Worked quite well second time. (the post formatting I mean).

The amp will have two stages with a variable attenuator between them. It
sounds as if one stage is not working.

Connecting two aerials and achieving a correct phase relationship is
impossible in a loft, because the surroundings affect the behaviour of each
aerial so much.

My dear Basil, I'd love to show you how it is possible to get two aerial
exactly in phase, then move the nulls around by altering the distance
between them. When I do it it's sheer poetry. Have you seen Fred Astaire
dance? Well that's me on a big roof with a stacked or bayed array. When it's
windy I can even detect Emley Moor's sway. At this moment I'm listening to
the London Symphony Orchestra working their way through a few Beethoven
Concertos. Those boys have got nothing on me when I've got a pair of TC18s
to play with.
