Before diving into documentation, it helps to understand exactly what this device is. The Samyung SMR-3700 is a compact, high-performance marine navigation radar, not a VHF radio. Designed as a successor to the SMR-3600, it is a small-sized raster-scanning radar with a domed (radome) antenna delivering 4 kW of transmitting power, commonly used on vessels up to 300 gross tons. Its compact design and powerful performance make it a popular choice for small to medium-sized vessels in commercial and recreational maritime settings.
