Fig. 24. This is the circuit of the Paragon RA -10. A "leading
coil" is inserted in both the primary and secondary circuits so
that higher wave -lengths can be reached. These coils are cut in
and out of the circuit by switch "SW".
Fig. 25. The hook-up of the Aerolia Sr. Coils A, B, C and D
are all wound on the same tube while coils E and F are wound
on smaller tubes and rotate within the others. When the aerial
switch is on contact "S" shorter waves can be received than when
on contact "L".

Fig. 26. A very good regenerative receiver with but two
controls, i. e., the variometer and the variable condenser. Coils
"P" and "8" are wound on the same tube with about 1/3 in. between
them. The variometer should be placed at the end of this
tube. Coil "P" should be "stagger" wound.
Fig. 27. Another circuit with but two controls. This is an
adaptation of the Colpitta oscillator circuit and has proven to be a
very sensitive regenerative receiver.
