It features integrated digipeater, dual receive, wideband capability and multi-mode capability. The new TH-D75E is the logical evolution of Kenwood’s popular TH-D74E dual-band handheld. Not only is the housing design of the TH-D75E reminiscent of its predecessor, but also the UI design and user guidance largely follow the proven concept. The device complies with IP54/55 standards and is thus protected against the ingress of dust and rainwater.
