icom的**ic-7300**可以说是许多人的梦中情台，也是性价比极高的一款入门级SDR架构电台，许多HAM在购买7300时会遇到不同版本间有许多的差异的问题而难以抉择，希望社区的大佬们能给小白科普一下7300的不同版本间究竟**有何区别**？区别**是否影响**实际通联？以及影响实际通联到什么**程度**？

推荐购买带国内核准标签的。可以上执照。一般来说从频率覆盖角度来说，，美＞欧/国行＞日。

区别只有波段不同，以及附件稍有区别，波段不同影响通联，比如日版的160米 80米欧版的80米和中国不太一样，发射不连续。

回来自己拆几个小东西。。大家就都一样了

@"BH6KWC"#p2704 这个可以直接使用电台的MENU>SET>Function>User Band Edge就可以直接修改，说明书上也有修改方法

欧版电源线多一个滤波器具体效果如何我没见过我的是日版的另外就是这机器快停产了现在买来得及后续新型号估计也不便宜

@"BD3PSX"#p43142 改完配置里面那几个二极管位置调节才有效

日版不能扩频，有些在国内可以用的频段它没有。主要都是频段差异，欧版美版扩频后没差别，国行没了解。美版大约8800，欧版8500，日版就很便宜了，最低的都不到7000。

@"HeyCharlie"#p43153 不懂别乱讲哦 7300不分任何版本改动二极管矩阵即可扩频你说的那应该是ic705

美的用$买日版用冈买

@"Syryia"#p43170 那是我反了，也不至于不懂吧？

Could a knowledgeable person please advise me on the differences between the European, American, Japanese, and domestic versions of the Icom 7300 radio?

icom'sic-7300It can be considered the dream SDR radio for many, and a very cost-effective entry-level SDR architecture radio. Many HAMs encounter numerous differences between different versions of the 7300 when purchasing, making it difficult to choose. I hope that the community's experts can provide some basic information about the differences between the various versions of the 7300 for beginners.What are the differences?? DifferenceDoes it affect?Is it actually possible to achieve real-time communication? And what factors influence this?Degree？

I recommend purchasing those with domestic approval labels. You can obtain a license. Generally, from the perspective of frequency coverage, US > EU/China-imported > Japan.

BH6KWC

The differences lie only in the frequency bands and minor variations, with different frequency bands affecting communication. For example, the 160-meter and 80-meter bands used in the Japanese version are different from those used in Europe and China, resulting in discontinuous transmissions.

BH6KWC This can be used directly through the radio's MENU.>SET>Function>The user band edge can be directly modified, and there are also modification methods described in the manual.

I'll take some small items apart myself.
Everyone is experiencing this.

The European version of the power cord has an additional filter. I haven't seen any specific effects, but I have one that is the Japanese version.

Also, this machine is about to be discontinued soon. If you buy it now, you might not get the latest models, which are likely to be more expensive.

HeyCharlie

The Japanese version cannot operate on the wider frequency bands, and therefore doesn't support some frequencies that are used in China. The main difference is the frequency band; the European and US versions both use wider bands, while the Chinese version uses a narrower one. The prices also reflect this: the Japanese version is significantly cheaper, with the lowest models costing less than 7000.

Bi4KKF

HeyCharlie The Japanese version supports wider bandwidth, including a 5 MHz band. It has been tested and works as expected.

BG2EFX

HeyCharlie The Japanese version is available.

Midea uses $ to buy; Japanese version, bought from Oki.

Well, I've been really wanting to get a used 705 recently. After seeing so many, the first thing that comes to mind is the Japanese or American version of the 705.

BG7NOD

HeyCharlie The used price isn't much cheaper than a new one, so it's better to just buy a new one and have peace of mind.

HeyCharlie

BG7NOD Let's wait and see if it's possible to register for the Chengdu exam after the year. So, there's no rush. Currently, a new version of the US-made 705 is about $1500 more expensive than used ones. Everyone is waiting for someone to buy one.

ICOM's Japanese versionShortwave radio stationIt seems like you can handle all communication, including but not limited to models 705, 7300, and 7610, simply by disconnecting a few pipes.
Additionally, according to unconfirmed reports, the Japanese version may have slightly stricter ingredient requirements, so if you can get the Japanese version, it's best to choose that one.
