c24 Technical reflexions about constructing coils Coils (under
work): where L (ÁH) = inductance. d= diameter in cm, l =length
in cm, N = turns. *) Note the link should have magnetical
coupling to the coil, and should be placed at the bottom end of
The right picture shows a coil with similar socket as for Tech
TE15 dip-meter. Once popular slug-tuned coil, but the rather
long screw makes it very little practical to use! American pre-
war ready-wound coil, bought at an auction in Oslo last autumn.
