Reading around and what the power levels used to be I wouldn't be surprised to find that they don't run huge amounts power these days, better electronics, more stations around the world, maybe up to 30 kW. MSF is around 17 kW erp and covers the UK and a fair chunk of Europe.
The "in band" Skelton GQD 22.1 kHz that I'm worried about and I've just found a reference(*) to Anthorn GBZ 19.58 kHz (and other references to 19.6 kHz). The bearings to each transmitter are within 15 degrees of each other but due east so won't do any favors for the west, which is a direction we want. Still the north/south should be OK.
(*) http://sidstation.loudet.org/stations-list-en.xhtml A Sudden Ionospheric Disturbances monitoring station. Which also has a design for a loop behind a large framed picture. Has anyone tried two such loops at the corner of two adjacent walls? All the loop designs here are coincident but if I've got the maths right microsecond timing is +/- 300 m. So would a separation of the two loops by a couple of meters actually matter?
