功能很多，毛病不少。 FT5DR的功能堪称丰富。真双守、双信道指示灯、全段接收、频谱图；APRS、C4FM、GM/X……以及信道存储归纳（存储库、扫描跳过、PMS编程扫描）。然而FT5DR丰富的功能并没有一个简洁快速的交互；拿到手后，需要翻阅基本手册、高级手册，对于特定功能（如APRS、GM/X）还有专门的手册。在最初上手时，一定会花掉很多时间来学习。但是机器也有不少缺点，比如昂贵的编程线（虽然某鱼上有100出头的DIY线）竟然不支持固件升级；信道名几乎不支持汉字写频（国内销售的版本在写频软件上无法输入日文汉字；而日版的写频软件不能读取国行版机器的设置文件），只有用日文输入法输入汉字。以及我和其他友台都有遇到过烧屏的问题：用久了以后屏幕留下残影（可以看我之前发的帖子）。

以及，机器的电池相当不够用。座充最多只能充电到8V的样子😭5DR的APRS解码能力不行，但凡信号弱了一些或者强度有变化就很难解码。5到10分钟的通联（5W发射）场景下机器的发热量很大。

你是什么玩法关键，如果只聊天我还是建议摩托罗拉捏

@"BD8DLV"#p36307 我想入手一个真的会有烧屏的情况吗？

@"BD8DLV"#p36308 实在不行我就入6R 了

不知有没人专门对比过同样是有核准号的DMR手台——UV-4R和AR-55A。我在这两者之中选择了AR-55A。主要是看到成都M哥推荐，且定制方世纪金宇作为QSL卡片局的1区分局也比较有名气。用下来发现，AR-55A的软件用户体验设计实在不过关，很多菜单的组织逻辑不合理，输入频率的操作也不按一般业余手台的习惯设计。不过好在基本的模拟和数字通信能力还不错，功率足。自带中文输入法，频道分区存储之类的功能也实用。作为入门级DMR设备，也是个不错的选择。

网上的视频来看有些人的会烧屏，但我的还没烧。不如先考虑一下需求是什么？ YSF设备的优点： 1. 数字对讲机中最好的音质，需要手动开启该模式。（与P25相同，八重樱作为摩托骡拉长期合作伙伴的含金量） 2. 数字模式中最远的可用距离。在AMBE+2编码的基础上额外增加了更多校验数据实现的。与音质模式冲突，不过也就是降低到DMR的水平，不太可能降低到D-Star的程度。 3. 八重洲的中继台更常见。 4. 群组模式，要求全员都使用YSF设备，成本不菲。 5. 有核准，虽然TH-D74/75在很多方面上都更好，但是没核准也不在大陆发售。 FT-某D的优点（部分条目得排除1D的两台）： 1. 完整的APRS支持。别笑，隔壁Icom把APRS全改成D-PRS了，国内更没法用。 2. 短波收音机支持。 3. ~~不需要热点盒子~~为什么划掉呢，因为国内没人用。D-Star的设备反而真的可以丢掉盒子。 4. 直接在设备上**_搜索_**和加入反射器/聊天室。（大触摸屏最有用的一集） 5. SD卡写频。 6. 触摸屏……但是很多人其实更喜欢键盘。 7. 双接收电路，不过这种高端业余机型都是双接收，推测原因是为了尽可能的保持与AX.25或D-PRS网络的联系。 FT-5D的优点 1. 蓝牙耳机支持，但是传统蓝牙。 2. 快拔背夹。 3. 至少比另外两家的竞品便宜。缺点： 1. APRS解码对信号质量要求较高，解码失败的几率要比同类设备高。 2. 无法接收单边带信号。不过竞争对手里也只有TH-D74/75支持。 3. 祖传的日本顽固不化老头式人机交互界面。 4. 不能USB充电，使用超级慢速DC充电接口，如要快充，请买座充。 5. 日本顽固不化老头才会喜欢的诡异数据接口。 6. 四本说明书，有的功能还没讲明白你敢信？ 7. 电池用的真的很快。 8. 没有中频输出……至少D75有。优点部分如果只有第一组戳中了的话，不如买70D或者二手1XD。至于第二组，虽然2D、3D也行，但不如直接上到5D。如果对优点都不在意，或者缺点更无法忍受的话，还是看看友商吧，或者看看模拟机型也可以。

