The stationary transistor radio "Integral" from I quarter of 1980 produced Dnepropetrovsk radio plant. All-wave military receiver "Integral" with universal power is designed to receive broadcasts with amplitude modulation in the ranges of DV, SV and KB and c frequency modulation in the UHF band. The receiver is designed to complete the military radio broadcasting nodes or use it as part of marching technical propaganda tools. Radio reception is carried out on a ferrite antenna in the ranges of DV, SV and telescopic in the ranges of KB and VHF. It is possible to receive on all bands to external antennas of the type "Oblique beam" or "Pin". When operating from an external antenna, the ferrite antenna turns off. The receiver has external antenna and ground connections; power supply; loads; VHF antenna; an amplifier or tape recorder to record; phones with simultaneous shutdown of loudspeakers. For reliable radio reception in the scheme there is: a device to protect the input from overloads; silent adjustment with adjustable threshold; switching the UPCH AM band at 6, 9 and 12 kHz; light indicator fine tuning on the station; double frequency conversion in the HF bands. For convenience, there are: three scales with backlight of the corresponding operating range; mechanical latch settings to eliminate detuning when exposed to vibration loads; there is a standby mode to reduce battery consumption during long and continuous operation of the receiver; battery discharge indicator.
