Stationary transistor radio "Melody-102".
Radiols and receivers p / p stationary.DomesticStationary transistor radio "Melodiya-102" from the beginning of 1976 was produced at the Riga Radio Plant named after Popov. The 1st class radio tape "Melody-102" is developed on the basis of the "Melody-101-stereo" model. It is designed for reception in the DV, SV, three sub-bands of HF and VHF, as well as for reproduction of gramophone records. The Melodiya-102 radio tape replaced the Rigonda-102 tube radio. The model uses EPU - II-EPU-60. The speaker has 4 dynamic heads: 4GD-35, 3GD-31 and two 1GD-40. The receiver has a BSHN system and a fixed tuning for 3 radio stations in the FM band. In 1977, a simplified version of the radio called Melody-102A was released, in the speaker of which only 3 loudspeakers were installed, one 4GD-35 and two 1GD-40. For the rest, with the exception of adjusting the denominations of the parts and their numbering according to the scheme, the radiola is the same. The absence of a high-frequency loudspeaker did not particularly affect the frequency response of the low-frequency path. Sensitivity when receiving on an external antenna: DV 150 μV, SV 100 μV, KB 100 μV, VHF 5 μV. When receiving on a magnetic antenna in the ranges DV 2 mV / m, CB 1.5 mV / m. Selectivity on the adjacent channel in the ranges DV, SV 40 dB. The steepness of the slopes in the FM range is 0.25 dB / kHz. The AGC system provides a 2-fold change in the output voltage, while the input signal changes by a factor of 1000. The reproducible frequency band of the AM path is 63 ... 6300 Hz, the FM path and EPU - 63 ... 12500 Hz. Rated output power 5 W, maximum 9 W. The power consumed from the network when receiving is 30 W, when the EPU is operating about 42 W. The dimensions of the radio without legs are 630x500x338 mm. Weight 23 kg.
