[poliv123]

Hello everybody!!!! Good day!!!
i need your opinion and help!
i have vu duo2 and edision osmini dvb s2 receivers
i noticed that edision osmini has more sensitive tuner-better tunner than vuduo2.one costs 90e and the vu is more more expensive.the edision has better db's signal espesially in bad weather etc...
I have to say that i have tested the 2 receivers in same setup(motor usals-same lnb-same cables)

There is no “standard” for signal strength or signal to noise ratio (SNR) on these type of boxes so comparing the values seen on a box from one manufacturer with the values reported by another manufacturer is often like comparing apples with oranges. The important parameter to check is the BER (Bit Error Error Rate) which should ideally be zero.

One box may have more sensitive tuners than another but looking at the signal strengths reported by the box is seldom a reliable way of establishing this.

Is the picture breaking up on either box?
When you say the same set-up have you swapped the boxes around?
