CalvinWonderful repeaterReviewed on May 16,2025Wonderful repeater. Getting 22 watts to the antenna feed line. Got A+ Tech support!MichaelGreat RepeaterReviewed on May 14,2025they work great. I have the S and L. They are easy and work out to 20 miles with my setupDougieRT97L Repeater Kit with Antenna Use for RanchReviewed on May 12,2025I set up RT97L Repeater for my ranch in Bushness, FI. It works well. The tower is now 30' And the antenna came with the system from Retevis. Tower is now 30' & MA09 High Gain 462~467MHz GMRS Omni-Directional Base Antenna 4.5/7.2 dBi High Gain Fiberglass Antenna 5.75’. I will recommend to my friends.David25w GMRS RepeaterReviewed on May 12,2025I have the RT97S 5watt version of this and it gets me around 10 miles through the piney woods area of Texas. I would like to see if I get more from the 25Watt version. I use a 9db gain Comet CAF-712EFC Antenna about 30ft up, and with my 50w base it can reach about 50-70miles, so I'm curious to see if it would work the same for a repeater.JacobRT97LReviewed on May 07,2025So far mine has been working great! Very happy with it. Been testing it with some of the other ranchers so far in heavy woods we have gotten 14 miles south and 12 miles north of me so far.JamesRT97L GMRS repeaterReviewed on Apr 27,2025I recently purchased an RT97L GMRS repeater. It has amazing clarity and receive sensitivity, great job,. I would like to make you aware of an issue the repeater has of falling asleep after an overnight with no use. If you very long key the repeater or short key it 4 times it wakes and is good for the day with activity.gcrt97lReviewed on Apr 26,2025nice unit. very solid construction. 21w on .625. easy to program.impressive.Jared MyersRT97L-A rapid deployment unitReviewed on Apr 21,2025My goals for this repeater were to be used as a rapid deployment unit. We have a few full sized station repeaters in my area but I wanted something I could deploy quickly and anywhere I needed to for recreational or emergency. The requirements were waterproof, Ac/Dc compatible, solar usable and durable. The RT97L has fit all these requirements. The antenna and coaxial cable sent has worked flawlessly. The output has been very clear and it will do everything I want it to. As you can see in my pictures I have this set up as a rapid deployment unit. Most users have it in a box and all set up for daily use. Being able to set up and deploy this repeater anywhere I need to is a huge asset. Top notch product and I could not be happier. On my testing I was able to speak with people over 90 miles away due to my location and antenna placement. The repeater received good reviews across my test users and we all are glad to have this unit for the moments where we will need it. The build quality is perfect. It is heavy duty and does not feel like it will break easily. I would absolutely purchase this repeater/antenna again and would highly recommend this to others who are looking for a similar system.DENNIS GOETHERT97L Day !Reviewed on Apr 18,2025Just unboxed it, connected it to a KB9VBR copper J-Pole 35' above ground with a 1.01:1 SWR on 75' of LMR 400 coax. The SWR/Power meter shows it transmitting at 20.3 watts. It will replace a fully operational linked RT97S that has been in service for a few years and has worked flawlessly. The RT97S replaced a first generation RT97 that also worked flawlessly for years. This is a solar powered remote setup so my main concern is how the additional transmit power will impact battery life during the winter months when the solar charging at its minimum. The RT97S transmitted at 4 watts. Retevis said this RT97L draws 6 amps DC with a 100% duty cycle while transmitting on high power. If that is true, I should not have a problem. This one is larger and heavier than the first two generations. All are well built and rugged. So far, the only issue is that I need to change the privacy tones, but the software has a password that was not provided. If anyone knows what that is, I would greatly appreciate you sharing it. I will do another review after I have this placed in the remote location. It is on a hilltop and with the 4 watts the RT97S transmits at, has a 30 mile range, unless you are in a valley.VerdaAs advertised good transceiverReviewed on Apr 17,2025For GMRS transmission and multi-frequency receiving, this radio does well, as advertised. You will find the radio to be quite versatile - for the $. I like it well enough that I am considering adding another to a second vehicle . For mobile operation, I use a GMRS -specific magnetic mount antenna - works great!
