Just to let others know that the RotorCard SDX works with MacLoggerDX for rotor control of the Yaesu SDX series rotors. This card is sold by Idiom Press and is very inexpensive especially compared to Yaesu's option. They also make a card for the Yaesu DXA series. I have no affiliation with Idiom Press just passing on what I have discovered. Pete WK8S
