Of course, transmission mode being a negative number is wrong.

of filling StatisticsType with 5, and FullSize with the size of the
payload (this is what happens with sms2270 and firmware 8.1),

SystemType = 0 PartialReception = 0 NumOfLayers = 0

The data under "TransmissionMode" varies according with the signal,
and it is negative. It also matches the value for InBandPwr when
the tuner is on DVB-T (ok, signal doesn't lock, but the power level
should be about the same with the antena fixed, and measured at about
the same time).
So, there's a very high chance that, when StatisticsType is zero, the
signal strength is at the same position as Transmission Mode.
So, discard all other parameters, and provide only signal/rf lock and
signal strength if StatisticsType is 0, for ISDB-T.
