I have completed the Arduino-based rotator computer interface and controller project or at least gotten the code and functionality stable and to the point where I’m satisfied with it. The unit emulates the Yaesu controller command set and works with Ham Radio Deluxe. I’ve tested the unit with a Yaesu G-1000DXA rotator. While the code has AZ/EL rotator support, I do not have an AZ/EL rotator to fully test the elevation functionality yet. This summer I hope to assemble a satellite antenna setup complete with an AZ/EL rotator using this interface.
If anyone is able to test with an AZ/EL rotator, or if anyone wants to attempt to interface this to another brand rotator, please let me know as I would be glad to develop the code.
