I think you will find that Yesterday, Film 4, VIVA and a few others ate breaking up
to the same degree as ITV4 because they share the same multiplex.

Not too long till the end of August, and your problems will probably resolve themselves.

Same problem exists on Hannington.

OK here (Hatch Warren), stable as a rock on that mux.

The non-PSB muxes on Ridge Hill are supposed to be half the power of the
PSBs but anyone would think they're 20dB down looking at what I'm
getting here. This is post DSO, so it looks like I'm going to have to
live with it. Most of the time they're rock solid though and there's
only very rare pixillation that's hardly noticible.

ScanChannelsBDA on the PC shows the PSBs at around 95% quality and the
non-PSBs at around 75%. I'm guessing 70% is probably the "brick wall".

Strange - I'm getting this at 5 different locations in Kempshott Park, and they
have line of sight to Hannington.

Maybe it's another "notch attenuation" issue? The interstitial analogue signals are
too strong.

Yes, it could well be ITV analogue on Ch 42 splashing over onto the mux, (Ch
41). I get a 14dB-16dB difference between the DTT muxes and the analogues on
39/42/45. It's also not impossible, because of your elevated position you're
suffering co-channel interference on Ch 41. Wenvoe DTT uses it at high power,
there's been a lot of lift activity recently. That often visits round here
during such periods !

You're line of sight to the mast up there, I'm lower down, close to the
Kempshott roundabout, with the transmitter behind trees.
