入门B证选哪个几个好？要求方便户外架台也可以做为基地台使用，最好有内置天调，性价比高，想一次性投入到位，保值率高的机器。求各位老HAM推荐，谢谢！

经豆包查询：1. 价格：FT-891价格更为亲民，最低4880元左右。FT-710价格较高约7880元。 2. 性能：FT-710采用SDR架构。接收方面，灵敏度和小信号信噪比表现较好，频谱图分辨率、刷新速度等一流。FT-891采用中频DSP架构，配备32位DSP芯片，NR降噪功能效果提升明显，语音接收性能较好，能接近FT-DX1200的水平。两者都能输出100W功率，FT-710电压适应范围更广，最低9.6V还能发射，输出功率约75W。 3. 便携性：FT-891尺寸为152×52×218mm，体积小巧，重量较轻，更适合便携使用。FT-710尺寸约为239x80x247毫米，重量约4.5千克，相对较重，便携性稍差。 4. 操作界面：FT-710配备4.3英寸TFT彩色触摸屏，具有三维频谱流，操作直观，显示信息丰富。FT-891通常为传统按键配合显示屏的设计，操作方式较为传统，在设置和查看信息时可能不如FT-710便捷。

找豆包不如找几个用户多聊聊感受

先看看家里的电磁环境再说，电磁环境好肯定 710 基地台，但如果电磁环境不好同时很难架设天线，你确定要背负着 4.5 公斤的基地台野架么😂891 的话 1.9 公斤，再带个外置小天调足够了

@"BA4TEK"#p67760 野外架台的话我用710也可以吧？

@"BA7NNC-JOE"#p67776 这个是如何操作实现的？

@"BG5EYK"#p67782 FT891+SDR天线切换器+RSP+电脑SDR Console 全联动，全同步，按PTT发射同步断开SDR保护，软件自动RF MUTE 反正现在在家用，我再也不羡慕7300 710的频谱了 🤣

For a beginner, which handheld radios are recommended? I need one that is convenient for outdoor use and can also be used as a base station. Ideally, it should have built-in SWR (Standing Wave Ratio) measurement, offer good value for money, and allow for a significant initial investment with high resale value. I would appreciate recommendations from experienced amateur radio operators. Thank you!

891 does not have a sky control.

Let's also consider a longer-term perspective.

7300 710

BH4HKF

According to the information obtained from Doubao: 1. Price: The FT-891 is more affordable, with a price of around 4880 yuan. The FT-710 is more expensive, priced at approximately 7880 yuan.

Performance: The FT-710 uses an SDR architecture. In terms of reception, it offers excellent sensitivity and signal-to-noise ratio, with top-tier spectral display resolution and refresh rates. The FT-891 utilizes a mid-band DSP architecture with a 32-bit DSP chip, resulting in significantly improved noise reduction performance and good voice reception capabilities, approaching the level of the FT-DX1200. Both can output 100W power; however, the FT-710 has a wider voltage adaptation range, allowing it to operate with as low as 9.6V, with an approximate output power of 75W.
Portability: The FT-891 has dimensions of 152×52×218mm, making it compact and lightweight, ideal for portability. The FT-710 measures approximately 239x80x247mm and weighs about 4.5kg, which is heavier and less portable.
User Interface: The FT-710 features a 4.3-inch TFT color touchscreen with three-dimensional spectrum display, offering intuitive operation and abundant information display. The FT-891 typically uses a traditional button layout combined with a display screen, making its operation more conventional. In terms of setting and viewing information, it may not be as convenient as the FT-710.

Have you considered using the FT891+ as an external unit?🤪

Bi4KKF

It's better to talk to a few users and get their feedback than to just look for "doubao."

BA4TEK

Let's first assess the electromagnetic environment at home, and if it's good, then a 710 base station would be suitable. However, if the electromagnetic environment is poor, it will also make it difficult to install an antenna. Are you sure you want to carry around a 4.5 kg base station?😂With the 891, it weighs 1.9 kg, and an external small antenna would be sufficient.

BG5EYK

BA4TEK Regarding outdoor mounting brackets, could I use a 710 as well?

BA4TEK

BG5EYK Of course, it's just twice as large and heavy.

BG5EYK

BA7NNC-JOE How is this implemented?

BA7NNC-JOE

BG5EYK

FT891+SDR antenna switch + RSP + computer SDR console

Full synchronization, full compatibility, PTT-triggered synchronized disconnection of SDR protection, automatic RF mute software.

Anyway, since I'm using it at home now, I no longer envy the spectrum of the 7300 or 710. 🤣

BG4IJK

891: Lightweight (compared to other models), making it easy to carry and fit in a backpack.

Regarding the issue of "sky adjustment," I bought one for 891 yuan, but it's completely useless.

As for not having a spectrum chart, the common frequencies are those, and over time, you naturally become familiar with them. Turning a large knob is also one way to find a specific frequency.

+1 I also bought a Tian Dao, but haven't used it much. It can achieve natural harmonic resonance to within 1.5 with both GP and V modes. What else do I need?

BG0GAA

It has an integrated APRS (Automatic Packet Reporting System), and of course, it's the Icom PMR-171.

There's no single "best" option; it depends on individual preferences, needs, and habits. Old Ham said the 7300 is good because it has a wide user base, which was likely due to his personal preference at the time.
As a Yaesu equipment user (who has not used an ICOM)
The 710 is a newer model. If you prefer a traditional architecture, the 891 is your best choice. For shortwave and UV combined operation, the 991A is ideal. If you're using a pure SDR architecture for shortwaves, then the 710 is a good option. If you want to go the QRP route, consider the ICOM-705. However, the Yaesu model hasn't been released in China yet, and it's also quite expensive!

BG6HFD

If you're just starting with a B license, focusing on shortwave radios is the way to go. Currently, the 710 offers the best value for money, and I recommend it to all other HAMs. Compared to the 7300 and 891, it has more up-to-date technology that's better suited for urban users. Compared to machines like DX10, it's lighter and smaller, making it ideal for portable use. It includes a built-in antenna tuner, but there's no guarantee of its resale value. Most enthusiasts who are buying new radios will choose the 710.

BG5EYK

BG6HFD What are the technical differences between the 7300 and the 710? What is the price difference?

BG6HFD

BG5EYK The prices of the two models are similar, with the domestic versions priced around 8k. You can find specific prices by searching on Taobao. In terms of technology, both models use an SDR architecture, but the 710 adopts new technologies such as dual ADCs to improve the traditional SDR's susceptibility to interference, and has a wider dynamic range. The ranking list from http://www.sherweng.com/table.html shows that the 710 is ranked third, behind the DX10 and DX101, while the 7300 is ranked 25th. This doesn't mean the 7300 is bad; it simply means that the 7300 has been on sale for nearly 10 years, and there is a gap in performance compared to newer models.
After personal use, this generation of Yaesu's "DNR" digital noise reduction is very effective. It almost completely isolates the user from noise, which is very helpful in environments with a lot of interference.

BG5EYK

BG6HFD It seems that getting the 710 would be a better option after all.

BG6HFD

BG5EYK 是的，不过只用语言叙述有些苍白无力，我个人建议您可以在b站等平台搜索一下实际使用的视频，对您了解机器能更有帮助
