Hi Nico,

the TDA8275A works very well on the Asus P7131 Dual and I'm about 90 km
away from the transmitter using some old under the roof antennas.

On the Trio, like on the tiger and asus p7131 hybrid the tuner is on
0x61, but on the Trio it is the one used for analog only, not the one
used for digital.

For the dual TDA8275A on the Tevion DVBT-220RF Hartmut recommended the
following with success.

There might be more and just see Hartmut jumped in now,
but anyways.
