DIY Rotator Controller VK5DJ

Starting the EME, I needed to come up with a serious Azimuth/Elevation rotator. Utilizing my Yaesu 2800 rotator for Azimuth, I built an Elevation rotator based on linear actuator. The DC output for Azimuth position from the Yaesu 2800 was utilized and added a digital elevation encoder producing DC output for the Elevation position. As a controller, I chose to build the VK5DJ controller. The Author, VK5DJ (Jon) was very supportive and provided very affordable PC boards for the project. That worked well and initially was used for 2X6 LFA 6m antennas and currently used for my 4X19 LFA 70 EME Antenna array.
