Wilton in Wiltshire: Freeview might argue that MENdip is better from an interference point of view than HANnington (although it accepts you are in the Meridian ITV region).
But while ROW is
poor, it
is predicted to be receivable - especially the Vp versions due to less interference from the Continental Hp transmitters. It's also not that far off bearing (166 ROW cf 100 HAN) and if there is a High Pressure 'lift' on Rowridge could come in stronger than usual. But reception is diffracted for both transmitters and pretty low field (according to Wolfbane), so high gain aerial and masthead amp would be normal in the area I'm guessing.
Manual tune and/or choose the correct region should resolve things though. Then consider using
tunefix again should it be necessary?
