shortwave radio station independent frequency selection controller

Independent selection of communication frequency: the radio station has built-in full-band scanning receiving system, spectrum analysis system and frequency detection system, which can independently select communication frequency through detection, and can receive detection or calling signals in full-band in real time. It does not need preset frequency meter, additional service channel guarantee, frequency planning, contact documents and short-wave professional ability of operators, so as to quickly select communicable frequency and establish link, the radio station users can use the radio station as if they were on the phone, which is simple, easy to use and easy to use, and greatly improves the communication rate and signal quality of the short-wave radio station.

    Independent selection of communication frequency: the radio station has built-in full-band scanning receiving system, spectrum analysis system and frequency detection system, which can independently select communication frequency through detection, and can receive detection or calling signals in full-band in real time. It does not need preset frequency meter, additional service channel guarantee, frequency planning, contact documents and short-wave professional ability of operators, so as to quickly select communicable frequency and establish link, the radio station users can use the radio station as if they were on the phone, which is simple, easy to use and easy to use, and greatly improves the communication rate and signal quality of the short-wave radio station.

    (1) Independent selection of communication frequency: the radio station has built-in full-band scanning receiving system, spectrum analysis system and frequency detection system, which can independently select communication frequency through detection, and can receive detection or calling signals in full band in real time. It does not need preset frequency meter, additional service channel guarantee, frequency planning, contact documents and short-wave professional ability of operators, so as to quickly select communicable frequency and establish link, the radio station users can use the radio station as if they were on the phone, which is simple, easy to use and easy to use, and greatly improves the communication rate and signal quality of the short-wave radio station.

    (2) Key chain communication service: after the two sides of the radio station establish a communication link, real-time voice, SMS,

    Communication, such as message, can meet most of the emergency communication needs.

    (3) Non-chain communication service: the system applies fast frequency agility technology to realize non-chain communication function for the first time, and its "random disorder" frequency mechanism increases the difficulty of signal interception; Its integrated design mechanism of "priority frequency" and "low-speed hard resistance" combines "short-wave frequency" and "disorderly frequency agility, under the complex electromagnetic environment and the enemy's" analytical suppression "interference conditions, it can carry out relatively reliable near, medium and long-distance anti-interference communication, and can carry out non-real-time voice communication (similar to mobile phone WeChat voice communication), short message communication, and battlefield situation monitoring (the command center radio station automatically asks for Beidou positioning information of the mobile station and marks the travel track of the mobile station on the terminal electronic map). It is especially suitable for the working environment where the available communication frequency changes frequently due to the rapid movement of vehicles, ships, aircraft, etc.

    (4) Automatic link maintenance: The system's newly designed automatic link maintenance function. After the communication link is established, the radio will automatically maintain the link within a set time interval when the service is idle. If the channel quality cannot meet the communication requirements, the system will automatically replace the available channel to keep the communication link in a stable and reliable state.

    (5) When the signal-to-noise ratio is low, the sound code can be transmitted (rate 600bps): the performance of the sound code can be improved by selecting the waveform suitable for short-wave channel transmission and optimizing the coding algorithm, so that the signal-to-noise ratio of the sound code can be as low as-5dB, which is 5 dB higher than the sound code performance of the existing short-wave radio station.

    (6) High-efficiency message transmission: Design new data transmission waveforms and improve coding efficiency, combined with data transmission rate adaptation technology (75bps to 600bps rate adaptation) to achieve high-efficiency and reliable message transmission.

    (7) Ultra-low-speed datagram transmission: The newly developed ultra-low-speed datagram transmission technology can receive low-speed datagrams during frequency analysis, and the receiving signal-to-noise ratio can be as low as-25dB, which is 7dB higher than the low-speed datagram transmission performance of existing short-wave radio stations.
