I have dm520 works perfect on kuband.
Go to cband it picks nothing up, will not scan a a single transponder.
So I got fed up after an hours trying, and turned on the technomate which uses the same lnb, BINGO
the dreambox lit up(uses the same lnb).
Thought it could be a coincidence, so after a few minutes decided to turn the technomate off to see what happens, and straight away the dreambox lost the signal.
Now on ku band they both work as expected, just this weird anomoly on C band
