因为家中没有阳台，且高层无架台条件年前对705心动不已，加上新规，10W的705更香了毕业第一次拿了年终，激动不已再三反复，终于下单了！但是下错了链接。。。目前设备仅仅开箱看了一眼保修条，是个ICOM730。就吓得丢回去了，机器泡棉都没开，没看真容设备在深圳，支持现场验货，求个有条件使用她的老哥收走 6950￥非偏远包邮

这个错误十分低级，这个水平实在是不敢多讲是我入坑无限垫以来最大，也是最惨的一次垫😭 要是本贴可以匿名就好了。。。

先留着吧，将来会用上的

@"BG4IJK"#p11236 那我得考到C证了，广东下半年考B，然后买个便宜的短波机设台，18个月后考C，然后申请大证简单算算得2.5年后才能用上。。。

第一眼看成了拼多多😄😄

自己玩呗。 A证,,,那就50M部分上执照就好，想玩50就50 或者(x)

IC-730？？这不是老爷机了吗？？这机子这价格？？我只能不评价了...

Brand new Japanese ICOM-7300 radio – looking for a good home!

BH8AVW

I've used the 450D, IC7000, FT891, and 756pro3, as well as the previous year's Yaesu 7300, but I still prefer the 7300 for portable operation.

Large screen, clear display, portable operation, high power.
The electromagnetic environment this year: To put it bluntly, using a QRP radio without a powerful antenna system is essentially creating trouble for others. A 100W transmitter can be heard and even used to transmit, while a 10W or 15W transmitter can only be heard but not used effectively. Furthermore, the faint voice will cause considerable distress to the recipient.

Of course, QRP CW is a different matter entirely! I don't want to use QRP SSB because I really can't stand having to repeatedly ask the other person for your callsign...

BH8AVW

BH8AVW By the way, I also have an 817, and it's constantly getting scrambled! It's really annoying when people keep asking me for my call sign multiple times. I think they probably lose interest in communicating with me after a while!

The infinite pad cannot be used with both a radio and an antenna, and it also requires a car to transport it. Otherwise, the radio and antenna will not be able to be carried when setting up in the field.😈

Keep the machine, and place another order for an IC705. Then, register the 705 and use it at home to transmit at 7300 watts. When reporting the equipment externally, report both the 705 and the 10 watts.

BH2VYJ ? I saw you!

BI4MIG

BH2VYJ That's too harsh.👍

BH2RSJ

Just keep it. I believe the 7300 will be much more useful. In terms of power,

Buying it for 7300 won't be a loss; this type of radio has very high resale value. It's better to keep it, even if you only use it quietly for 100,000 yuan.

最新进展，深圳有个同志正好有台22年的705，配件齐全，没野架，半吃灰
准备线下换掉

我需求705是觉得就算到了C，也需要一台便携设备，过于合适且合规

如果折腾了好的天馈系统，也还真喊不到，我就再给ICOM充值一波

Next question: Does anyone have experience using turtles?
The 705 power distribution system may require a😎

BA7OFW

BD7PPD-xiaohei-lv It's also preferable to have an XPA125 with a built-in tuner, especially at 100W.

BG6HXC

BD7PPD-xiaohei-lv Consult with MIIT (Ministry of Industry and Information Technology). Your 705 amplifier is non-compliant. Instead of both being non-compliant, it's better to write a guarantee statement for the 7300, testing it at 15W.

BG6HXC

BA7OFW This, combined with needing to replace the 7300, is actually worse than just keeping one radio. At least with one radio, I wouldn't have to connect two devices and use additional cables.

The question is whether the gain is high enough.
The antenna is good.

The amplifier clearly belongs to the terrestrial broadcast system... what's its relationship to a radio station? - Zhou Shuren

That being said, we've already switched to the 705, and so far haven't received any calls [doghead.jpg]

BD7PPD-xiaohei-lv Getting the antenna right is crucial. My G90N, using 10 watts via USB at 20 meters, achieved a maximum range of reaching Shenzhen, Guangdong, and Altay, Xinjiang. Once, I even managed to contact a match in Argentina, but it wasn't officially confirmed.
QRP requires a lot of patience and perseverance.
Additionally, FT8 is also worth trying.

BG7NOD

BG9CHE Forget about the G90N; it's really only suitable for outdoor use. With a lot of background noise in urban environments, you basically won't get any good results.

BG9CHE

BG7NOD However, I set up a MA-12 on my balcony in the city center (G90N+), using 10W power to make contact with stations in Argentina and California, USA, via FT8.
SSB can be heard in cities, but transmitting on a low power level is unlikely to work.

BG7NOD

BG9CHE Normally, I get a lot of S9 noise here, so… But yesterday, I discovered that someone had cut the antenna, and there's no point in continuing.

I saw a new 7300 on Xianyu for only 6000, and it includes shipping!
