[vdr] Weak TNT signal on vdr : how to mesure ?

Hello,

I recently added a NOVA-T500 to my vdrbox. Unfortunately, even if the picture is really nice, I've some freezes because the TNT signal is weak (I am in 50km of the Eiffel Tower...).I ordered a 0.4 dB low noise preamplifier (ULNA 3036 from TGN-Technology) to improve my installation.

Actually, Femon is mesuring only the strengh value (here about 60%), but not the rate of error. I need the two informations to fix my installation.

Do you know any patch for Femon, or any utilities under Linux which can displays all TNT signal informations ?

Thank you. Karim.
