I have to write again as nobody seems to have a solution of this problem. Comparing to many other satellite receivers we have had during the last 20 years, I am surprise that this AMC 570 cannot receive all the strong channels on i.e. ASTRA 1 (19,6°), Thor (1°) as well as ASTRA 2 (26,2°).
It must be a software problem. Thanks for any information when this will be solved.
