Mal – well done on receiving on 9khz but my interest is greater - and a
plot of 1-24Khz or higher would help me and others see the kind of levels
and signal to noise you, on your antennae system, in your part of Lancashire
compares with mine over here so I can move towards that direction. Doesn’t take
but a few mins but I understand if you don’t want to help.
As one that has operated at a VLF commerical tx/rx research station in the
70’s let me tell you on some days there was little to no difference in
transmitted signals – we certainly had days when our ERP’s were less than Stefan
and Ossis’ (!)

ps At this time DHO38 is the weakest Ive seen it over the pole

Laurence there is a BIG difference between radio
amateur transmitted signals and Commercial operators
Regarding LF plots, suffice it to say that if you
read my message you will see that I can copy OE5ODL on 9 Khz in a
qrs 3 window.
and supplied screen shots for
verification.
What is the point sending a 1 - 24 Khz plot also I
use narrow band reception not wideband.

Mal - try telling that to the Russian, US, Chinese Mi$#tary and
Antarctic VLF research stations that - they appear to have other effective
solutions to radiate VLF or lower globally and are certainly not
elevated in some forms :-)
Ill still be very interested in my
request for your wideband VLF plots Mal - even if its just over a couple of
hours from 1Khz to 24KHz say - more if you have it. I just dont know how your
view of VLF is in NE England, near that beautiful county of
Lancashire.

Wrong. They are used by
cavers generally, not just divers, and divers usually only use radio when they
come up for air.
