I usually used rotor control itself. It can not computer control and no used external control.
Therefore sometimes wrong direction by my antenna direction.
Normally I operate on HF band. So it not critical direction by contact place. About 10 degrees different, it no problem.
However, if EME operation use. It is big problem by this matter. It need correct direction. So I looking for extrenal robot controler.
I looking for that by internet. I just found that. That is ARS-USB. It made EA4TX, as same as Arduino systems.
I am interested in this controler. So just posted Moon net ML.
Who is use?
I will waiting answer for everyone.
