Portable radio receiver `` VEF-222 ''.
Portable radio receivers and radios on p / p.DomesticThe portable radio receiver "VEF-222" has been produced by the Riga PO "VEF" since 1988. The receiver had several design options. The improved model "VEF-2221" differs only in the presence of an indication of the position of the range switch, in the window on the scale. Receivers were produced mainly for export. The receivers are provided with AFC of the local oscillator, AGC, silent tuning. The devices have jacks for connecting a headphone with a resistance of 50 ... 120 Ohm and a unified jack for a tape recorder. For reception in the LW, MW bands, the receiver has an internal magnetic antenna, and in the SW bands it is telescopic. Reception on all bands can also be carried out on an outdoor antenna. Sensitivity in the ranges: LW - 1.5 mV / m, MW - 0.7 mV / m, SW - 0.3 mV / m, FM - 0.05 mV / m. Adjacent channel selectivity 26 dB. The band of reproducible sound frequencies when working on FM 150 ... 10000 Hz. Rated output power 250 mW. The power supply is universal, from the mains and from 6 elements 373. The current consumption in the absence of a signal is not more than 14 mA, and at 150 mW, the output power is 35 ... 50 mA. One set of batteries, at an average volume, is enough for 100 hours of operation. Dimensions of the models are 297x247x80 mm, weight without batteries 2.3 kg. The VEF-222 radio receiver in design and parameters coincides with the VEF-221 model, except for the VHF range, here it is 65.8 ... 74.0 MHz or 88 ... 108 MHz.
