[upl-image-preview url=https://storage.hamcq.cn/2024-10-12/1728736521-793911-img-0895.jpg] 上面的线插天分发现识别不了，看起来比下图 nanoVNA-H 天分孔深，这正常吗？（就差最后焊馈线就做出第一个自己的天线了，没想到天分识别不了馈线，不想错过 iss 的活动啊 QAQ）

但是 k5 的子头针好像挺长的，插上去或许能用？请问有检测的方法吗？

看起来不正常，应该和绝缘体平齐

@"BG2GNF"#p36609 可以试试，不要发射就行，反正光收iss

@"BI4PMQ"#p36610 谢谢您的回答，再买一根邮寄来不及了，好不甘心啊...😭只能焊上去试试了

不正常的，SMA 头经常坏掉，可以多买点备用。买的时候注意仔细核对规格。

我之前买了个小八木天线，附带的馈线多了个转接头，那个转接头里头的中心线要滑动，导致这个拧在K5机器上接触不好，只能反过来拧在天线一侧。

Is the wire inside the mother-board feed line deep and normal?

BG2GNF

The coaxial cable I connected to the antenna port is not being recognized, and it appears to be deeper than the nanoVNA-H's antenna port. Is this normal? (I was just about to complete my first homemade antenna by connecting the last feed line, but the antenna port isn't recognizing it. I don't want to miss out on ISS's event! QAQ)

BG2EWI

BG2GNF 不正常，馈线内芯的导体应该与同轴绝缘体端面齐平，稍稍低一点也可以用，但是太深的话内芯的插针就接触不到了。建议检查制作的步骤，是否存在过度拉伸馈线导致内芯缩回的情况

However, the sub-pin of the K5 seems quite long; perhaps it could be used? Are there any methods to test its suitability?

BI4PMQ

BG2GNF You can try it; just don't transmit anything. Since you're only receiving from ISS, it shouldn't matter.

BI4PMQ

It appears to be out of alignment and should be flush with the insulator.

BG2GNF

BI4PMQ Thank you for your response. I don't have time to order another one right now, it's so frustrating...😭The only option left is to try soldering it on.

BG5VQE

The SMA connectors are prone to failure, so it's a good idea to buy extra ones as spares. Be sure to carefully check the specifications when purchasing.

I previously purchased a small Yagi antenna, which came with an extra connector. The center conductor inside that connector needed to be adjustable, but this made it difficult to connect the antenna to my K5 radio; I could only attach it in reverse.
