Can Roamio OTA do QAM as well?

Like the title says, can the Roamio OTA tune clear QAM channels as well as the expected ATSC 8-VSB? Maybe a hidden capability? Can someone that has one do check? I found that I can trick the base Roamio into doing both cable and OTA and want to play with something and do some testing, so any help is appreciated.



Thanks in advance! :)
