<\/a><\/figure>\n<\/div>\n\n\nHF radio receiver R-311 “Omega”- Soviet shortwave radio for military use with self-powered.<\/strong><\/h2>\n\n\n\nThe receiver was developed in the design bureau of the Aleksandrovsky radio plant since 1949 on the basis of the R-253 “Alpha” receiver. Serial production began in 1954, entered service in 1956. Production continued until at least 1975. Produced at least 60,000 pieces.<\/p>\n\n\n

<\/a><\/figure>\n<\/div>\n\n\nOne of the most common tube connected receivers in the Armed Forces of the USSR. Intended for range 1 to 15 MHz in five scales. Receives AM, CW. The receiver is assembled according to a superheterodyne circuit with one frequency conversion on eight 2Zh27L pentodes.<\/p>\n\n\n

<\/a><\/figure>\n<\/div>\n\n\nThe frequency range of the receiver is divided into five sub-bands:
(I) 1.0 – 1.88 MHz
(II) 1.88 – 3.30 MHz
(III) 3.30 – 5.58 MHz
(IV) 5.58 – 9.20 MHz
(V) 9.20 – 15.0 MHz<\/p>\n\n\n\n
The receiver is a superheterodyne design with one frequency conversion.<\/p>\n\n\n
