Have two Vu+Duo one with Open PLi 3.0, this show max SNR 93% ,before software update in mid dec it showed 99%.
Today i reflash my second Vu+Duo with Open PLi 3.0 13-01-06, now this box also show max SNR 93% , before it showed 99% with PLi 2.0.

Is anybody more than me having this "problem" ? I did try to google this but no luck.
I have 3 dishes ,all is motorised , i cant belive that all 3 dishes suddenly is out of arc.
2 x Vu+Duo -Open PLi

Laminas OFC-1200 with Channel Master PolarMount, 18" Jaeger, 30W<->75E

The snor is nog based on the max db level...

The frontend.cpp is changed for the Vu Duo.
Check:

Add SNR approximation in dB for VU+Duo:

It will not say the signal is weaker.... only the "scaling" changing it bit...

To have real values, You should check it with db.
For example on Hotbird 13 East 9.5 db is ok For all HD channels (the dream is giving SNR 60 % for that)
8.0 db is ok For all sd channels (the dream is giving SNR 50 % for that)

Astra with 19.2 with 8.0 db is already ok for most HD channels (the dream is giving SNR 50 %)

On the 28,2 East It's already ok with 6 db for HD channels and 4 for SD channels

Sometimes it's very relatif, The % is bassically relatif to the scaling used by the programmer. But db is as far as I know the real value coming from tuner.