@"htl"#p36315 有，烧屏。而且外壳有裂的通病，后期好像是改良了，不确定

@"htl"#p36315 即使开启了无操作息屏，由于屏幕本身还是在显示（只是亮度很低），长时间守听（二三十个小时）之后就会有烧屏痕迹了：在全灰色背景图案下，常用的一些界面元素会留下残影。

@"BloodBlade"#p36324 说得很全面~

What are your thoughts on the Yaesu FT-5DR?

htl

I'm looking to purchase

BD8DLV

It has many functions, but also several drawbacks.

The FT5DR offers a wide range of features. It includes true dual-watch, dual-channel indicator lights, full-band reception, and a spectrum analyzer. It also supports APRS, C4FM, GM/X, as well as channel storage (including a database, scan skipping, and PMS programming). However, the FT5DR's extensive features don't come with a simple or intuitive interface. After receiving the radio, users need to consult the basic manual, advanced manual, and specialized manuals for specific functions such as APRS and GM/X. This will require a significant amount of time to learn.

However, the machines also have several drawbacks. For example, the expensive programming cables (although DIY cables costing around $100 are available on some platforms) do not support firmware upgrades; the channel names almost do not support writing Japanese characters (the Chinese versions of the software cannot input Japanese characters in the writing mode; while the Japanese version of the software cannot read the settings file of the Chinese version machines). Only using the Japanese input method can input Chinese characters. In addition, I and other friends have also encountered the problem of screen burn-in: after prolonged use, a residual image remains on the screen (as you can see in my previous posts).

htl

BD8DLV I want to buy a screen that definitely has burn-in.
Is this the situation?

BD8DLV

Also, the battery life of the machine is quite short. The charging station can only charge it up to around 8V.😭The APRS decoding capability of the 5DR is poor. It becomes very difficult to decode when the signal strength is weak or fluctuates. The machine generates a lot of heat in scenarios with continuous communication (5W transmission) lasting 5-10 minutes.

htl

BD8DLV If that doesn't work, I'll buy the 6R.

BI1JNP

What are the key features of your approach? If it's just about chatting, I still recommend Motorola.

BI4PMQ

htl Yes, there was a screen burn issue. Also, the common problem with the case is that it cracks. It seems like they made some improvements later on, but I'm not sure.

BD8DLV

htl Even with the "no-operation sleep" feature enabled, due to the screen still being active (albeit at a very low brightness), prolonged inactivity (twenty to thirty hours) can result in burn-in: common interface elements on a full gray background will leave afterimages.

BloodBlade

According to videos I've seen online, some people experience screen burn-in, but I haven't experienced that yet.

Instead, let's first consider what the requirements are?

Advantages of YSF equipment:

The best audio quality in digital radios requires this mode to be manually enabled. (This is the same as P25, and highlights the value of Eight Cherry as a long-term partner with Motorola.)
The furthest usable distance in the digital mode. It adds more check data on top of AMBE+2 encoding. This conflicts with the audio quality mode, but only reduces it to DMR level, and is unlikely to reduce it further to D-Star level.
Yaesu repeaters are more common.
Group mode requires all members to use YSF devices, which can be expensive.
While TH-D74/75 has been approved, it's not yet officially certified and is therefore not available for sale in mainland China.

Advantages of FT-Some D (excluding two units from the 1D series):

Full APRS support. Don't laugh, but my neighbor's Icom has completely switched to D-PRS, and it's even worse here in China.
Supports shortwave radio receivers.
~~No hotspot box required~~Why are they being discarded? Because no one in China uses them. The D-Star equipment can actually be thrown away without a box.
Directly on the deviceSearchAnd join the reflector/chat room. (The episode with the largest touchscreen was most useful).
SD card with a write-frequency function.
Touchscreen... but many people actually prefer a keyboard.
Dual receiver circuit, but this high-end amateur radio equipment uses a dual receiver design. The likely reason is to maintain as much contact as possible with AX.25 or D-PRS networks.

Advantages of FT-5D

Bluetooth support is available, but it uses traditional Bluetooth.
Quick-pull back clamp.
At least it's cheaper than the competing products from the other two companies.

