Many thanks for your response - there is obviously nothing new under the sun !
Do you remember anything as to how the output from the dishes was combined - if whatever was done worked on analogue signals there is no reason why it should not work on the present digital signal.
So far as implimenting the idea is concerned I have found that there is no problem getting flexible waveguides to convey the 10.7 Ghz signal between the dishes but the only adjustable delay line system I have found so far is a digital box costing about $2000.
