Yes, indeed. 10 dB S/N in 47 µHz :-) Unbelivable! This indicates that your transmitter and my receiver must be quite accurate ;-)

Since about 9:30, I am radiating a carrier on 8969.98 Hz (GPS controlled) from my home antenna, EMRP approx. 5 uW. I hope to be able to keep it up for a few hours, despite  the presence of minor partial discharges somewhere around the house, as indicated by the noise visible on the LF grabber.

Best 73,
