Please provide insights on the pros and cons of the ICOM-7300 and the FT-710.

我想入手一台短波电台现在在icom7300和ft710之间来回徘徊，我想听听各位大佬对这两款设备的见解

BG7NOD

Both are available. If you have the 7300 MK1, choose the FT-710. If you have the 7300 MK2, choose the 7300 MK2.

I'm currently using the 7300, but I often experience strange errors when connecting it to my computer via serial port. The built-in tuning function is also not very user-friendly. If I had to choose again, I would definitely go with the FT710. Buying a new one is always the best option.

BG7NOD

BA4RCM I have also experienced serial port issues when using the 710.😂

BA4RCM However, in my and a few other repair friends' actual experiences, the 710 is by far the most prone to serial port failures! The 7300, on the other hand, has almost never had any serial ports fail.

BA4RCM I used the 7300 with 4 antennas, a DP and two end-fire antennas plus a GP, and the serial connection was very stable. I didn't experience many instances of the serial port being completely unusable (which happened occasionally over the course of a year), so it seems that antenna quality and interference mitigation measures are very important.

I've reviewed this question several times, from when I first considered buying the machine to after I actually purchased it.😂To summarize, I don't think there will be a significant difference in performance between the two machines. The 710 seems to have better reception capabilities, while the 7300 has a better user interface. However, neither reaches a top-tier level. As for the rest, it depends on your personal preferences: Do you have any brand biases? Do you like the appearance (ID design, button layout, port placement)? Can the accessories meet your needs? If you need specific recommendations, please describe your thought process.
Of course, if I were simply asked to choose, I would select the 710.

If you frequently switch between SSB, CW, FT8, and other modes, especially if you occasionally experiment with SSTV or RTTY, the switching operations on ICOM and Yaesu radios are truly frustrating and require a lot of patience.

BG7NOD

I'll just give you a picture; I won't say anything else, because if I do, I'll get yelled at.

BD4WCL

BG7NOD All SDRs are like this.

BI7ALG

BD4WCL A frog in a well

BG7NOD

BD4WCL Come on, refute it!😂

BG7NOD

BI7ALG Haha haha…

BD4WCL

BI7ALG "Waterfall" or "comb filtering" is a common issue with SDR radios, whether using audio sampling or direct RF sampling. Some devices (such as certain models from ICOM and Yaesu) use software algorithms to minimize the effect; if there are no strong interfering signals nearby, or if the pre-amplifier is not enabled (or has low gain), waterfall effects are less noticeable.

Regarding the common observation that DX10 doesn't exhibit "cross-talk" (interference between different broadcast channels), this is actually due to its use of a mixed sampling method, which provides better suppression of such interference.
If you have a different opinion, please share it, but avoid being sarcastic or critical of others.

BD4WCL

BI7ALG 当然如果ADC有足够高的动态范围（远不止常见的16bit 24bit之类的，要远高于这个）就不会串广播

传统架构的机器在前端有模拟前端滤波与衰减，串广播的现象就会基本没有（我们平常通讯信号（包括广播）也没有那么高的功率）

总之，串广播所有电台都有，只不过SDR因为是先转换为数字，前端滤波会差一点，会更明显，就看厂商软件的情况。

BD4WCL

BG7NOD What? What's there to refute...? There's nothing good to refute.

BG6HFD

The serial port issues are likely due to interference, and may not be directly related to the device itself. The device's structure might make it more or less susceptible to interference in certain situations.
I have used the end-fed V-shaped loop GP, and it was very susceptible to interference with the serial port, even causing the mouse to disconnect. The horizontal orientation of the GP sometimes caused interference when fishing; adjusting the antenna's resonance and ground wire usually helped. I haven't experienced much interference with the end-fed and positive V configurations.
Currently, effective solutions being tested include: using shielded cables with magnetic rings for serial connections, which significantly improves interference resistance; connecting a choke to the radio's RF port to suppress interference, and also recommending that both computers and radios be properly grounded.

Don't ask me, just say that the 7300 is too ugly.

BG7NOD

BloodBlade Personally, I think the screen resolution is too low. The new version still has such a low resolution; it would be much better if it could support 800x480 or higher.

The after-sales repair service for ICOM is in Japan. The after-sales repair service for YAESU is in Suzhou.