Disadvantages:

Decoding APRS requires high signal quality, and the probability of decoding failure will be higher than that of similar devices.
It cannot receive single-sideband (SSB) signals. However, only the TH-D74/75 supports this feature among competitors.
Traditional Japanese stubborn and unyielding human-computer interface style.
It cannot be charged via USB; it uses a very slow DC charging port. If you want faster charging, please purchase a separate charger.
This strange data interface is perfect for stubborn, old-fashioned Japanese users.
Four manuals – are you really going to believe that some of the features haven't even been explained?
The battery drains very quickly.
There is no medium-frequency output… at least D75 has one.

If only the first group of targets is hit, it's better to buy a 70D or a used 1XD instead. As for the second group, while 2D and 3D are also viable options, buying a 5D directly would be preferable.

If you don't care about the advantages or find the disadvantages unbearable, then consider looking at products from other vendors, or even a simulator.

BD8DLV

BloodBlade It was very comprehensive.

htl

BloodBlade Should I not get an MMVDM box?

deepweb

What are your thoughts on the iCOM ID52 Plus? If I'm not buying from 5DR, should I just go with iCOM instead?

BD8DLV

deepweb I just got this radio, and here are my initial impressions: The operation and interface are much better than the FT5DR. The radio doesn't require a separate write-in cable; a single microUSB data cable is sufficient for both charging and writing in. However, it lacks APRS (only has a DRPS mode based on DSTAR), and its reception range is limited (e.g., only A band can receive aviation). The screen is full color, but the screen quality is average, and it's not touch-screen capable. Changing frequencies requires constantly turning the dial.
I haven't encountered any other issues yet; this is just for reference purposes._😊

BG2EFX

Get a high-quality 2D solution. Optimal solution.

BG5BLI

The burn-in issue seems to affect all screens of this type, eventually. After all, there's only so much content that can be displayed, and areas that are constantly on will eventually develop "burn-in." Mine has already developed it.😂

BloodBlade

htl It's neither, nor, because without the box, it can currently only connect to the Wires-X network. This network is not directly connected to YSF or BrandMeister; instead, it can only be joined through a bridging method.

The BM46001 was previously connected to the Wires-X bridge, but it appears to have become inactive or been shut down. Currently, there are no active nodes within China, although there are many active nodes in other countries.

Also, the developer of MMDVM stated that to directly integrate the 5D with the MMDVM software, someone would need to provide him with the WireX software connection protocol. This means either Yaesu would have to make the protocol public, or someone would have to reverse engineer and crack it.

BI1UHW

Using the 5dr is still challenging, for example, you need to read several manuals to understand the basic usage methods. Some require you to re-read them when you encounter or think about them. The menu structure is also very unnatural. After using it for almost six months, I have identified a few issues that affect daily use:

The "Tonglian" device consumes a lot of power; approximately one 20-minute session uses up one full battery.
The original battery has self-discharged. Similarly, after leaving the UVK6 battery for a while, the 5DR no longer works, but the UVK6 is still almost fully charged. Although there is a difference in capacity, it should not be this extreme.
The accessories are troublesome; you need to buy a charging cable, and the official price is close to 300 yuan. You also can't use it to upgrade the firmware.
Charging is inconvenient because it only uses the DC port, not USB/Type-C/microUSB ports. It also charges slowly, and a fast charger needs to be purchased separately.
It only supports Japanese and English, and there are also length restrictions on the write-in names. As we all know, both English and Japanese require a significant amount of characters to express the same meaning.
High-brightness screen viewing can cause burn-in, but mine disappeared after a while. I'm not sure if it was because I didn't use it at high brightness for long enough.
High-power, long-term communication resulted in a rapid temperature increase. However, the testing was conducted during the summer months, and the winter conditions were not tested. Nevertheless, it has been proven that using UVK6 under those conditions did not cause burns like 5DR.

BD8DLV

BI1UHW Yes, the 5DR does generate a significant amount of heat. However, point five: while it's possible to input Japanese characters using a Japanese input method to specify channel names, this is very cumbersome for those without prior knowledge of Japanese.

BG4XSG

I've started using the ysf service on my mmdvm, but isn't there a c4fm-46004 server that I could also use? And does it also have a weekly attendance check?
