最近想给老设备出一出买一台icom7300或者ft710 一直纠结 7300二手5000-6000 ft710大概看一下5800-6500 有二手也有全新日版的大概价格都小黄鱼上看的最欢710的外接屏幕但是都说7300皮实抗造 710爱坏操作起来不如7300友好 7300mk2出了感觉7300还会跌目前已知最低价在5000左右日常只ssb用 ft8有其他机器求助各位老师给点建议！

电磁环境好，底噪低7300，电磁环境差，有强干扰710，需要远程控制7300，不需要远程控制，偶尔野架710，长时间挂机24小时开机7300，使用时间一般710

710爱坏的就他那个塑料功放管，注意点使用没那么爱坏，天线别高驻波，ft8 cw别满功率，注意电台散热，少用端馈等等

综合接收性能710是比7300强不少

@"IL-1"#p96635 收到主要是买二手综合考虑价格

买3台，那个用顺手留哪个呢？

建议两台都买来对比玩玩看，都是不错的选择

@"IL-1"#p96636 端馈有什么影响？

@"BG7MGW"#p96774 端馈是不平衡天线，共模电流高，会干扰电台，严重的甚至会导致电台受损，有人的电台用端馈玩cw，共模电流导致cw的接线也产生了电流，把cpu击穿了，都没法修

@"IL-1"#p96777 端馈接个短地网或者加个扼流圈，接线加磁环呢？

icom7300 or Yaesu FT-710?

I'm considering buying a used IC-7300 or FT-710 to upgrade my old equipment. I've been debating between the two, with the IC-7300 available for around ¥5000-¥6000 and the FT-710 priced at approximately ¥5800-¥6500. Both new and used versions are available, and the prices seem to align with what I've seen on online marketplaces. While I prefer the FT-710's external screen, many users recommend the IC-7300 for its robustness and ease of use. They say the FT-710 is prone to issues, while the IC-7300mk2 is a more reliable option. Currently, the lowest price I've seen for the IC-7300 is around ¥5000. I primarily use an SSB radio, but I also have an FT-8 on another machine. I would appreciate any advice from experienced ham radio operators!

IL-1

Good electromagnetic environment, low noise level of 7300, poor electromagnetic environment, strong interference of 710, requires remote control (7300), does not require remote control, occasional use of 710, long-term standby, 24 hours on/off with 7300, average usage is 710.

IL-1 The main reason I bought it was to consider the price of used items comprehensively.

710 – Pay attention to the plastic amplifier tube, don't overuse it. Also, avoid high-frequency operation and full power transmission on FT8 CW mode. Be mindful of cooling and minimize the use of end-fed antennas.

IL-1 What are the effects of end-to-end transmission?

IL-1

The overall receiving performance of the 710 is significantly better than that of the 7300.

MK2 has not been approved.

I'm buying three of them. Which one should I keep?

BG7NOD

I recommend buying both and trying them out to compare; they are both good options.

IL-1

BG7MGW Using a feed-forward antenna results in an unbalanced antenna, with high common-mode current. This can interfere with radio stations, and in severe cases, even damage them. Someone used a feed-forward antenna with CW (continuous wave) to operate their radio, but the high common-mode current also caused current flow in the wiring, which fried the CPU, making it impossible to repair.

BG7MGW

IL-1 Should I connect the output to a short ground wire or add a magnetic clamp, and how should the wiring be done?

BG7NOD

By the way, the performance of the 7300 MK2 has declined, and I believe its price should still be relatively stable compared to the first generation.
