Retevis RT97S Portable GMRS Repeater. This version features an updated case and a DB-9 Female connector for adding an external controller. The Retevis RT97S is an exciting new UHF repeater certified by the FCC for use on GMRS! The Retevis RT97S has FCC ID 2ASNSRT97. Featuring 8 GMRS repeater channels, a 10W transmitter with a full 5W 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 to 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 two handheld radios inside. Please note that this connector does not currently feature a discriminator output which is required for an external controller that will do the CTCSS/DCS tone decoding. However, the repeater can be configured to decode the tones internally. We have only tested it with a URIxB repeater interface for use with the myGMRS Network at this time.
