109 RADIO HOOK-UPS
Fig. SI
Fig. 59. We have hers a loop receiver with two stages of
tuned radio frequency amplification. This type of amplifier is very
efficient The coils L and L-1 will have the same values and may
be Honeycomb coils. However, 35 turns of wire on a 3 in. tube is
the approximate value for broadcast wave lengths.

Fig. 80. With thin combination It is possible to cover a coneiderable
range and obtaia fair volume. It consists of one stage
of tuned impedance radio frequency amplification and one stage of
audio frequency amplification, in conjunction with a single circuit
receiver. Cell L is approximately 35 tarns of wire on a 3 in. tube,
or a Honeycomb coil of a similar size.
