Hi Peter, all,
Blacksheep seems to be responding
again...
Hmm, 8.925 kHz would be way out of
range of my SpecLab instances. I am currently looking for Opera signals
near 8.97 kHz:
opds-32: 8968.5 - 8971.5 Hz
(Stefan?)
opds-4H: 8969.8 - 8970.2 Hz
(Uwe?)

Hello VLF,
Opera RX on 8KC, 24/7 now.
Also Spectogram available.
The frequency band is 8895 - 8925 Hz, right
?
