[amsat-bb] RF noise from a passing-by BMW i3

[Michelle Thompson]

We have a Nissan Leaf. Now that you describe this, I think I've seen the
same at home!

I have several friends with Teslas, and can get an i3 to characterize. If
you're interested write me off list and we can get some data, if you like.
