RT97P DMR Repeater System for Large Businesses

Q: What are the main features of the RT97P and RT29D radio bundle?

The bundle pairs the RT97P, a 10W UHF 400-470 MHz portable DMR repeater with a built-in duplexer, 8 channels, and the ETSI TS 102 361 DMR protocol, with six RT29D handhelds: 10W/5W/1W power, 128 channels, IP67 waterproofing, dual time slots, 10-bit and 32-bit digital encryption, an optional Bluetooth version, and a 3200mAh battery. The repeater runs on DC12-24V, vehicle power, or solar, and ships with a 7.2dBi fiberglass antenna and a 15-meter feeder cable.

Q: How far can the RT97P DMR repeater actually reach?

The page quotes up to 10 miles of talking range, and that figure holds with the repeater antenna mounted high and in the open - the specific call distance always depends on the usage environment. No repeater has a single fixed range: antenna height, antenna gain, feed-line loss, terrain, and buildings all shape coverage. Mount the antenna high and in the clear, share your terrain with us, and we will help you plan a realistic coverage target.

Q: Do the RT29D radios work with the RT97P repeater out of the box?

They are designed to work together, but each RT29D must be programmed to match the RT97P repeater frequency pair, color code, and time slot using the programming software and cable. Tell us your target frequencies when ordering and our team can advise on programming before shipment.

Q: Does the RT97P system support encrypted communication?

Yes. The RT29D provides digital encryption in DMR mode - the specification lists 10-bit key and 32-bit encryption, preset through the programming software - and the RT97P relays standard DMR Tier II traffic in both time slots. If your compliance plan requires a specific cipher such as AES-256, confirm the exact configuration with our support team before rollout.

Q: Do I need a license to operate the RT97P and the RT29D?

It depends on your frequencies and region. The RT29D transmits on UHF 400-480 MHz and the RT97P on customizable UHF 400-470 MHz or VHF 136-174 MHz; business use in the United States generally requires an FCC business license such as Part 90. Share your country and planned frequencies with our team and we will confirm the licensing path before you order.

Q: Can the RT97P repeater be customized to UHF or VHF?

Yes. TX and RX frequencies can be customized within UHF 400-470 MHz or VHF 136-174 MHz, with the offset held between 5 and 12 MHz. Note your RX frequency, TX frequency, and offset when ordering, and the factory confirms feasibility before production. The duplexer can also be factory-tuned to specific frequency splits on request.

Q: Can RT29D radios talk to analog radios?

Yes. The RT29D operates in analog and DMR digital mode, so it talks directly with analog fleets and bridges teams that are mid-migration from analog to digital. Digital mode adds private call, group call, and all call on top of standard analog operation.

Q: How does the RT29D differ from the RT29?

The RT29D is the digital (DMR) version of the RT29 analog radio. Both share the rugged design, up to 10W power, and a 3200mAh battery, but the RT29D adds 128 channels against 16, dual time slots (DMR Tier II), digital encryption, an optional Bluetooth version, and digital audio that stays clear to the edge of coverage. The RT29 remains the straightforward analog choice.

Q: How long does the RT29D battery last on a charge?

The 3200mAh battery supports about 14 hours of workplace operation between charges, with long standby time for multi-day duty. Charging is covered too: each radio includes a desktop charger, and kit tiers add a six-way charger that recharges six radios or batteries at once.

Q: Is the RT29D waterproof for outdoor work?

Yes. The RT29D carries an IP67 rating: completely dustproof, and it works normally after 30 minutes in one meter of water. For car washes, wastewater plants, marinas, storm-season security details, and hiking or off-road clubs, that rating keeps radios running through weather that ends unprotected electronics.

Retevis RT97P DMR Repeater System with RT29D Handheld Radio Bundle

The RT97P DMR repeater system extends the communication range of the RT29D handheld radios for large business use, supplying up to 10 miles of talking range (the specific call distance depends on the usage environment). With a 10W digital repeater and IP67 waterproof DMR handhelds, this long range two way radio system keeps farms, construction sites, warehouses, rescue teams, mines, ports, and event crews connected where distance and buildings interrupt direct radio-to-radio calls.

Main Features of RT97P DMR Digital Repeater:

1. Complete Compact Repeater Bundle

The RT97P portable repeater bundle includes a 7.2dBi high gain fiberglass antenna (Retevis MA02) and a 15-meter pure copper low-loss feeder cable, so the repeater and antenna connect directly with no additional accessories - a complete compact UHF repeater kit for rooftop, tower, or vehicle mounting.

2. Customizable Frequency

TX frequency and RX frequency can be customized between UHF or VHF. If you need to customize the repeater, please note the following information when placing the order: RX frequency, TX frequency, Offset (Offset ≥5MHz and ≤12MHz).

3. Easy-to-Read LCD Display

The RT97P repeater has an LCD display that shows TX and RX frequencies, CTCSS/DCS codes, and bandwidth settings at a glance. Up and down keys change channels and CTCSS/DCS tones on site, and the same keys lock or unlock the keypad - no computer needed for field adjustments.

4. Multiple Charging Options

The RT97P runs on DC12-24V power, vehicle power, or a solar battery. Keep it at a fixed site, or power it from a vehicle outlet on a self-driving tour: in mobile base station mode it coordinates every vehicle in the convoy on one channel, which is how road-trip groups and event crews keep all cars reachable.

Main Features of RT29D Digital Handheld Radio:

1. Digital & Analog Mode

The RT29D operates in digital and analog mode, so your team can talk across DMR and analog fleets without replacing existing radios. Digital mode supports private call, group call, and all call - the three call types business teams use most.

2. IP67 Waterproof

The IP67 waterproof rating allows use in wet environments: the radio works normally after 30 minutes in one meter of water. For car washes, wastewater plants, marinas, and storm-season job sites, that rating decides whether a radio survives the shift.

3. Long Battery Life

A 3200mAh large-capacity battery supports about 14 hours of workplace operation between charges, with long standby time that covers a full shift without frequent charging.

4. Digital Encryption

In digital mode, encryption keeps communication private. It is preset through the programming software, and the RT29D supports 10-bit key and 32-bit digital encryption - configured before the radios reach the field.

5. Dual-Time Slot

Dual time slot technology carries two group calls at the same time without interference, improving frequency efficiency in busy communication areas. Connected through the RT97P repeater, each call also covers twice the distance of direct radio-to-radio contact.

6. Convenient Charging

Each RT29 two way radio includes a desktop charger, and this kit adds a six-way charger: charge a single radio or battery at a time, or six at once, so every radio starts the shift fully charged.
