I am in the UK with a Nova-t 909 and I can grab both QAM 16 & 64 channels if that helps. Sometimes scanning twice gets me more channels that are missed on the first scan.
I tried many times, I get different numbers of channels for
each scan but never Qam16. With an old driver of the nova-t
I had once 2 Qam16 channels but the others where missing.
