I've made good progress on finding the sequence needed to initialize the MT352. I'm not done quite yet, so I probably won't have something for test until next weekend. I think the MPC718 variants might use at least 3 different DVB-T demodulators: Mitel/Zarlink MT352, Zarlink ZL10353, or some DiBcom chip supported by one of the dib7000x drivers. It looks like you might have an older card. > > XCeive 3028 Hybrid Tuner + analog demodulator > > OK. Please confirm that this is the XC3028 and not the XC3028L. Given that your board uses a MT352, which is rather old, I'd expect the board doesn't use the XC3028L - low power tuner.

If not 0, it will likely be a low number like 1, 2, 3, ...
