Tuner '' Radio engineering T-7111FS ''.
Radiols and receivers p / p stationary.DomesticThe tuner "Radiotekhnika T-7111FS" has been produced for export since 1989 by the Riga PO "Radiotekhnika". Created on the basis of the radiotekhnika T-7111S tuner and is intended for high-quality reception of mono and stereo FM broadcasting programs in the VHF range in two stereo broadcasting standards (polar modulation and pilot tone) and broadcasting programs in the MW and HF bands. The tuner provides: the ability to connect an ultrasonic frequency converter, a tape recorder and stereo headphones, external antennas and a magnetic antenna for the LW, MW and HF bands, orientation of the magnetic antenna without changing the position of the tuner, adjusting the sound volume of stereo phones, fixed tuning in any range, automatic frequency adjustment in all bands , manually turned off, and also turned off automatically when you rotate the tuning knob in the VHF range. The tuner has: indication of fine tuning, stereo mode, automatic switching of stereo - mono modes, wideband mode, Silent tuning in the VHF range, automatic sensitivity adjustment in the LW, MW and HF ranges, indication of the antenna input overload when receiving signals in the LW, MW ranges and KV. Main technical characteristics: The range of received frequencies of MW - 0.525-1.607 MHz. KV-1 - 7.1-7.35 MHz. KV-2 - 9.5-9.9 MHz. KV-3 - 11.55-12.1 MHz. KV-4 - 15.1-15.45 MHz. KV-5 - 17.7-17.9 MHz. UKV-1 - 65.8-74 MHz. VHF-2 87.5-108 MHz. Sensitivity from an external antenna in the VHF range - 3 μV, CB, HF - 100 μV, from a magnetic antenna - in the CB range - 1.5 mV / m, HF - 1 mV / m. Selectivity on the adjacent channel with a detuning of 9 kHz in the ranges of MW, KV is not less than 40 dB. The output voltage for connecting stereo telephones with a nominal load resistance of 16 Ohm is 150 mV. Power consumption 8 W. Overall dimensions 430x360x72 mm. Weight without packaging 5 kg.
