Congratulations to everyone involved in the State Funeral TV coverage.   Particularly impressive was the sound feed.  A question - how were the sound engineers able to maintain a steady, balanced sound output over a mile-long processional route?  Was there seamless mixing between many sound sources?  Or were there several super-sensitive radio mics and/or sound sensors along the route? To misquote Eric: 'You couldn't see the joins'.  Any views?
