Radiols and receivers p / p stationary.DomesticThe tabletop transistor radio "Solnechny-2" in 1961 was developed by the Leningrad NIIRPA them. Popov. The peculiarity of the receiver is powered by a small-sized remote solar battery together with a battery.

If it was necessary to listen for a long time, it was necessary to direct the light of the sun or a lamp of 60 ... 100 W to the solar battery. The receiver is assembled on 9 transistors according to a simple superheterodyne circuit. Ranges DV and SV. When working with a ferrite antenna, the receiver sensitivity is 5 mV / m. Selectivity on the adjacent channel 12 ... 14 dB. Rated output power 50 mW. Sound pressure frequency range 250 ... 4000 Hz. The receiver has an input for connecting an external pickup. On the left is the power and volume knob, then the button for the adapter input, the range of DV, CB and on the right is the tuning knob, with the numbers printed on it, which are the conventional scale of the receiver.
