Sorry if this is the wrong section, couldn't find one for the 5580

I have a 5580, trying to tune in a Clear QAM J.83B signal, but it never locks.

My parameters are:
Freq: 57MHz
Bandwidth: 6MHz
Symbol Rate: 5361
Modulation: QAM256

I have used different software but cannot get a lock: TBSViewer, TSReader, DVB Dream

I used a AVerMedia AVerTV Volar Hybrid Q, USB TV Tuner and it locked successfully.

What am I missing?

Thank you!
