How to choose the right DMR radio?
There are many DMR radios on the market with different appearances and different functions. Do you know how to choose the right DMR radio to meet your using requirements and make the coest lowest?
Steps to choose the right DMR radio:
1.UHF or VHF? Or dual band UHF and VHF?
This is the first step for us to choose the correct DMR digital radio. To find out the answer to this question, first of all, we must understand our use requirements, that is, the use environment of the walkie-talkie.
If the radio will mostly use in outdoor activities,like hiking, riding, Racing, hunting and other open environment, there are not many obstacles, then we recommend you to choose the VHF frequency range, like Retevis RT3, RT8, because the VHF frequency range of radio has strong diffraction ability, which is very suitable for open outdoor environments. It can make the radio talking distance reach the best in an open environment.
If the radio will mostly use in door, like city,buidling, warehouse, school, church, hospital, production factory, etc,.the environment that have many obstacles, then we recommend you to choose the UHF frequency range, like Retevis RT50, RT80, RT40, RT53, RT83, because the UHF frequency range of radio has strong penetrating power ability, which is very suitable for city environments. It can make the radio talking distance reach the best in such environment.
which frequency should we choose for your DMR radio?
While, if your use scene needs to be changed, that is you will sometimes use it in open environments, such as outdoor travel, or in urban areas, such as office buildings, then retevis radio solutions recommends UHF/VHF dual band DMR radio to you,like retevis RT82 RT84 RT3S RT52,Ailunce HD1, which can meet the outdoor and urban environment at the same time.
2. How big power should you choose?
As we know, not only DMR radio, but also analog radio, all have different power, from 0.5W to 10W, 0.5W, 2W, 5W, 8W, 10W, Do you also have this kind of confusion, which one should I choose? The choice of which power DMR Radio also depends on your needs. The most important thing is your demand for the call distance, combined with the influence of the use environment on the call distance, and then choose the DMR Radio with the appropriate power.
For example, if you use it in a warehouse, the call distance is required to be 2km. If there are not many obstacles in the warehouse, then you can safely choose a 2W DMR radio, such as Retevis's RT40 FRS license free DMR radio, RT53. However, if there are many obstacles in the warehouse, which will affect the signal of the walkie-talkie, then you can choose a 5W walkie-talkie from retevis, such as Retevis RT3 RT8 RT80 RT52 and so on. If your talk distance is 5km, then you need to choose a 10W high-power radio, such as Retevis's RT81 RT50 RT83 and so on.
Therefore, to select the appropriate power, you must first determine your call distance requirements, and secondly refer to the use environment of the DMR radio.

3.Channel
The number of channels, how to choose a suitable DMR radios so that it can meet my requirements for the call numbers?
In the description of DMR radios, we often see 16 channels, 42 channels, 3000 channels, and even more. However, for actual use, it does not mean that the more channels, the better. You need to remember that the right ones it's the best. So, how do we choose the appropriate number of channels? Still the old saying, start from the needs.
For example, DMR Radios are only used for a small group of more than a dozen people. Then, you can choose a DMR radio with a relatively small channels. For example, Retevis RT43 only has 40 channels, and retevis RT40 has only 48 channels. Retevis RT81 has only 32 channels, these models are very suitable. And if you are a ham or manager and need to keep in touch with a lot of people, you can choose a DMR radio with a large number of channels. For example, RETEVIS RT52 has 4000 channels, and Ailunce HD1 has 3000 channels. They are all very high quality DMR radio.
4.Digital system compatibility
Many users who have used Motorola radios before often have this question. If I use a DMR radios of other brands, can I use it with my existing Motorola radios?
To know whether the walkie-talkie is compatible with Motorola's walkie-talkie, you must first understand the key point: DMR TIERS.
WHAT ARE DMR TIERS?
Digital Mobile Radio (DMR) has three defined tiers that allow manufacturers to create equipment for different types of customer. Some customers may only require a simple system where each radio talks to every other radio, whereas emergency services may require country-wide networks with encryption and remote programming. We usually see "Compatible with Motorola Tier Ⅰ&Ⅱ" descriptions in online radio listings,do you know what is Motorola Tier?
DMR Tier was founded by Motorola, divided into three, they represent different digital signal processing modes, only the mode is consistent, can be compatible with each other and talk to each other, like retevis RT50, Using TDMA technology, designed with Tier II,AMBE++ vocoder, compatible with mototrbo etc. DMR two way radio.
Therefore, to choose a matching DMR radio, first we need to confirm whether it is compatible.
Here Retevis solutions have a great model DMR radio recommended,it is Retevis RT81,10 reasons to choose Retevis RT81 DMR radio:
