FAQ
The RT97P is a 10W full-duplex DMR portable repeater in a mini cable-TV-amplifier-style body. It runs on DC 12-24V, car power, or solar battery, works in both DMR digital and FM analog modes, and covers customizable UHF 400-470 MHz or VHF 136-174 MHz frequencies. This listing pairs it with RT81 DMR handhelds and an FRP antenna.
The RT97P is the 10W DMR/digital model in this kit. The RT97 and RT97S are analog full-duplex GMRS repeaters (10W class), the RT97L is the 25W analog GMRS model, and the RT97LD is the 25W DMR model. Choose by protocol (DMR vs analog GMRS), power (10W vs 25W), and your local band rules.
The RT81 is a 10W UHF DMR handheld with dual time slots and an IP67 waterproof body. It shares the repeater's customizable UHF frequencies, so the radios and repeater work as one DMR network out of the box once programmed to your pairs.
Note four details when placing your order: RX frequency, TX frequency, offset, and charger type. Frequencies are customizable within UHF 400-470 MHz or VHF 136-174 MHz, and the offset must stay at or above 5 MHz and at most 12 MHz.
Yes. The repeater's duplexer is tuned at the factory to your RX/TX pair as long as the offset stays inside the 5-12 MHz window. An inquiry example of TX 151.070 / RX 155.295 MHz (4.225 MHz split) fits this window and can be handled as a customization request.
The repeater follows the ETSI-TS102 361 DMR protocol family, and encryption support depends on the DMR tier and configuration of the specific unit. Basic DMR privacy features are part of the standard; confirm current AES 256 availability for your order with Retevis support before purchase.
Yes. The repeater accepts DC 12-24V power, car power, and solar battery input, and Retevis positions it for solar-powered repeater sites where low draw and small footprint matter. Pair it with a 12V or 24V solar battery setup for off-grid farms, cabins, and emergency sites.
Coverage depends on terrain, antenna height, and interference; Retevis positions the kit as a long-distance solution for farms, events, and remote sites. With the FRP antenna mounted high and clear line of sight, teams report multi-mile ranges; concrete and hills reduce it. Customizable frequencies let you match the pair licensed for your area.
Both the repeater and the radios are programmable, so they are set to the same RX/TX pairs, DMR color code, and time slots. You can request factory programming to your licensed pairs when ordering (note RX, TX, offset, and charger type), or program in the field with the DB9 to USB cable.
Yes. Dual mode covers DMR digital and FM analog, and the standard mode list includes DMR, FM, and DMR+FM. Analog fleets keep working through the repeater while you phase in DMR handhelds like the RT81.
The transmitter spec lists the ETSI-TS102 361-1, -2, -3 DMR protocol family, the Tier-conformant standard for DMR Tier I/II equipment. That is the same protocol family used by mainstream DMR handhelds, which is what lets the repeater bridge brands that conform to it.
DMR radios that conform to ETSI-TS102 361 and are programmed to the same frequency pair, color code, and time slot can use the repeater. Retevis DMR handhelds such as the RT81, RT29D, and HD2 are the direct fits; third-party DMR Tier II radios work when programmed to match.
Both are 10W UHF DMR handhelds. The RT81 is this kit's dual time slot radio with an IP67 body; the RT29D adds Bluetooth and a longer-range heavy-duty build. Choose the RT81 for kit simplicity and repeater pairing, or the RT29D when Bluetooth headsets and extended field use drive the decision.
The product photos show the DB9 to USB cable among the kit accessories (a customer also asked exactly this before ordering). Treat the photo set as the packing reference and confirm the cable inclusion for your specific variant with support at order time, since bundles vary by SKU.
Three inputs: DC 12-24V, car power via the 12V/24V cigarette-lighter plug, and solar battery. The AC wall adapter covers fixed sites, the car charger covers vehicles, and solar covers off-grid repeater sites.
The repeater body measures 280×210×75 mm and weighs 2,624 g; the shipping package is 310×283×170 mm at under 3 kg. It is a single-hand-carry portable that deploys on a desk, shelf, or vehicle seat.
FRP stands for fiberglass, the material of the high-gain outdoor antenna that feeds the repeater. Fiberglass antennas handle weather and wind exposure well, which is why they are the standard choice for fixed repeater sites. Exact gain figures for this kit follow the shipped configuration.
Five variants run from 2 to 50 RT81 radios: 2 Packs for trials and small farms, 6 Packs (with optional 6-way charger and mics) for shift teams, and 20 or 50 Packs for site-wide or multi-team rollouts. Most teams start small, validate coverage, then scale to the 20/50 packs.
The repeater is customizable within UHF 400-470 MHz and VHF 136-174 MHz, and Retevis takes customization requests for regional frequency plans. Approval itself depends on your local regulator: order the unit programmed to a band your license covers, then register per local rules. Support can confirm what is programmable for Sweden, the UK, and other regions before you order.
Custom frequency orders take about 4 weeks to customize after your frequency details are confirmed. Standard orders dispatch within 24 hours, and international delivery runs 7-10 business days, with cash on delivery available in supported regions.
The page targets farming, camping, and emergency preparedness; real inquiries extend the list to conventions and trade shows (22 radios on itinerant frequencies), motorsport events needing 3-5 miles, school districts, and eco-tour operations. The common thread is a fixed low-power site plus handheld fleets that need multi-mile DMR coverage.
Both are DMR repeaters. The RT97P is this kit's 10W mini portable with solar-ready 12-24V input; the RT97LD is the 25W customizable portable for larger coverage. Choose the RT97P when low draw, small footprint, and kit simplicity lead; choose the RT97LD when 25W output is the requirement.
