Popov, together with the Novgorod PO Start, based on the Svirel serial radio receiver. Like the prototype, the Lel is intended for reception in the MW range with a built-in magnetic antenna. The solar battery was developed at NPO Kvant from monocrystalline silicon with a working area of 70 cm. The dimensions of the SB are 115x65 mm, the power output at an illumination of 500 W / m is 300 mW. In conditions of illumination of 250 W / m, (light cloudiness), it ensures the operation of the radio receiver without consuming the energy of the elements. SB is located on the hinged cover from the rear wall and is protected by glass. SB hinges allow you to rotate it around its axis by 180 degrees. Receiver sensitivity 2 mV / m, selectivity 12 dB, mirror channel 26 dB. Rated output power 40 mW, maximum 100. Operating frequency range 450 ... 2500 Hz. Minimum supply 2 V, nominal 3 V, maximum 6 V. Quiescent current 15 mA. Receiver dimensions 145x72x25 mm. Weight 240 g. Price 54 rubles.
