Standard Horizon Explorer GX1800 Fixed-Mount VHF Radio with NMEA 0183 and GPS

Standard Horizon's GX1800 Series Marine VHF/FM Marine transceiver is designed to be used in International, USA, Canadian and other region marine channels and can be operated from 11 to 16V DC, with a RF output power of 1W or 25W. The GX1800 Series is capable of DSC (Digital Selective Calling) ITU-R M.493 Class D operation. Class D operation allows continuous reception of Digital Selective Calling functions on channel 70 even while receiving calls on the voice channels.
