OK its up now Stefan.

Live Windows = Wide, ZEVS and Alternate View for 60Hz US DX.

I am not sure what ZEVS is like here lately I have been away enjoying our UK Indian summer for 2 weeks. It looks as though the 80Hz signal is good, no idea where that originates from.

Fairly heavy rain today falling now.

Hi VLF,

Could someone of those who are able to monitor ZEVS run a temporary grabber so one (i) can see if it is active? That would be very helpful.

I've done some changes on my circuit but now the band looks so clear that i'm asking myselfe if the FET is damaged again, this morning. And i didn't see ZEVS. But maybe it was OFF and the noise is really so low... :-)
