Samyung SRG-1150DN

MF/HF RADIO EQUIPMENT

SRG-1150DN/1250DN(DSC, NBDP) MF/HF Radio Equipment, which is designed and developed for medium and long range communications, fully complied with all the requirements of GMDSS that can be installed on both IMO and non-IMO vessel. SRG-1150DN/12500DN(DSC, NBDP), which is intergrated with DSC unit, Direct Digital Synthesizer (DDS) and Noise blanker Circuit, enables reliable communications and also ease of installation owing to compact and light weight with NBDP function.
