Group Frequency Selection
The spectrum of 9 to 200 meters is divided into five groups; 9-16; 16-28; 28-49; 49.92; and 92-315. The range of each group is covered by an individual oscillator inductance and input inductance. Each inductance scientifically wound on shallow threaded forms of high dielectric and calibrated accurately for frequency register. The live leads from these coils are not brought down inside the form, causing a short circuiting effect, but directly away from the outside of the winding by short lead (% " to 14 ")
