Radio `` Speedola ''.

Portable radio receivers and radios on p / p.DomesticThe portable transistor radio "Spidola" has been produced by the Riga State Electrotechnical Plant VEF since the 1st quarter of 1960. Radio `` Spidola '' (PMP-60) stands for Semiconductor Small-Size Receiver, 1960. "Spidola" is one of the first mass-produced portable semiconductor radio receivers in the USSR. This is a class 3 superheterodyne assembled on 10 transistors, designed to receive radio stations in stationary or field conditions in the ranges of long 150 ... 410 KHz, medium 520 ... 1600 KHz and in the short wave sub-bands: KV-5 ... KV -1 75 ... 52, 49, 41, 31, 25 meters. Reception is made to a magnetic antenna in the LW, SV bands and to a telescopic retractable antenna in the HF sub-bands. It is possible to connect an external antenna. The sensitivity of a radio receiver with a magnetic antenna on DV is 2 mV / m, CB is 1.5 mV / m. In the HF sub-bands with a telescopic antenna 50 ... 100 μV. Selectivity on adjacent channels, with detuning by plus / minus 10 kHz - 36 ... 40 dB. IF wound 465 KHz. IF bandwidth at 6 dB attenuation is 8 kHz. The rated output power on the 1GD-1 VEF loudspeaker is 150 mW, the maximum is 300 mW. The range of reproducible sound frequencies is 300 ... 3500 Hz. An external speaker system was developed for the receiver, in which a 3GD-9 VEF loudspeaker with an increased sound pressure and a reproducible frequency range of 100 ... 4000 Hz was used. The radio has sockets for connecting a piezoelectric pickup to it. Power is supplied from six A-373 cells or from two KBS-L-0.5 batteries. Dimensions of the radio receiver 275x197x90 mm. Weight without batteries 2.2 kg. Retail price of 73 rubles 40 kopecks from April 1961. The Spidola radio receiver meets all the basic requirements for class 2 battery receivers in accordance with GOST 5651 of 1951, but was placed in the third class since there was no GOST for portable transistor receivers. The corresponding GOST 5651-64 appeared in 1965, after which the line of receivers of the VEF plant was transferred to the 2nd class.
