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?

Please refer to this post, which describes continuous transmission from 1.8 MHz to 30 MHz. However, the PTT (push-to-talk) function at 27 MHz does not transmit when pressed, and a local ham has personally verified that it is feasible.

BG5BQB The link has been reset and I can't see the content. Could you please send it again? Thank you.

BG7NOD Additionally, for non-professional use, the power output cannot be guaranteed, and this applies to all machines.

BH3XZT

BG7NOD The UV band of the 705 device can only currently receive; it cannot transmit.

BG7NOD

BH3XZT As for the UV band, it doesn't matter. But regarding the shortwave band, can we amplify and receive signals in that band?

BG5BQB

BG7NOD You need to climb a ladder to see it; once you've climbed the ladder, you can see it. The Reddit post.

BG7NOD

BG5BQB Wow, there aren't even any reposts within China?

Saurlax

So, does it basically just require software adjustments, or do I need to disassemble the machine and modify the circuitry?😨I recently saw some Japanese goods on Taobao selling for around ¥6,000. The prices seem very attractive, even cheaper than secondhand items (though I'm not sure if there are any even lower).

BG7XLY

Saurlax Yes, I just got my B license last month and would also like to go on a trip with the Japanese version of the 7300.

BG2EWI

Saurlax In the Japanese version, you need to remove a few diodes and then disable the frequency lock in the settings menu. This will allow you to use the full bandwidth (0-70 MHz) in all modes.

Essentially, all of this information can be found in this video:https://www删.yout删ube.com/watch?v=GLYAejGenuk
