Hello Hans,

problems receiving lf are normally due to high local QRM levels and

you can try an active antenna on a noise free spot.It's all tryal and
error...
Beware of broadband rx antenna's when their are broadcast stations nearby=

The rx I am using is a hongarian REV-251M with a broadband active whip 50=
 cm
long.The only inputfilter in this setup is a rejection filter at 675 KHz
between antenna and receiver to prevent overloading of the
receiver.Unfiltered Arrow classic rock at 675 KHz gives an output of
400mV!TX antenna is 9 m vertical with 20m topload.

Hope to work you soon Hans
