哪种协议用的人多一些？另外DMR的中继台能不能转发文字信息？

取决于你本地中继台都用什么

我感觉DMR人更多一些，但是DMR你还得买盒子，机器和盒子加起来应该得六七百，不过有更实惠的方法：拿刷了OpenGD77的DM1701当中继，能五百以内玩

本地中继用啥你买啥，本地么有数字中继买dmr的，设置mmdvm方便一些

本地哪个玩的多买哪个不过要做好数字台一耳劝退辣鸡声音的准备

第一点：你要确认你的城市有什么中继，对应中继购买对应的数字对讲机。第二点：MMDVM盒子是个必备品，可以将数字模式极致化，DMR和C4用户都能用第三点：盒子可以自己手搓（树莓派+双工板+小屏幕），不想动手就买成品，推荐BH4ERY的第四点：DMR手台品牌多，便宜的100-300，贵的也有上千的，根据自己情况选购 DMR国产热门品牌：宝峰、如意通、海能达、任意通等 DMR国际热门品牌：MOTOROLA （可以先入手一个二手的摩机如8268、8260、6550等也就300左右）备注：需要注册一个bm账户（虽然DMR已经有国服了，但是建议还是注册一个）

@"BA4JWC"#p89321 线下使用看你本地中继。如果中继未联网或者没有中继，那不同模式的设备可以通过热点的交叉模式功能接入其他模式的网络。因此不用根据使用人数来选择，看你钱包就行。一般是DMR最便宜，人数也最多；YSF明显高一档位；然后D-Star更高一点。建议先[用手机或者电脑试试](https://docs.hamcq.cn/pages/52354c/#没有数字对讲机)再说，毕竟相比模拟真的比较贵。而且对于不喜欢嚼破布的人来说不怎么值。 @"BG5VMD"#p89340 以设置方便程度来说的话，怎么看都是YSF>>D-Star>>>>>DMR。热点设置方面，[YSF选了反射器直接就能用](https://docs.hamcq.cn/pages/d3a82e6/#系统融合-ysf-c4fm-2)，[DMR至少要设置ID、网络、ESSID、服务器和色码才能开始用](https://docs.hamcq.cn/pages/d3a82e6/#dmr-2)。考虑到楼主是刚入坑数字机型，那还得走注册流程。[DMR不但要拍摄身份证件来注册ID，还得在对应网络注册](https://docs.hamcq.cn/pages/d3a82e6/#dmr)；[D-Star直接填个呼号就能注册，通过之后点几个勾就能正式启用](https://docs.hamcq.cn/pages/d3a82e6/#d-star)；YSF更是连注册都不用。

@"BA4JWC"#p89321 对了，漏了D-Star的一个特性，较新的D-Star设备借助手机或者电脑就能联网，不是必须要用热点。

DMR是欧美的的数字标准，机子从便宜到贵的都有，摩托罗拉用的就是DMR； C4FM是八重州专用数字标准，C4FM不能和DMR互通。其实演变成了选品牌了。

@"BI3QAC"#p89373 不过有MMDVM盒子的话其实也能是想C4于DMR的互通

@"bh1cqz"#p89378 咱说的互通是直接通讯。MMDVM盒子走的是网络，和公网机没差别。

I'm planning to get into digital radio, but I'm not sure whether to buy a DMR or a C4FM system.

BA4JWC

Which protocol is used by more people? Also, can DMR repeaters forward text messages?

BloodBlade

BA4JWC For offline use, please refer to your local repeater.

If the repeater is not connected or there is no repeater, then devices in different modes can access other networks using the hotspot cross-mode function. Therefore, you don't need to choose based on the number of users; just consider your budget. DMR is generally the most affordable and supports the largest number of users; YSF is a higher-end option; and D-Star is even more advanced.

We recommend that you firstTry using your phone or computer.Furthermore, considering the cost compared to real simulations, it's not really worth it for those who don't enjoy chewing on fabric.

BG5VMD Considering ease of setup, YSF is clearly the better option.>>D-Star>>>>>DMR.

