Picked up VLF receiving again

After years of not being active on VLF receiving, I picked it up again. Received a mail from the SAQ group about the planned Christmas Eve transmission.

So I decided to gave it a try to receive VLF again via the soundcard. Because I had recently installed my new computer on a better location (read soundcard jack at the front) made it much easier to connect my ZS6BKW antenna to it. To my surprise it kinda worked with SDR# 🙂

But from time tot time the signals seemed to fade away. I had no idea why untill I saw that the option to correct the I/Q was on. Turned it off and all seemed normal again.
I’m ready for SAQ (I think)
