So there is a bit of difference. What I noticed was a lot of noise when for example charging phones while on the radio. That was with the Biltema powerbanks, the old edition. Nice video and walkthrough!

That might have been switching noise and not ripple. All the measurements in this video was done with the 20MHz filter on the scope engaged. Characterising the switching noise it a lot more challenging. I'll try out the "Biltema" power bank on the '705, and if I do detect anything that could be caused by switching noise I may do another video on that as well.

Thanks - fun exercise. Always interesting to get a glimpse of some of the invisible things that influence us whether we like it or not!
