well the mater need to be more patient , as i find out that some boxes has been solved by the update and some not ,
the funny issue is 2 receivers from the same cartoon means same production one is okay and second is not .
anyway the mater has been reported to the right people and a second box who has still the issue has been conected and waiting for new update to comes up soon as i hope .
note : i use 105 cm dish antenna for nielsat and normaly i get 14.00 db but this particular frequency is week i get only 9.80 db .
this freq issue 10873 has been found on almost all hd receivers brands , cuberevo , abcom , humax , and most of chinese brands , thanks for dmm support for beeing the fastest who start to find solutions while others ignoring or not discovered yet their boxes problem .
