FAQ
1. What is the difference between 5W and 25W?
The difference in power can be significant. For example, using 5W of power, communication over a long distance might result in weak or no signal. However, with 25W of power, the range can greatly improve, allowing for clearer and more reliable communication over much longer distances.
While power is crucial, factors like antenna height also play an important role. In situations where elevation isn't favorable, higher power can be a big help in extending communication range.
2. Is the actual output power really 25W?
The factory output is between 22W-25W. However, when operating with a duplexer, there may be power loss, reducing output to around 15W-22W, depending on the quality, thickness, and length of the feeder cable.
3. What’s the GMRS Repeater Frequency Range (TX and RX)?
For users operating with GMRS, the frequency range of the RT97L is:
- TX (Transmit): 462.550 - 462.725 MHz
- RX (Receive): 467.550 - 467.725 MHz
This range allows for effective communication and operation in the designated GMRS frequencies, which are crucial for users who need clear, uninterrupted signals.
4. How Does Using a Raspberry Pi Enhance RT97L’s Functionality?
The RT97L portable gmrs repeater is designed with flexibility in mind. By connecting the repeater to a Raspberry Pi via its DB-9 interface, users can expand the repeater's functions. This allows for easy programming and the ability to customize the repeater to fit specific needs, whether you’re operating in a particular area, enhancing security, or fine-tuning performance.
5. What Is Amp Absorption in TX and RX?
- Receive Mode Absorption: 180mA
- Transmit Mode Absorption: 5.5A
6. How is the RT97L Waterproof Even if the Doors Are Uncovered?
The RT97L gmrs mobile repeater is rated IP66 waterproof, meaning it can withstand powerful jets of water from all directions. This rating ensures that it performs well even in harsh weather or environments with heavy water flow. However, to ensure optimal performance and longevity, it's always a good idea to install the repeater in a protected location, especially in areas with extreme weather conditions.
7. Does the RT97L Have an Internal Duplexer?
Yes, the RT97L portable repeater comes equipped with an internal duplexer, which is essential for enabling the repeater to work efficiently with an antenna. The duplexer allows the device to handle both transmit and receive signals simultaneously without interference.
8. How Many Channels Does the RT97L Have? And What Does It Mean?
The RT97L is capable of storing 16 different channels, which means it can quickly switch between up to 16 communication frequencies.
9. What is the RT97L's Duty Cycle?
The duty cycle for RT97L repeater is 100%.
10. What is the DB-9 Female Connector used for?
RT97S base station comes with a DB-9 port, which can be directly connected to the included speaker mic and is compatible with Raspberry Pi.
11. Does this repeater work with your handheld FRS units? Or just the GMRS radios?
Because of the limitations on FRS by the FCC, this repeater can be only ued for GMRS radio, no mater handheld GMRS radios or Mobile GMRS radios.
12. Is this repeater compatible with other manufacturers handheld GMRs radios that are repeater capable? For example BTECH, Radioddity, Midland?
Yes, the RT97L repeater is compatible with GMRS handheld radios that are repeater capable.

JulianRetevis RT97LReviewed on May 09,2025This repeater Retevis RT97L — and any type (UHF, VHF, GMRS, DMR) — would be great for my city, Bucharest, Romania. Unfortunately, there aren’t many active radio clubs here, and most old users focus only on HF because of the lack of repeaters, chasing DX and collecting trophies. That doesn't really reflect the true spirit of amateur radio, which should be about community and shared learning — not just individualism.DominicRT97L repeaterReviewed on May 08,2025I just received the RT97L repeater today and can't wait to try this. It's much smaller than I thought it would be, which is a good thing!JaxonWell madeReviewed on May 07,2025I initially had the first generation RT97 that worked flawlessly for years but went with the RT97S when it came out so I could link it nationwide. I have had great results with almost all of the Retevis products I have owned over the years. This being a new product, there was an issue with the programming software that Retevis has fixed. Retevis may be a bit difficult to deal with due to the time difference and language, but they have always solved any of the minor issues I have had with their new products.ChristianWorks great.Reviewed on May 06,2025I have in located at the top of a hill, in a fence line at the highest point on my property. It is powered by a marine deep cycle battery that is charged by solar panels.AustinGreat powerReviewed on May 05,2025This repeater replaced an RT97S that has been in service for a few years. No issues with it, other than the output power after the duplexer was about 4 watts. The new RT97L transmits at 21 watts (verified) after the duplexer. It has added about 10 miles onto my range and works in low spots or valleys that it didn't before.ZacharyYes great machine!Reviewed on May 04,2025Wonderful repeater. Getting 22 watts to the antenna feed line. Got A+ Tech support!TylerSmall but powerful GMRS repeater, must do firmware updateReviewed on May 03,2025I first had the transmit delay issue which it wouldn't transmit after keying a radio a couple of times, sent an email to Retevis and the next morning I had the instructions on how to download the firmware update and software for the update. To be fair my repeater's output is 30.1 Watts with the power supply which is more than advertised and it's working great after the update.RobertSo far so goodReviewed on May 02,2025So far so good . Haven't updated firmware,but no issues. Huge improvement in range from the 10 watt version.HunterAfter sale customer service FANTASTICReviewed on May 01,2025After sale customer service was FANTASTIC. Two thumbs up to the Retevis after purchase service and support. I am impressed!!!!AdrianBest gmrs repeaterReviewed on Apr 30,2025I live in a valley about 20 miles wide surrounded by high cliffs. By placing my antenna high in the valley floor I can clearly make and receive messages 20 miles away. Current draw in standby is amazingly low which easy works with a small 20 aH liFpo4 battery and 100 watt solar collector.
