I am getting a cog wheel effect on ITV with bent verticals, also with “pulling” to the left, yet on BBC it is perfect.-J. Malpass (Walsall). Since the BBC picture is unaffected we feel that the trouble lies either in the ITV aerial system or diplexer. It is possible that the aerial signal has weakened due to a fault here. Another possibility is misalignment of the tuner, for in
this event the sound would be weak and the fine
tuner would have to be turned fully one way
or the other far reception.
