typical? or better still can anyone suggest what it might be please?
My gut feeling is that this is radiation from a neighbouring TV (or
even your own??). A growing problem which has restricted my operation
on 136 for some time. Does it only appear during 'tv listening hours'
or all the time, bearing in mind that some sets generate the QRM even
in standby? Have you noticed a neighbour taking delivery of a new set
recently?
I did start a page on my website sometime ago for listing rogue sets,
but have had virtually no input for it - see
