Not sure what sort of TX site you worked at Angrybird but I'm surprised you don't recognise the problems anaprop causes at UHF. You certainly can't go round just turning up the wick without calculating how it will effect the rest of the network, both in this country and across the Channel. Last weeks tropo produced some of the 'best' conditions for a few years for those interested in DXing. Some of the distant signals not normally seen reached incredible strengths last week. I had a number of French TNT multiplexes over riding my semi local Brighton TX. All this has of course been going on for years, everyone will be familiar with the lines and patterning seen on analogue TV but apart from a brief period of pixellation there's little between perfect picture and no picture on DTT. How they expect the proposed SFN to cope with tropo I can't imagine. The DXers amongst us always knew this would happen during tropo, the digital signal is much more susceptible to interference so I'm not surprised those 'in charge' of pushing through DSO didn't want to highlight the problem.
