Hi Rob
The music is from the radio on the right, the current affairs
discussion is from the radio on the left. I find it easier to place
them when listening through headphones - but then I know where they
were placed :-)

Yes all six mics in each side/channel are wired in parallel. I took
great care to ensure that the phasing of the three capsules added to
each channel was correct, however the front three capsules are 6.5
inches in front of the rear three. This might be causing a problem.

After I have done an outdoors test with the current setup I will try
repositioning the mics as you suggest. Will also try mounting the
front pair of triplets, again angled as you suggest, on the front of
the circular disc which holds the focal point capsules. this will
reduce the reduce the gap between front and rear capsules to 4.5
inches and make a simpler, neater assembly while still allowing the
front triplets to be in front of the plane of the dish's rim.
All good ,interesting fun.
