Hi Laurence,

I wish you would STOP suggesting that Mal is in Lancashire, he's a Yorkshire man & nowt wrong with that. But yes he has a great Rx Tx system.

And of course the "War of the Roses" is over Hi Hi.

73 from a born & bred Lancastrian (that's North West England)

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.

"proper elevated antenna is wasted time except one is content with a few kilometres coverage, and..."

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.
