I don't know what "acu" refers to, and assume that "usails" refers to USALS, but I think it's pretty unlikely. USALS involves sending a goto-X angle to the motor, which is then number of degrees that a H-H mount turns on the polar axis. Most people with
C-band dishes don't have H-H mounts, and for those that do have H-H mounts (I do), there is no guarantee that the # counts per degree will be the same from one mount to another. For those with an
actuator, different actuator brands have different # counts per inches extension, plus the geometry of how the actuator attaches will be different for each dish, plus the extension of the actuator isn't linear with respect to the degrees of movement of the dish on the polar axis.
Bottom line, while it is possible, if they knew your setup, the answer is no, it isn't realistically possible to have USALS work on an actuator, and wouldn't be worth their investment to put it in the
VBOX for the very few BUD owners with H-H. Plus, even if they did, you'd have to manually calibrate it.
