手头只有K6,所以打算再uv频段ft8。硬件都整的差不多了（其实就是买了个aioc的板子，自己焊看跟延长线，在延长线上焊了俩耳机插头）。正式测试通联前跟诸位大佬们请教几个问题： 1. 1. 是否存在uv段的不常见的频率段，前期操作不熟练，先在无人频段上进行测试练习； 2. 是否存在ft8常用的uv频段，用于正常通联，要是没有就只能跟大佬们约定时间跟频率了，总不能上中继吧； 3. 针对固件，由于没有刷多系统，也是怕自己手残刷砖。看到网上的教程都是用CEC的固件，但是平时losehu的固件用着方便，我看着losehu131的固件好像暂时没有支持ft8； 73 后面有啥情况再来汇报。

不建议从UV开始接触FT8，UV DX是以挑战自我为乐趣的进阶玩法，很难有通联实践的机会，6m这个季节一天都蹲不到几个台，更别说2m和70cm了，对自己和电台都是一种摧残。

@"Liridice"#p41581 确实，传播季已经过去了

@"BG5BQB"#p41582 @"Liridice"#p41581 没办法，苦于设备及操作证级别限制，只能UV段了，就当熟悉操作为后续积累经验吧。

还不如买个八木打卫星呢

有约定频段，但是没人。有传播的时候都没几个人，没传播就没人了。只能约通联了既然受限于操作证级别，还想玩FT8,可以试试6米波段。但是传播很魔幻，现在季节也过去了。偶尔倒是还能看到人。

@"BI4MIG"#p41585 先把lotw注册了，然后在本地的ham群里找机会跟大佬们出去野架，只要你有诚意，摸摸别人的电台，实习发射一下不是问题。

@"Liridice"#p41581 所以要先尝试有稳定靠谱传播路径的VHF/UHF活动，比如EME🤣🤣🤣

楼上关于6米的说法并不准确，此时此刻6米FT8依旧有VK、DU、KH0、JA等字头出现

@"BD4RHV"#p41650 感谢大佬指正

Ready to start practicing using FT8.

BI4MIG

I only have a K6 radio, so I plan to try UV frequency FT8. The hardware is mostly complete (basically, I bought an AIOC board and soldered it myself, along with extension cables, and added two headphone jacks to the extension cables). Before officially testing for communication, I would like to ask some questions from the senior members of the community:

1. Are there any uncommon frequency bands within the UV spectrum? If so, it's advisable to first practice and familiarize yourself with operating in the unlicensed band before attempting operation in the UV spectrum.
Are there any commonly used UV frequency bands for FT8 that allow for normal communication? If not, we would have to coordinate times and frequencies with experienced operators. It wouldn't be possible to rely on a repeater.
Regarding the firmware, I'm hesitant to flash it because I don't want to accidentally brick my device. The tutorials online all mention using CEC firmware, but I find that the losehu firmware is convenient to use. However, I see that the losehu131 firmware doesn't currently support FT8.

I will report back on the situation once it develops further.

I don't recommend starting with UV before trying FT8. UV DX is an advanced mode that focuses on challenging oneself, and it's difficult to find opportunities for consistent communication. With 6m, you can rarely contact even a few stations in a day, let alone 2m and 70cm. This would be very frustrating for both the operator and the station.

Liridice Indeed, the promotional period has already ended.

Unfortunately, I'm limited to the UV spectrum due to restrictions on equipment and operating certifications, so I can only work with that. I'll just treat this as an opportunity to gain experience for future use.

Liridice Therefore, it's best to start with VHF/UHF activities that have a reliable and stable communication path, such as EME.🤣🤣🤣

BI4MIG First, register with LOTW. Then, look for opportunities to go out and practice with experienced hams in your local ham radio group. As long as you show genuine interest and are willing to listen to other people's radios and try a short-range transmission, it shouldn't be a problem.

It's better to buy a Yagi antenna and use it for satellite communication.

BI4PMQ

There's a designated frequency band, but no one uses it. Even when there's activity on the channel, only a few people are using it; and when there's no activity, it's completely silent.
I can only communicate via Tonglian.
Since I'm limited by my operating license level, and I still want to try FT8, I could try the 6-meter band. However, propagation on that band is quite unpredictable, and the season has also passed. Occasionally, I can still see other people using it.

BD4RHV

The statement about 6 meters being exclusively used for FT8 is inaccurate. Currently, the 6-meter band still has activity with stations starting with VK, DU, KH0, JA, etc.

BI4PMQ

BD4RHV Thank you for pointing out the errors.

BH5UNT

In fact, you could consider cheaper options like the ADX-S or ADT from BD6CR.Shortwave digital transmission and reception deviceThe kit, as a self-made aircraft license.

I can enjoy using FT8/FT4/JS8/WSPR with 300 yuan.
