LenGRC-400  LenGRC- 400 LenGRC 400

This vehicular radio system, GRC-400, is a transceiver with the maximum output power of 400 watts to cover the radio communications in the HF band. It has the capability of being installed on mobile system. This radio, which is working in frequency range of 1.6MHz to 30Mhz in simplex and half duplex modes, utilizes the analog modulations of AME, SSB, and SSBCW. This radio has RS-232, RS-485 and USB ports and there is possibility to remote the radio up to 4.5Km far. Showing the output power, VSWR and level of received signal on display are the other features of this system.
