i don't have much experience with lf, but i see a big deterioration of the 
noise floor at vlf. in december 2006 i could receive SAQ from my balcony 
using a loop by ear. in december 2007 i could barely receive it. in 2008 
it was all lost in the noise. the same goes for other antennas that i use.
BTW it is incredible that nowadays people in north america are using 
sophisticated receive setups with FFT to barely receive SAQ, and just 90 
years ago they used crude receivers for a 24h/7 telecomunications service 
between the continents without problems. the noise floor is way higher 
now.
