I've been using my Ferguson Ariva 100 for over a year now & for FTA it does very well.
Mostly for FTA C-band but also for the FTA Ku band both with motorized dishes: A 7.5ft Perfect 10 C-band & a 36" WSI Ku band with a DG380 motor.
Only two files can be used for the Openbox S9: the TS tool & the Ariva Editor.
Both are available at ferguson.de just for the searching. Be sure to turn on your translator.
