Counting from the blocking capacitor end, the plate coil is tapped at 4
turns for 10 meters; 7.5 turns for 15 meters; 10.5 turns for 20 meters; 14
turns for 40 meters; and 24 turns for 80 meters. All of the figures
include the 4 turn coil made from 3/8 strap.
NOTE: Strapping should then be run to the band-switch terminals which do
not progress in consecutive order and arranged to provide the shortest
possible lead length.
