if the trace is still noisy, whether or not you activate the CW filter...
Bonjour Yves,
The trace is as noisy with or without CW-filter. I already wondered what this CW button is doing at all :-)
When its on, the LED behind is not as bright as the others, perhaps there's a reason.
Thanks for the details, will check circuit diagram and inside!
cheers
Martin
