Re: VLF: Night-transmission on 8270.1 Hz

[DK7FC <selberdenken@posteo.de>]

Hi Paul,

Many thanks. The signal is slighty smaller , maybe just as smaller as my 
output power dropped. Very nice.
How many character could have been carried in these 130 minutes if an 
EbNaut message would have been transmitted? It is hard to estimate the 
carrier S/N from the plot.
Hard to belive that my recent 2970 Hz signal didn't make the same path 
with a detectable SNR. Maybe this upper ULF region is much more complex 
than we think...
Oh BTW there has been a carrier transmission on Friday morning, 
2019-01-18_09:42,2+h on 1970.01 Hz. I reached almost 3 A antenna 
current. But no signal at DL0AO or DL4YHF... Some months back it was no 
problem to detect the signal on my tree, with much lower power and 
higher QRN levels...
73, Stefan
