    R-250, R-250M and R-250M2 where the most prominent and remarkable Russian short wave receivers. The receiver line produced and modernised from 1948 until 1981. The designer was Anton Antonovich Saveliev, Yuri Alexandrov (U1SX) and others. The project was started in 1940 and finalished in 1946 - 1949. First named AS-1 and AS-2 (designers initials) The set took the Stalin Premium prize in the early 50's. While working on the design numerous other developments were taken into account, but no examples were actually obtained, so it is basically an original Russian design. AS-2 is an early version of R-250 and identical to it. Only the labels are different. Very few AS sets were produced, so it is a rare thing among the R-250 series radios. The design is very rugged. The set comes in a cabinet with two compartments and is made from Aluminium (Silumin) castings which are used on chassis etc.

    All R-250 series produced from 1949 till 1981 largely in Charkov Radio Works (later IU "Proton") and some in other factories. Name "Kit" - translated "Whale". The receiver was mainly used in soviet and her allied armed forces. Later often found in HAM radio clubstations.
