Note: Wire broadcasting center (Figure 1) had a directional

antenna (item 1), as usual, at LW, MW and SW it is

a magnetic loop antenna, a high-quality receiver (item 2)

for a proper band, and a high powerful audio amplifier (item 3). Amplified audio signal is distributed through wire lines (item 4) to consumers living in to hundreds and ever thousands cities building (item 5). Consumers must have a simple loud speaker to be hearing the broadcasting. Wire broadcasting was widely used in the USSR since 30s till the end of the 20 century. Wire broadcasting has the profit that consumer

must have only a simple loud speaker not a costly receiver.

However, a consumer has not a choice, and must be hearing only the distributed through the wire broadcasting. Also wire broadcasting was widely used at Germany since 1935

since 1945. As usual, the directional antenna and high-quality

receiver were situated in rural, where radio interferences

have small level, a high powerful audio amplifier can

be as in rural as in the city. (I. G.)
