The stationary transistor radio "Ermak" from the beginning of 1979 produced the Omsk Kozitsky instrument-making plant. Table souvenir "Ermak" with the emblems of the city of Omsk is a direct amplification radio receiver, which operates in the ranges of long (LW) and medium (SV) waves. The souvenir can also be used as a short-term low-power lamp. The radio is assembled on nine germanium transistors. Souvenir "Yermak" has a switch of the type of work and a knob for tuning to broadcasting stations. The volume control in the souvenir is not provided. The ranges of received radio frequencies: long waves of 145 ... 700 kHz, medium waves of 500 ... 1700 kHz. The selectivity of the neighboring channels in the range of the Far East - 8..10 dB, SV - 6 ... 8 dB. The sensitivity of the magnetic antenna in the ranges of the Far-East, SV - 5..7 mV / m. Rated output power - 100 mW, maximum - 150 mW. The range of reproduced sound frequencies is 250 ... 5000 Hz, a sufficiently high-quality sound, which is somewhat spoiled by the location of the loudspeaker on the back wall of the souvenir, with the output of sound pressure to the same. Power is supplied from a KBS-L type battery with a voltage of 4.5 V. In 1988, the electric circuit of the souvenir was transferred to silicon transistors in the same quantity. Receiver specifications are the same.
