Mike, Rob, John, Chris...

This is me just being lazy and trying to avoid doing a web search, or
ploughing through Watt's book on VLF Engineering.  Do any of you have a
reference to a *definitive* statement of the transmitter efficiency of
the 60kHz Anthorn transmitter and the 198kHz BBC R4 Droitwich transmitter?
