Between 08:47 and 13:55, I have transmitted a DFCW-3600 "NM" on 8970 Hz plus
3.02 / 1.02 mHz . Samplerate was locked to DHO, EMRP between 5 and 10 uW from
home.
This is clearly neither of Roger's traces. But it's visible in the "6000" panel
at DK7FC, and the twin peaks have apparently been picked up by Paul Nicholson
along with Uwe:

Subject: LF: Re: Other VLF transmissions around 8.97kHz in the last 24hrs?
The first mystery signal was more like 3-4dB S/N and not 24dB (slip of the
keys).
...
Uwe DJ8WX has been good, very stable, copy all day here in the UK on
8.970022kHz
at up to 20dB S/N in 423uHz BW.
When adjusting the SL screen and looking on my grabber just now there are two
other signals there which may, or may not, be someone else:
8.970045kHz very stable signal from around 1300 3.3.11 until around 0700 4.3.11
(about 24dB S/N in 423uHz BW)
8.97008-8.97010kHz a signal that moves around about 20mHz between around 1300
3.3.11 until around 0700 4.3.11 (about 4-5dB S/N in 423uHz BW)
Can anyone confirm if either of these other signals are from someone else
please? Ossi or Gerhard maybe?
73s
