Just a further update 🙂
I'm guessing this is a banded profile too !
Been like this for a few days now. Seems to have bottomed out at this !
The Bt support guy I've been dealing with is back tomorrow.
Hopefully will sort a visit after speaking to him.
Seems things have improved without any intervention 🙂
Is this still a banded profile ??
I also notice the noise margin has dropped !
