Hi,

i can confirm that this is (at least with my 2.1 TT board) correct.
when the driver gets stuck (happens sometimes after extensively OSD use
and heavy channel switching mixed) the signal strength and snr values
are still "normal" (i.e. don't change)
If a real signal loss happens (rain, trees, etc.) the ss and snr are
going down.
