Dave,
I am curious how you soldered (braized?) the brass shim. I've been thinking about making my own shields (not for my nano) but am a bit intimidated by my lack of experience with brass.
Thanks,
Dave L

Hi just spent a UK windy afternoon confined to my radio 'shack' , so decided
to upgrade the screening on my 'basic' clone nanoVNA to see if the INPUT
'noise' could be reduced.
I made the screens out of some 'shim' brass foil and formed them round some
srbp (Tufnol) formers THAT I made first.
I am pleased with the improvement that just a couple of hours 'metal bashing'
has produced.
Hopefully this will inspire others to have a go?
Dave
