Dear Robert,
thanks for your kind answer. Can you please give me reference values for
SNR and Bit Error? I got 4.8 dB and 2000-3000 for them, depending on the
channels. Actually, SNR seems to be constant, I mean it's alway 4.8 dB,
while BE changes instead.
Also, my dish works perfectly fine with my stand alone decoder (I have
two cables from one dish), so I guess it's not its fault.
Best regards.
