Re: LF: Russian Alphas not QRT but QRP ?

[David Hine <evad_hine@yahoo.co.uk>]

Hi, I do transmitting on ELF occasionally on a frequency of 1.6 Hz using a 'Tesla' antenna, giving a global range (screenshot example from Kiruna, Sweden, attached). It is likely to be a 'QSB' fade out, and at ELF, these can last for many days. I have noticed this often on my transmitted ELF signals, with a 2 week QSB period being the average.

Kind regards, David

I think the reason is that currently only the far east station is operating. See for example the WWLN spectrogram from Yakutsk, showing only one dash on each frequency:

Hi VLF

Looks like at least the 11.904KHz Alpha is still leaving very weak traces in the grabbers

Just like still operating but with much less ERP ?
