I like measuring things in the lab and doing the calculations, so we can
avoid blowing things up, wasted time and disappointment, but I also like to
put the thing into practice and do relevant measurements in situ.

I'm building yet another current meter (others have grown legs and wondered
off somewhere) to "measure" braid current with various chokes.  I've ordered
some of those nice obrounds from Farnell.

One thing that interests me is that we never used chokes and baluns "in the
old days"  circa 50s and 60s - how did we live without them?  Not many beams
around my way in those days; I'm more interested in keeping noise out of the
receiver.
