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 From: Markus Vester <[email protected]> To: [email protected] Sent: Friday, 9 February 2018, 20:32 Subject: Re: LF: Russian Alphas not QRT but QRP ? 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:

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 ?
