New model! 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).

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, 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.

* 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.

Customer Reviews

Based on 4 reviews

the portable use of this repeater system is perfect for camping, prepper use, or use around the your property,
its list as 5 watts but the unit it self puts out 10 watts, i can get almost 10 miles on solar and dc power!

18 Months of Operation, Flawless

An update after 18 months of operation: The Retevis RT97S unit has performed flawlessly. Its low current draw on standby, is an advantage for a solar-powered repeater. Simple and robust; good build quality. The quality is similar to that of commercial equipment (and far better than consumer-grade electronics).

The ability to use the built-in control pad to change its "channel" was useful. Initially when we set up the repeater, we had programmed several channel/CTCSS/DCS combinations into it. We "went live" using our older configuration and everything worked. We later updated all our radios in the field to use new CTCSS/DCS settings, then switched the repeater to use them too.

We were able to go to the repeater site, press arrow-up on the control pad, and select the new configuration. We did not need a computer at the repeater site - we merely selected the other channel+DCS config that we had programmed-in months before. Simple!

This is an update to the review I posted on Dec 06, 2021.


Took some doing i am new at this .but a friend of mine as a older one ,he loves it too .i gor mine set up and wow the bew 97s is very awesome .i cant beleave how far i get out with it . In fact i just ordered a 40 foot mast for it .the foot print is gping to be very large .i think they really did it this time .yes i would buy it again still may checking to ser if they can be linked .love it

Works well

The Retevis unit is well-made. It serves our purpose as a GMRS repeater in a solar-powered system, for resident emergency-response work (CERT / Community Emergency Response Team). Simple and robust; good build quality.
