Hi Eddie, I don't think this is my signal. The DFCW shift is 3 mHz, so my upper frequency is 8969.98150 Hz. BTW my FFT and scroll rate settings are the same as used in the typical DFCW-6000 SL instan

PS: Eddie, my experimental CDF VLF grabber is locked to GQD/22.1 kHz. You know the waves sometimes become terminated so the S/N of that reference may be to weak sometimes. So there may be some phase

Hi Eddie, Stefan, this looks interesting. Accounting for your grabber timescale being an hour ahead of UT, your right dash is centered approximately at 6:30 UT. This would indeed coincide with the fi
