Hello Mike, |
This is a very good result!
But it is a bit difficult to read the SNR. The relatively high SNR
would allow you to run a faster spectrogram. What is the current one,
maybe 30 uHz (value of "width of one FFT bin")?. If so, you could try
about 60 uHz and a 2 times faster scroll rate. This will lower the SNR
by 3 dB but you can see more pixels and see how the signal level fades
during the night time. You can also run 2 SpecLab instances
simultaneously and can decide later which of the two spectrograms are
It appears to me that the QRN is lower during the last few days, which
also helps us of course.
What was your locator? Something in IO92, right?
There have been a few more requests for another carrier this night, so
i will just continue to transmit that night. Just follow the grabber...
Due to the lower QRN, Paul may decode the 100 character message after 3
(or even 2) days already, so i would consider to run a 24 hours or 36
hours carrier before i actually move to 6.47 kHz with the new coil...

Thanks to Stefan for transmitting a carrier overnight. This is very
useful for those of us who are not quite ready to decode EbNaut
transmissions but want to optimise our VLF reception.
My screenshot is attached.
