Small-sized radio tape recorder `` Gnome ''.
Cassette radio tape recorders, portable.DomesticA small-sized radio tape recorder "Gnome", an experimental development of the A.S. Popov State Research Institute of Radio Engineering and Mechanics in 1981. It is designed for reception in the MW and VHF bands, as well as for recording phonograms from the built-in receiver and microphone and subsequent playback of phonograms through a loudspeaker or telephones. The radio tape recorder provides for a temporary stop of the tape, offsetting from the interference generator of the magicalization when recording transmissions of CB radio stations, offsetting from interference, visual-acoustic monitoring of the state of the power source and the recording process, automatic adjustment of the recording level and other operational conveniences. The radio tape recorder can work both horizontally and vertically. The device can be disconnected into 2 parts: a receiver and a tape recorder; while the latter remains operational and can be used as a separate device. The radio tape recorder is designed to work with a microcassette, similar to the microcassette of the Japanese company Olympus Optic. Ranges: SV 571.4 ... 186.9 m, VHF 4.56 ... 4.11 m. Sensitivity in the range SV 2.5 mV / m, VHF 0.01 mV / m. Adjacent channel selectivity in the CB range of 22 dB. Selectivity in the VHF range of 20 dB. The range of reproducible frequencies in terms of voltage in the path: AM 150 ... 3150 Hz, FM 150 ... 7100 Hz, magnetic recording 100 ... 6500 Hz. Harmonic coefficient in the AM path 5%, FM 3%, magnetic recording 5%. Maximum output power 300 mW. The speed of movement of the magnetic tape is 2.38 cm / s. Knock coefficient ± 0.5%. The signal-to-noise ratio of the recording / playback channel is 44 dB. The relative erasure level is -55 dB. Supply voltage 4.5 V. Dimensions of the receiver 152x65x38 mm, tape recorder 140x130x38 mm, radio 152x195x38 mm. Weight 0.92 kg.
