Learn about DMR Repeater and the Retevis RT97P Portable DMR Repeater

Besides analog repeaters, DMR (Digital Mobile Radio) repeaters are also an ideal solution for extending the range of your two way radios. They can communicate with both digital radios and analog radios. Whether you're working in remote locations or crowded areas, DMR repeaters are essential for maintaining effective communication. Here's a simple breakdown of how DMR repeaters work and their key benefits.

What is a DMR Repeater?

A DMR repeater is a device that receives DMR signals and re-transmits them, allowing for communication over greater distances than a handheld radio can achieve alone. This is especially helpful in places with obstructions, like mountains, buildings, or dense forests. DMR repeaters use Time Division Multiple Access (TDMA) to allow multiple communications on the same frequency without interference, making them efficient for both digital and analog signals.

 Benefits of DMR Repeaters

1. Extended Range

DMR repeaters can significantly extend the range of your radios, allowing communication over long distances, even in remote or rugged areas like construction sites, mines, or mountainous regions.

2. Better Signal Quality

Repeaters improve the signal quality, ensuring clear and reliable communication, even in noisy or crowded environments where static and interference might be a problem.

3. Wider Coverage

With a DMR repeater, you can cover a larger area, which is perfect for businesses or organizations that need to stay connected across large work sites, ports, or public safety operations.

Retevis RT97P UHF Portable DMR Repeater with Antenna Bundle

Retevis RT97P DMR repeater can set 8 channels, except the uplink and downlink frequencies are fixed, the CTCSS and color code of the uplink and downlink can be set according to your needs. The bandwidth can be set to wideband or narrowband. The TX power can be selected to be high or low, and the mode of channel works can choose analog (FM), digital (DMR), or digital and analog (FM/DMR). When the FM/DMR mode is selected, the repeater can forward to transmit the information of digital or analog walkie talkie.

Easy to Plug in and Set Up: The RT97P Base Station has a built-in duplexer, allowing TX/RX using only one antenna.

Comes with LCD Display: The easy-to-read screen shows important information like frequencies and CTCSS/DCS codes. You can easily change channels or settings with the simple buttons.

Portable Radio Repeater: RT97P has a compact structure. The longest side is only 31 cm and the weight is less than 3 kg. 

Multiple Power Options: The RT97P can be powered by DC12V~24V, car power, or a solar battery, making it perfect for both fixed setups and mobile use.

User-Friendly Interface: The RT97P is designed to be easy to use, with a straightforward programming interface. This allows both advanced users and beginners to set it up without a steep learning curve.

Rugged Durability: Built to withstand outdoor conditions, the RT97P is a rugged option for users who need reliable performance in various settings.

Support Mixed Mode: It supports mixed mode, which means one channel can use the same frequency to communicate with analog radio and digital radio. 

Customizable Frequency: Besides the UHF and VHF stock frequency versions, RT97P also supports customization. The TX and RX frequencies can be customized between UHF (400-470 MHZ) or VHF (136-174 MHZ), Offset: ≥5MHz and ≤12MHz. You can send your customization requirements based on your handheld radio working frequencies. It takes around half a month to customize frequency.
