Signal doesn't seem to be locking on Dialog Package(Ku Band) in my DM 7020 when I do a Automatic transponder search.
Manually inputting the frequencies give the same result.
Some Dish TV channels are getting locked when frequencies are manually put-not all but some.
On C Band Multichoice signal is getting locked.

All these channels are getting locked when I connect the DM 600.

That shows the antenna alignment and LNB configuration cant be the culprit (as I have carefully put the same LNB configurations)

Any clue ?
