Yuri`s point is proved. Look at Fig 6. The picture is worth a thousand
words.

Yes, but then on page 16-7 Fig 10 they show that current across the coil is
constant, which situation I analyze in my article at www.K3BU.us as an error
being perpetuated since 1955 by Belrose.

W8JI used this picture to "see, it is constant" :-)

I wonder if 20th edition has the same stuff. I haven't got new book yet.
