Superheterodyne with one 112 kHz IF frequency conversion. The receiver range provides the ability to receive radio signals at frequencies from 175 to 12000 kHz (1714 – 25 m).<\/p>\n\n\n

\n
\"The<\/a><\/figure>\n<\/div>\n\n\n

The entire range of the radio receiver is divided into 5 sub-ranges:
1 subband 175 – 350 kHz;
2 subband 375 – 875 kHz;
3 subband 900 – 2150 kHz;
4 subband 2150 – 5000 kHz;
5 subband 5000 – 12000 kHz.
On subbands 1 and 2, the frequencies are indicated in the table on the front panel of the radio; on 3, 4, and 5 subranges – are applied directly to the scale. There is no graduation on the sub-bands “I” 173-350 kHz and “II” 350-875 kHz, it is replaced by an exact scale broken into 180 degrees.<\/p>\n\n\n
