The three-program receiver "Vestnik PT-310" has been producing the Mayak Kursk plant since 1988.
The three-program wire broadcast receiver `` Vestnik PT-310 '' is designed to receive programs transmitted over a network of compacted wire hanging.
The PT provides reception of an audio frequency channel - (1 program) with or without amplification, radio frequency (RF) channels with carrier frequencies of 78 kHz (2 program) or 120 kHz (3 program).
The receiver has a signal output for recording to a tape recorder.
The design of the PT provides the ability to install it on a horizontal surface and mount it to the wall vertically.
Technical characteristics: range of reproduced sound frequencies by sound pressure on RF channels 200 ... 6500 Hz;
on low-frequency channels 200 ... 10000 Hz;
harmonic coefficient by voltage for the LF channel (main mode) 2%;
range of input signal change on 3CH channels 19 ... 30 V;
rated output power of 0.9 watts.
Power supply from an alternating current main with a voltage of 220 V. Power consumption is 4 W.
Dimensions PT - 335x95x130 mm.
Weight - 1.6 kg.
