Hello!
The capacitances and inductances for the ATU-100 part of the script was taken from .
The cap list is:
- 10pF, 22pF, 47pF, 100pF, 220pF, 470pF, 1000pF
- the caps are connected in parallel, the minimum capacitance equals to 10pF, the maximum capacitance equals to 1869pF.
The inductance list is:
- 0.05?H, 0.1?H, 0.22?H, 0.45?H, 1.0?H, 2.2?H, 4.4?H
- the coils are connected in series, the minimum inductance equals to 0.05?H, the maximum inuctance equals to 8,42?H
So, the tuning is performed with these values:
10pF~
1869pF,
0.05?H~8,42?H.
Please note, the "holes" in the shaded areas (shown here) are because the caps' and inds' values deviate from the ideal row of powers of two, (2^0=1, 2^1=2, 2^2=4, 2^3=8, etc). When one winds the coils - he MUST check the actual inductance he gets, simply following the numbers of turns IS NOT ENOUGH!
The capacitors also should be checked with a meter, their values should be obtained by combining two (or three) lesser ones - giving the correct aggregate capacitance in each individual position.
Warm regards,
Tony
