Retevis Original Design The built-in sound card can be connected to the Raspberry Pi through a data cable. (data cable sold separately) This version features an updated case and a DB-9 Female connector for adding an external controller for linking purposes. You can add this repeater to the myGMRS Network by purchasing a linking bundle or an all-in-one kit that is plug-and-play (coming soon). Featuring 8 GMRS repeater channels, full 5W of output power after the duplexer, and a built-in notch duplexer, all you need to do is add an antenna and feedline to get on the air. Built into a cable TV amplifier box, the RT97S is rugged and water-resistant. Two power adapters come with the repeater, a 12V/24V cigarette lighter plug, and an AC adapter. A USB programming cable is also included so you can program the repeater to your channel and CTCSS/DCS tones of choice. The RT97S is ideal for solar-powered repeater sites where low power and a small footprint are required. At such a small portable size, this repeater is perfect for camping trips or emergency preparedness. Inside the case, there is a small 10W notch duplexer, an LCD display, a DC-DC power adapter, and the integrated radio module itself. This repeater does NOT simply have 2 handheld radios inside.
