What reading level is The Wireless Experimenters Manual Incorporating How to Conduct a Radio Club D book?
To quickly assess the difficulty of the text, read a short excerpt:
89 T"0~6705~ From the curve Fig. 27, K -0. 186 (approx. ).
. ' " x v ' ' 'v, Hence, A 39. 47X X0. 167 = 27, 970 cms.
From the above trial computation we see that less than 12 turns of No. 28 d. S. C. Are required to raise the fundamental wave length of the antenna in Fig. 133 to 200 meters. It is well to have a few extra turns in order to locate the exact point of resonance. The correction term of formula (41) page 57 has not been applied to the problem above. The method outlined in connection ...with the transmitter problem may be followed if this correction factor is to be applied. The results obtained by formula (40) are sufficiently accurate for amateur working.
We must next determine a secondary coil to have inductance of 112. 6 microhenries. We will place 30 turns of No. 30 d. S. C. Wire on a tube 3" in diameter.
From the table Fig. 37, the diameter of No. 30 d. S. C. =0. 015". Hence, length of the coil = 30X0. 015 = 0. 45"X2. 54 = 1. 14 cms.
*A fairly rapid method of calculating the dimensions of a coil for a given inductance is described on pages 286-292 in "Radio Instruments and Measurements.
