The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Can anyone confirm tat the COM 7 HD is operating from the ?
I have tried tuning channel 33 as given above but can find . All signal levels are at 8 to 10 on the signal strength and meter for both normal and HD . Tried complete retune but still did not find COM7.

Tuner is Panasonic PVR 9 months old . Can receive with good strength signals for or which have lower channel numbers than for Mendip so don't think that there is a problem with the or PVR. In fact it's a pest, so normally manual tune.

Look forward to a response.
