Depends which box I'm using.
On SS-2 with my Viark Sat 4K I get between 64% to 65% quality with anything towards 63% becoming unstable where the audio starts making those annoying 'drrrrrrrr drrrrrrrr' machgine gun / numatic drill type sounds! Short of upgrading the dish I've been thinking about changing the LNB in attempt to squeeze a drop more juice out (I've got a couple of others I could try but recommendations also welcome) and I've pretty much no rain margin whatsoever.
On my Zgemma H7 I get 51% with 10.25dB and on my Gigablue Quad 4K it's 63%, interestingly, however with never any more than 10.0dB. Any reason why the dB reading would be lower on the Gigablue especially when the % is higher and the tuner is usually more sensitive?
I find the Arena channels on 16e are much easier to come by on e2 servers than SS.
