The tuner "Radio engineering T-7111FS" has been produced for export since 1989 by the Riga software "Radio engineering". Created on the basis of the tuner "Radio Engineering T-7111S" and is designed for high-quality reception of mono and stereo broadcasting programs from the World Cup in the VHF band in two standards of stereo broadcasting (polar modulation and pilot tone) and broadcasting programs in the bands of CB and HF. The tuner provides: the ability to connect UZCH, tape recorder and stereo head phones, external antennas and magnetic antennas for the LW, MW and HF ranges, orientation of the magnetic antenna without changing the position of the tuner, adjusting the sound volume of stereo telephones, a fixed setting in all bands manually deactivated, as well as automatically deactivating when the knob is turned in the VHF range. The tuner has: indication of fine tuning, stereo mode, automatic switching of stereo modes - mono, wide band mode, Silent tuning in the VHF band, automatic adjustment of the sensitivity in the DV, SV and KV ranges, indication of the antenna input overload when receiving signals in the DV, SV bands and KV. Main technical characteristics: The range of received frequencies CB - 0.525-1.607 MHz. KV-1 - 7.1-7.35 MHz. HF-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. VHF-1 - 65.8-74 "‹"‹MHz. VHF-2 87.5-108 MHz. Sensitivity from an external antenna in the VHF range - 3 µV, SW, KV - 100 μV, from a magnetic antenna - in the SV range - 1.5 mV / m, KV - 1 mV / m. The adjacent channel selectivity with 9 kHz detuning in the CB, HF bands is at least 40 dB. The output voltage for connecting stereo phones with a nominal load resistance of 16 ohms is 150 mV. Power consumption 8 watts. Overall dimensions 430x360x72 mm. Weight without packaging 5 kg.
