Portable radio receivers "Spidola-207" and "Spidola-208" since 1972 produced the State Electrotechnical Plant VEF. Portable transistor radio receiver of the 2nd class "Speedola-207" is designed to receive programs of broadcasting stations in the bands DV, SV and KV, as well as radio stations operating in the VHF band with FM. The main difference between the Speedola-207 and the previous model of the VEF-201 is the presence of a VHF range. There are other innovations aimed at improving the sound quality of the receiver and improving operational properties. In the amplifier LF introduced tone control on the LF, reducing current consumption and improving the quality of speech programs. The level of nonlinear distortions is reduced due to the negative feedback circuits covering the individual stages of the LF amplifier. The scheme for applying the AGC voltage to the first stage of the IF amplifier has been modified. In the VHF unit introduced automatic frequency control. The control over the tuning to the station is carried out by an arrow indicator. The receiver speaker consists of a 1GD-4A loudspeaker mounted on the front panel of the case. It feeds the receiver '' Spidola-207 '' from 6 elements of type 373. The dimensions of the receiver are 310x200x95 mm, weight 3.8 kg. Together with the model "207", the plant produced the radio "Spidola-208", which was distinguished only by the absence of an indicator and inscriptions on the body, for expanding the range.
