Why are we bashing the Germans here? Thread creep I know, but let's also have a pop at the Spanish and Italians!
Italian frequencies operating ENE of Nice over the Alps need fixing. Those flying into Nice/Cannes are forced to descend early and as a result require squelch even at FL330. Not realising this many crews just don't hear ATC. Surely the Italian ATC must have recognised this problem so should install relay stations? Same also when trying to remain in contact with ATC flying in the vicinity of Palermo while headed down to Malta. Rome ATC just can't reach anyone below FL370 unless they also are forced to squelch.
As for the Spanish - well I'm sure they are still using microphones designed by Alexander Logie Watt (or was he the lightbulb bloke?) !!
