Thank you Olove for your effort.I buyed this tuner as "tuner from dm500s" and want to construct satfinder with this tuner.I desperately seek this on net.This forum was my last chance.I don´t even know about clones etc.Now ,I can see- it´s big problem to get documentation to this part. I thought i´ts Alps part.Now I don´t even know manufacturer..
Thank you for your effort again..
