Portable transistor radio "Road".
Portable radio receivers and radios on p / p.DomesticThe portable transistor radio "Dorozhniy" has been produced by the Moscow plant "Krasny Oktyabr" since the IV-quarter of 1956. The radio receiver "Dorozhniy" was developed at IRPA in 1955. It is assembled according to a superheterodyne circuit on eight transistors and operates in the range of long (LW) - 750 ... 2000 meters and medium (CB) -185 ... 550 meters of waves. Reception of radio stations in stationary conditions is carried out on an external antenna, in a portable mode for a small section (1.5 ... 2.5 m) of wire. Powered by two KBS-L batteries, with a total voltage of 9 volts. Sensitivity with an external antenna is about 200 μV on both ranges, with a piece of wire 2 meters long about 2 ... 3 mV / m. Selectivity (rms selectivity) - 12 ... 14 dB. Rated output power - 150 mW. The range of reproducible sound frequencies is 150 ... 4000 Hz.
