hello, chris,

thanks, i understand the atmospherics having this effect, but my annoyance is that the bbc, itv channel 4 mux's broadcast at 50kw, are never a problem (so the 50kw power seems to negate the effect of atmospherics?), so my installation is good. recently updated from a 5 element to a 12 element aerial which really improved signal strength.

but occasionally, when there is bad weather / atmospheric events between me and Waltham, the mux's broadcast at 25kw (really pick dave etc.), pixelate and breakup, while the 50kw bbc itv ch4 mux's remain fine.

and then the 10kw mux forces tv, is a problem more frequently.

my questions, being that the power of broadcast seems to be the common denominator. Is why cant the 25kw and 10kw mux's be broadcast at 50kw?, and if this isn't viable on a permanent basis like the bbc and itv mux's are, why cant the power be boosted when atmospheric events occur, to maintain seamless transmission across all programme channels? thanks.
