Transistor radios "Lastochka-2" and "Lastochka-2M" from 1962 and 1963 respectively produced Dnepropetrovsk radio plant. Since 1962, together with the release of the receiver "Swallow", the plant began to produce an upgraded receiver "Swallow-2". It works in the range of DV and ST. The sensitivity of the radio receiver in the range of DV - 2.5 mV / m, SV - 0.8 mV / m. The selectivity in the range of DV - 16 dB, CB - 20 dB. The frequency range of 450 ... 3000 Hz. Rated output power 100 mW. Dimensions of the receiver 146x88x400 mm. Weight 450 gr. Includes leather case. Since 1963, the plant produced a batch of '' Lastochka-2M '' radio receivers, which from 1964 began to be called "Saturn". In terms of appearance, electrical circuit and design, the Lastochka-2M receiver is similar to the Saturn receiver, except for the input antenna circuit, which was the same as used in the Topaz-2 model. The added letter "M" was noted only in the passport of the receiver.
