Hi Freddie and Stephen,
Trouble with Auntie, was the 'suits' didn't listen, to the what their own engineers said.
A good example was in the early days of DAB, where advice was ignored

Spot on Freddie, with "Pirates taught the experts a thing or two"...
Here in the Midlands the Mi-Amigo on 1187 was stronger than the "Light Programme" as it was called, on 1214

When Radio 1 started, as an alternative to the pirates, we had The BBC Fiasco of several high power sites,
All on the same 1214 channel, so between sites, they jammed themselves, It gave a weird hollow Phasing type distortion,
What BBC techie, or radio authority, came up with that daft idea?
...And guess who sorted it out, Offshore Engineer Peter Chicago,
with the Alternate use of 1053/1089 so that adjacent sites, didn't use the same channel

and Stephen,
The BBC World Service originally was from Crowborough (near Tunbridge Wells) Was Over 20 Miles from the sea!
Only when the failed Radar system at Orfordness Ended, did they move it to there