Regarding hotspot settings:YSF chose a reflector that could be used directly.，To start using DMR, you must at least configure the ID, network, ESSID, server, and color code.。

Considering that the original poster is new to digital devices, they will still need to go through the registration process.The DMR system not only requires you to provide identification documents for registration, but also requires registration on the corresponding network.；With D-Star, you can register simply by entering your call sign. After registration, just check a few boxes to officially activate it.; YSF doesn't even require registration.

BloodBlade

BA4JWC By the way, I forgot to mention one feature of D-Star: newer D-Star devices can connect to the internet using a mobile phone or computer, rather than requiring a hotspot.

It depends on what repeaters your local repeater sites are using.

BI3SVM_Rinko

I feel like DMR has more users, but with DMR you still need to buy a radio and accessories, which would probably cost around six or seven hundred yuan. However, there's a more affordable option: using a DM1701 with OpenGD77 firmware as a repeater, which can be purchased for under five hundred yuan.

Watermelon

BI3SVM_Rinko 100 x dual-function boards + 100 x Raspberry Pi Zero 2 W + 200 x UV4R or 1701

BG5VMD

If you need a local repeater, buy whatever you need locally. There are no digital repeaters for sale locally that use DMRS; setting up MMDVM is more convenient.

BG4ILW

The easiest way to set up an MMDVM is with C4FM, while DMR is the least convenient.

BG5VMD

BG6UFA

Which one is more popular locally? Buy that one.

However, be prepared for the possibility of digital audio canceling out unwanted sounds.

BI3QAC

BG6UFA I'm using the TYT MD-UV390 PLUS, and the sound quality is quite good. It has no difference compared to the analog mode. Also, Motorola uses DMR digital mode.

First: You need to confirm which repeaters are available in your city, and then purchase the corresponding two-way radios for those repeaters.
Second point: The MMDVM box is a must-have, allowing you to fully utilize digital modes and is compatible with both DMR and C4 users.
Third point: The box can be assembled yourself (Raspberry Pi + dual-screen board + small screen), if you don't want to assemble it, buy a finished product. I recommend BH4ERY's.
Fourth point: There are many brands of DMR handheld radios available, ranging from affordable models costing between $100 and $300 to more expensive ones that can cost over $1,000. Choose the one that best suits your needs.
Popular domestic DMR brands: BaoFeng, Ru Yi Tong, Hytera, Any Tone, etc.
Popular DMR brands internationally: MOTOROLA (You can start with a used Motorola, such as the 8268, 8260, or 6550, which cost around $300)
Note: You will need to register a BM account (although DMR already has a domestic server, it is still recommended that you register one).

BA4JWC

BloodBlade It seems like DSTAR is primarily available through ICOM.

BI3QAC

DMR is a digital standard used in Europe and America, and you can find radios ranging from inexpensive to high-end models. Motorola uses DMR.
C4FM is a proprietary digital standard for the Eight Provinces region, and C4FM cannot be used with DMR.
In reality, it has become a matter of choosing a brand.

bh1cqz

BI3QAC However, if you have an MMDVM box, it can also be used to communicate with DMR systems.

BI3QAC

bh1cqz When I say "intercommunication," I mean direct communication. The MMDVM box uses a network connection, which is the same as using a public network connection.

luckyum

I'm using a dual-mode handheld radio that supports both UV and DMR. It's affordable, and the sound quality is good. When connected to the local DMR repeater, it allows me to communicate with anyone in the area via simplex or group calls.
Also, I want to buy an MMDVM box so that it can connect to the internet and communicate with other users across the country, enabling both single-channel and group calls.
Yaesu - at least 1000
You can buy high-quality domestic handheld radios for around 500 RMB, and even ones costing around 200 RMB are usable.

BA4JWC

Okay, are there any DMR/C4FM repeaters available for testing in Jinan?

BG4IJK

BA4JWC DMR: BR4JH 438.8875 -6.6 slots, 2-color code, full call
C4FM: Garden Suburb 439.1875 -6.55

I heard that someone in Zibo was using C4.

bh1cqz

BA4JWC 目前看济南的DMR中继比较多，上次去济南，带的3dr，参加了黄河的台网签到点名。

BloodBlade

BA4JWC Icom only developed D-Star under the commission of JARL, but in reality, other brands can also produce D-Star devices. For example, the top-of-the-line handheld radio TH-D75 is a Kenwood product.

BG5TOX

Buy all of them.
