DavidUse RT97 GMRS Repeater on CampingReviewed on Feb 21,2025As a radio operator with over 30 years of experience and a long-time Retevis customer, I have had the pleasure of using the RT97 GMRS Repeater for several years. I mostly use the repeater during camping trips with my family and Scouts, where portability and reliable communication are essential. I’ve shared my experience with the RT97 through a video and continue to rely on it for our outdoor activities. It’s become an indispensable piece of equipment for staying connected in places where traditional communication methods fail.Lindsey DalleyRT97 Repeater Saved Our Hunting TripReviewed on Feb 21,2025I use the Retevis RT97 GMRS repeater for personal use when my family goes hunting or camping in remote areas. In these rugged terrains, staying connected is crucial, and often the only option is to place the repeater on a high peak. This allows us to maintain communication down into the ravines and valleys below, where regular radio signals would fail. In September 2024, our family experienced firsthand just how essential this communication tool can be. Our pack horses got trapped in a dense wooded area under fallen trees, making it impossible to free them. In a situation like this, quick help was necessary, and thankfully, we had the RT97 repeater positioned high on a peak, allowing us to reach our base camp. With the repeater’s strong and reliable signal, we were able to get immediate assistance, and help was sent without delay. Though many around us assumed it was our radios that made the difference, the real hero was the Retevis RT97 repeater, which provided the necessary signal to stay connected in this challenging terrain.Tyron MilesGreat addition to our GMRS radio setup!Reviewed on Dec 11,2024It’s portable, easy to install, and greatly extends our radio range.Allen WeberWorking Great In the mountains of OregonReviewed on Oct 08,2024I get the RT97 repeater up and running It is doing a good job we’re talking about 19mile from cow camp to home Lots of hills and trees between us is siting around 5140’ and home is about 4100’NakliyeRetevis RT97 Portable GMRS Repeater Mobile RepeaterReviewed on Dec 23,2023I go to see everyday some websites and information sites to read articles or reviews, however this weblog presents quality based posts.NakliyeRetevis RT97 Portable GMRS Repeater Mobile RepeaterReviewed on Dec 19,2023If some one desires expert view concerning running a blog after that i recommend him/her to visit this webpage, Keep up the fastidious job.chen chen xiaoLONG-RANGE COMMUNICATIONReviewed in United States on Nov 15,2023Works perfectly FOR LONG-RANGE COMMUNICATION.
