The portable transistor radio receiver of the III group of complexity "Russia-303-1" is created on the basis of the serial model "Russia-303" and differs little from it.
,86e6f450b8cc469628ba70bf2947b049
The radio receiver is designed for reception in the LW and MW ranges to an internal magnetic antenna and in 2 KB sub-bands to a telescopic antenna.
,86e6f450b8cc469628ba70bf2947b049
Power supply 4 elements 316. Current consumption, in the absence of signal 10 mA.
,86e6f450b8cc469628ba70bf2947b049
The operability is maintained when the supply voltage drops to 3.5 V. The duration of operation at an average volume from a fresh set of batteries is 50 hours.
,86e6f450b8cc469628ba70bf2947b049
The receiver has a regulator for fine tuning in the HF sub-bands, jacks for an external antenna and a miniature telephone.

,86e6f450b8cc469628ba70bf2947b049
The dimensions of the radio receiver are 215x125x47 mm.
,86e6f450b8cc469628ba70bf2947b049
Its weight is 1 kg.
,86e6f450b8cc469628ba70bf2947b049
Since 1987, the radio has been produced under the name "Russia RP-303-1".
,86e6f450b8cc469628ba70bf2947b049
In general, the radio receiver "Russia RP-303-1", like "Russia-303-1", was produced most likely to expand the range of names of the plant than as new models.
