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

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

Yes that looks like a good signal at G3XDV, impressive for night-time reception. But hard to measure average S/N on a spectrogram. Currently running the 2-day stack but it's slow with a list length o

Stefan, thanks for the comments. My locator is IO92VT, Welwyn Garden City, just north of London. I was using an "equivalent noise bandwidth" of 44uHz which meant around 9 hours per pixel. If you look
