The radio station Angara-1 has been producing the Egorshinsky radio plant since the beginning of 1982. "Angara-1" - a series of KV wide-range radio stations for non-tunable radio communication in the range of 1.6 ... 8 MHz. Types of work: USB and single-band telegraphy. Output power up to 10 watts. Classification by purpose: Angara-1 (2R20N-1) - wearable, with a battery designed to work during stops; Angara-1C (2Ð 20С-1) stationary, not designed to work in motion; Angara-1U (2P20U-1) universal. Classification by the number of channels: Angara-1H-1 (2Ð 20Ð-1), Angara-1C-1 (2Ð 20С-1), Angara-1U-1 (2Ð 20У-1) multichannel; Angara-1H-2 (2P20N-2), Angara-1S-2 (2P20S-2), Angara-1U-2 (2P20U-2) up to 10 channels. Radio stations were produced with precise tuning to the frequency and tuning only to the channel. Specifications: Frequency range: 1.6 ... 7,999 MHz. Step tuning synthesizer: 100 Hz.
