The Volna-K is a Russian Navy HF receiver. It was made in the Petropavlovsky Radio Factory, in Kirov, USSR. About 70,000 were made from 1959 to 1985. It was meant both for the Navy and the merchant marine. It is a superheterodyne double conversion HF receiver, using 17 miniature valves, and 2 semi-conductor diodes. The valves have Russian numbers, but are equivalent to common American types. It can run off 110 or 220 volts AC, or 28 volts DC. It is intended to receive AM and CW signals down to 0.5 uV levels. The word "volna" translates to "wave". The frequency coverage is 12 kHz to 23 mHz in 9 bands, with gaps around the IF frequencies. There are 3 versions of the Volna-K, each with a slightly different frequency coverage. There is also Volna-P which is the version for submarines. (© Ray Robinson, VK2ILV, at
