JRS-914 10kW MF/HF Transmitter

The JRS-900 series radio transmitter is a general-purpose high performance fully solid-state HF transmitter.

The JRS-913/ 953/ 914 radio transmitter can provide an output power of 1kW/ 5kW/ 10kW peak envelope power (PEP) ,respectively.

Operating modes include telegraphy (CW), compatible AM (full carrier SSB), single sideband (reduced or suppressed carrier SSB), and frequency shift keying (FSK).

The transmitter is designed in compliance with relevant the ITU-R recommendations, the ITU radio regulations and the ICAO standards, and ensuring high reliability and easy of operation/maintenance.
The fully solid-state transmitter minimizes maintenance with safety and assures long life and low running cost, as compared with the conventional usual transmitters.

JRS-913/ 953/ 914 radio transmitter is a HF transmitter that is used for radio communication between:

coast station and ship stations
ground station and airplane stations

JRS-913/ 953/ 914 radio transmitter is usually remotely controlled from the control center.

The HF transmitter enables pre-setting for up to 100 channels within the frequency range from 2.0MHz to 29.9999MHz.

This transmitter is designed based on the international standards such as ITU-R and ICAO.
Available emission modes are telecommunication (CW) and telephone (full carrier SSB, reduced carrier SSB, and suppressed carrier SSB) and operation of FSK is also available by externally applying the FSK signal source (audio frequency signal) to the transmitter.
This transmitter is equipped with power supply units at the bottom, a PA unit and a matching circuit at the middle, and an exciter at the top of the cabinet.
