SNR and AGV

[Ojustaboo]

Just fitted my new LNB and before I did so, I made a note of some of the SNR/AGV for various channels to compare them.

What's odd is that in most cases the signal strength has gone up a fair bit, but the signal quality is up on a few and down on a few.

All working 100% fine, just found it a little off that with a lot more signal strength, i was getting less quality on some channels (although was also getting more on others), just curious thats all

A few examples

BBC1 HD     94/73     81/89     (13 less quality, 16 more strength)
BBC2         80/69     81/78
ITV HD       83/69     81/78
CH4 HD      68/39      76/80   (nice improvement of both)
CH5         75/71       77/76
Sky 1       76/54       71/78
Sky News    77/56       66/80
BBC news    86/71       85/76

meant to say I found it a little odd, not a little off

The only way to really test is with a installers meter tbh. I think receivers can be a bit unreliable for readings of this sort. An installers meter is calibrated.
