The receiver consumes near
10- milliampere. Inductors L1 and L2
are coiled by an enamel wire in diameter 0.2… 0.25- mm (30…32-
AWG) on the plastic form (it was used a surplus form from an old
receiver) in 5- mm diameter. The inductor is trimmed by a small
ferrite rod to needed band. It is possible to use the inductor
without a trimming rod. Trimmer capacitors C4 and C7 are used
to change the border of the bands. Inductor L1 has 9 turns. Inductor
L2 has 14 turns.
The regenerative receiver
made on one sided PCB plate by sizes 120 x 50- mm. Figure

It is view on the printed lay. Figure 3 shows the view on the PCB at the “mirror view” (view
from the side of the parts). Figure 4 shows PCB with installed parts on it. Figure
