Retevis RT97S Portable GMRS Repeater

  • Sale
  • Regular price $499.99

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 a plug-and-play kit (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, 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.

One slight problem

The repeater arrived well packed and works well. However the DC power supply was crushed. I was able to piece it back together with super glue and it works. I don’t anticipate needing to use it, so I’m not to worried about it.

No support

No way to update software and usb drivers from the manufactures website. I cant program the device because I am using windows 11 and the usb drivers that are on this page are not supported. So I have tried to contact the manufacturer and they have not responded. I will give it a few more days then Im returning it. You have to have the programing software to get it going. without being able to program it its useless.


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 .
