最近 K1 的开源固件出来了，真的很感谢 Armel 把底层开发得这么好，我这才有机会把以前给 K5 写的功能移植过来。这次加的是个 MSG CW 尾音。很多人喜欢摩托罗拉那种 MDC 信令，听着确实响亮，但在咱们 HAM 的实际通联里没啥大用。我搞的这个 CW 尾音就实在一点：怎么玩：菜单里 Roger 选 MSG CW。然后用 Chirp 在开机欢迎词的第二行（Line 2）写上你的呼号就行，要是第二行没写，它就默认读第一行。有什么用： 1. 听音识人：像菜市场一样大家扎堆聊天的时候，光听声音容易搞混，加个独特的 CW 尾音，能秒懂是谁。 2. 整理 Net 记录：平时录音或者整理通联日志的时候，这个就是你的“数字指纹”。虽然设了 100 WPM 听着很快，但在频谱瀑布图上一眼就能认出来，方便回溯。 3. 合规：规矩要求咱们要定期自报呼号，这个功能相当于每次发射完都自动帮你“自曝家门”，省心又稳妥。默认速度调得很快，不占频道时间，听感也比 MDC 斯文不少。大家感兴趣的可以刷进固件试试，有问题随时交流。源码 [GitHub](https://github.com/bg7nzl/uv-k1-k5v3-firmware-custom) 下载地址 [Release](https://github.com/bg7nzl/uv-k1-k5v3-firmware-custom/releases/tag/bg7nzl-v0.1)

今天在GITHUB上看到了，没想到是国内大佬做的。感谢！

所以这是CW 摩斯电码玩法的尾音吧。

大佬有没有给旧版K5/K6用的固件

@"BG9JXB"#p90543 你是多大容量的呀，k5我是根据最早出来的固件的来写的，中文频谱什么的都不支持。我晚上回家可以试着移植到losehu上看看

@"bg7nzl"#p90559 扩容512k的，移植成功我的K6就又可以拿出来不躺在那吃灰了😂

@"BG8LGP"#p90562 芯片不一样，一般k5/6是老版v1芯片，k5/6 v3才和k1是一样的芯片，固件不通用。k5/6 v2出货太少了被战略性放弃了

希望能有外接电键的真.cw功能，类似cec固件那样

大佬您有解码固件的软件之类的吗，我的CEC0.3V固件想解锁全频段，但是因为刷了多系统按照设置会进刷机模式，所以想通过修改固件来解锁全频段

@"BG5JKZ"#p90608 可以试一下在开机的一瞬间按下进入设置的按键，这样跳过上电多系统切换的判断就可以进入固件自己的隐藏设置部分了

I've added a fun CW tail-end function to the K1! It automatically transmits the call sign.

I saw it on GitHub today and was surprised to find that it was created by a prominent figure in China. Thank you!

BD1DHZ

So, this must be the concluding part of playing Morse code using CW (Continuous Wave).

BG9JXB

Does anyone have firmware for older K5/K6 models?

bg7nzl

BG9JXB What's the capacity like? The K5 is based on the earliest firmware, so it doesn't support Chinese spectrum or anything else. I can try to transplant it onto my Losehu at home in the evening and see if it works.

BG9JXB

bg7nzl I successfully upgraded my K6 from 512KB to a larger capacity, and now I can use it again without having to leave it lying around.😂

bg7nzl

BG9JXB Okay, I finally managed to get it working after a long night. "Losehu" added so many firmware features that he had to optimize a lot of things before adding the new features while still maintaining functionality. The usage is the same: just set the second line of the startup information and then choose the "cw" accent in the final option.

P.S.: It seems I can't upload the ZIP file here. I've uploaded it to k5.vicicode.com. Please search for a firmware called "CW Tail Code". Once it's approved, you should be able to use it directly on the webpage.

BG8LGP

What are the differences between K1 and K5/6?

bg7nzl

BG8LGP The chips are different; K5/6 are older versions (V1), while K5/6 V3 uses the same chip as K1. The firmware is not compatible. Due to low sales, K5/6 V2 was discontinued.

BD8DIN

I hope to have a real .cw function with external switches, similar to the CEC firmware.

bg7nzl

BD8DIN Since you've asked sincerely, I'll do as you wish! Now there's an additional CW mode, and listening to frequencies around 650 Hz should be quite enjoyable. Currently, it uses a single-button PTT (Push-To-Talk), which works with the handheld microphone's PTT button as well. This is very suitable for converting to an external, direct key.
GitHub

BG5JKZ

"Sir, do you have any software that can decode firmware? I'm using a CEC0.3V firmware and want to unlock the full frequency range, but when I try to set it up after flashing multiple systems, it enters boot mode. I was hoping to unlock the full frequency range by modifying the firmware."

bg7nzl

BG5JKZ You can try pressing the "enter settings" button immediately after powering on. This will bypass the system switching judgment and allow you to directly access the hidden settings section of the firmware itself.

BG5JKZ

bg7nzl I just tried it, but it didn't work.

bg7nzl

BG5JKZ Is that all?👻

BG9JXB

bg7nzl Thank you very much. Currently, it may not have been approved yet, and I can't find it anymore.

BG2ELG

Correction: The Morse code sound used for FM modulation transmission is CW, not code-tone (I'm just pointing out the difference).

bg7nzl

BG2ELG Okay, I've added a TRUE CW version specifically for you to use via email!

bg7nzl

bg7nzl For example, if you use AIOC (or similar software), you can even have your computer send emails automatically!

BD8DIN

bg7nzl 感谢感谢，这就去贡献star

Bi4KKF

The speed is too fast, making it difficult to understand. The delay after receiving a message is longer than the actual spoken word, which hinders communication.

bg7nzl

Bi4KKF 对的，所以这个的设计目标并不是让人清晰可读，而是可以让在录音或频谱上以后可以辨别是谁在说话。所以设置了100wpm，这样呼号会在不到一秒钟内放完，对于顶级人类，也可以通过音色来判断。结合菜市场多少人守规矩按照要求定时识别自己，这个就可以满足合规性（给无委看），当然，更多是一个个性化玩具。👻
