I think Emley took Waltham for its RBS source?

I think the network distribution from Manchester went SHF via Windy Hill BT tower to BBC Leeds and back to Windy Hill before going to Emley and Belmont. It's possible that the weather affected one of the dishes so the Leeds round trip was patched out at Windy Hill and Manchester CTA sent the NW dirty feed to Leeds instead of the sustaining feed?
