The Green Heron Rotor Control continues to impress me.
With the formal release of the GH Everyware Program this control really shines! This program allows remote IP based control of multiple Green Heron RT-20 and RT-21 controllers.
Green Heron’s Jeff Ach W2FU demonstrated control of his multi-tower station back in New York state via GH Everyware directly from his Dayton Booth! We watched our commands execute via webcams pointed at the towers. Automatic selection of rotor, tower, polling/voting by rule-sets for multiple users and more!
I’d written about the RT-20 back in As the World Turns – Green Heron RT-20 Rotor Control
The newest RT-21 adds USB connectivity and a new RT-21D model adds a Vacuum Fluorescent Display (VFD) and custom black front panel. Green Heron also builds the K7NV Prop Pitch Systems
Standard Control Box, a customization of the RT-21 to handle the special demands of of a Prop Pitch Motor.
My RT-20 has work flawlessly for a couple years.
