs.

To help prevent jammed brake problems the IntelliRotor first rotates the beam in the opposite direction, then stops and rotates in the desired direction and slows down as it approches the correct heading. This method also prevents damage at end of rotation limits.
