Hello Hashaem!
good morning!
okay,now iam back,yesterday was my 31.birthday,so i wasnt online!!
now i find time to answer your topic!
one qestions,why do you use to cband lnb for H/v on 68,5 east in cband?
this satelatie sends only linar ,so no dialektrikum plate,inside the cband lnb is neversarly!
if you use 2 cband lnb because of the reason that,you want to reveive circular /linar cband channels in the west,then its okay so,but it takes you a little bit of singal,because,the lnb is not exactly in the right burning point focus of your dish,aproximently one db lost
i am using for 68,5 e a normal vertical 14/18 volt swtiching with 15 kelvin from taiwanese mti company,i dont know strong 68,5 east in your area is,so when you have also very weak signal?
then a single lnb is better for you,other wise,when it is strong enough,you can use your solution,best you post some pictures here,,
i dont own a dm 7025 only the dm 500 normaly on every dreambox is the same,go to lnb settings menu change lof for cband to 5150
save it,on the diseqec port you are using,single lnb configuraiton then save!
on lnb input 1 for e.g
dont use the same lnb input,with difrent lof settings of to difrent satelite,it will be over write the data!
if you have allready done this,and you have still no signal,then 2 other important thinks you must check!
on my dm 500 i notice ,that the R/LZ polarisation is wrong,it is via versa,that means,every other satelite reveiver gets the channel for e.g. on H Linar Polarisation,but the dm 500 turns this ofer,and all stored settings for cband are use les,because the box is searching on the wrong polarity,i dont know the reson for it i only notice it
and the last thing you must check is the option invertion signal on/or off,in kuband you dont need this,in cband on most channels is it nesercarly to swtich it on,reports of dm 7020/7025 or 7000 owners told me,in there firmware,the option for setting to invert signal is mising or not be implemanted in the firmeware,i canto veryfy this coz i dont have 7XX dreamboxes,but if this true,you cant reveive any cband channels with this reveiver!
hope that helps a little bit!
good night!
