The stationary transistor radio Rodina-60M1 since 1961 produced the Chelyabinsk plant of the radio-technical industry. Radio "Homeland-60" after a small number of mass-produced vehicles due to design flaws in 1961 was upgraded to the radio Rod'in-60M1. The radio receiver is a desktop transistor superheterodyne of the 2nd class, operating in the bands of LW, MW, and HF (3 subbands) waves. Power supply at the receiver is universal; from six Saturn batteries or from the mains through the built-in rectifier. The retail price of the radio is 78 rubles 75 kopecks, with batteries. The export version of the radio receiver did not have a DV range, another KW subband was added instead. Overlapping frequencies can be viewed from the photo. Technical characteristics of the domestic version: Maximum sensitivity: on DV and CB 30 µV, on KV 20 µV. Real sensitivity: on DV 60, SV 40 µV, on KV about 30 µV. The adjacent channel selectivity is at least 36 dB. The attenuation of the signal of the mirror channel: on DV 36 dB, CB 30 dB, KV 14 dB. The intermediate frequency is 465 kHz. AGC action: when the input signal changes by 40 dB, the output signal changes by 6 dB. Band of reproducible sound frequencies: when receiving radio stations 100 ... 4000 Hz, when playing a recording through an external EDA - 100 ... 7000 Hz. Nominal output power with a non-linear distortion factor of 6% - 150 mW. The power source is six elements of type 373 Mars, Saturn, or a network of 50 Hz 127 or 220 V. The supply voltage is 9 V. The current consumed by the receiver in the absence of a signal of 12 mA. The power consumed from the network is not more than 1.2 watts. The efficiency of the receiver is maintained when the battery voltage drops to 5 V. The duration of the receiver from one set of cells is 150 hours. Bass amplifier sensitivity from the pickup jacks at a rated power of 200 mV. Dimensions of the receiver 488x240x280 mm. Mass RP 8 kg. Since 1965, the plant produced a modernized receiver "Motherland-60M2" practically no different from the first model.
