Giday there Jean-Pierre ..Noise is all part of LF 130 -190khz...generally
if it comes in at evening it lets you know the ionesphere is working down at
that frequency ..IT could be some thousand miles away where it is
generated...lightning storms the arc from a discharge is a very long
radiator its the perfect antennae for low frequency hihi....during daylite
hours noise from lightning travels also a good distance by ground
wave...that big antennae again...some days smooth noise seems to come from
ionesphere...why i dont no...perhaps its haarp harping about hi...73s from
nucular free New-Zealand....kia-ora

Subject: LF: [137] QRM !
Hello all on LF ,
I am very anxious because since yesterday I am QRM on 137 Khz ,
the noise floor went up of 20 dB ! the last night the grabber was
disturbed and XGJ was just visible !!! This evening that seems better,
but not returned at the normal level. I hope that it is only passage
because that is likely to put in danger my activity LF !
