R-130M is HF, talk-back, simplex, telephone- telegraph radio set with single-side band modulation (SSBM) and crystal frequency control. R-130M is intended HF radio communication. R-130M has discrete frequency spectrum, ensures selection of a preset frequency and communication on fixed frequencies with radio sets of the same type, with HF radio sets from old stock that have AM (amplitude modulation) and on-off keying.
R-130M has 950 preset frequencies with 10 kHz gap.
- reception and transmission by telephone at SSBM;
- reception and transmission at AM;
- reception and transmission of telegraph signals at on-off keying (narrow band AT, or wide band AT);
- transmission of telegraph signals at FSK (frequency shift keying) FT-500 (FT)
- stand by reception at all indicated operation types except FSK (STAND BY).
At all types of communication the radio set operates in simplex mode. Distance control- switch from reception mode to transmission mode and communication are realized with the help of telephone TA-57-U through a two-wire line at distance up to 2 km.
The primary power source of R-130M is vehicular mains DC 26 V±15 %.
The radio set operates in temperature range from -40° С to +50° С and relative air humidity 95-98% (when t=40°С).
