本人自从2025年3月份取得业余无线电A级操作证书后，4月份购买了两部泉盛UV-K6对讲机并获得电台执照，5月份完成了首次随机语音通联。因为我平时从不发微信语音，所以对使用模拟对讲机进行中文文本通信很感兴趣，仔细比较研究后找到了一款开源的安卓软件Rattlegram（https://github.com/aicodix/rattlegram），经过直频与中继测试抗干扰性强，每条信息仅占用信道2秒，因此本人制作了Rattlegram汉化版软件，希望能在U/VHF波段非语音通联方面为大家做点贡献。使用：1. 模拟制式对讲机（不限型号）频率设置与语音通联相同，参数设置声控发射（VOX）为1，静噪为1，MIC灵敏度为1，音量调至最大。 [upl-image-preview uuid=cc8c0c7e-9153-4567-80ac-f3ef360bfa87 url=https://storage.hamcq.cn/2025-06-20/1750408193-212256-img-20250620-105515.jpg alt={TEXT?}] [upl-image-preview uuid=26d46e0f-9e30-4dc2-bb32-932a5fa9f05f url=https://storage.hamcq.cn/2025-06-20/1750408191-200134-img-20250620-105453.jpg alt={TEXT?}] [upl-image-preview uuid=7c7bdd22-62cd-412d-b992-881ff7102a6c url=https://storage.hamcq.cn/2025-06-20/1750408189-48752-img-20250620-105351.jpg alt={TEXT?}] [upl-image-preview uuid=ddb15c6f-4c86-47c6-a54a-9b720ee368e4 url=https://storage.hamcq.cn/2025-06-20/1750408186-844852-img-20250620-105338.jpg alt={TEXT?}] 2. 对讲机（K1接口）与手机之间建议使用本视A-1体验线连接，如果不具备连接条件可将对讲机与手机挨近放置使用。 [upl-image-preview uuid=73c7af6f-516d-4edf-896f-68b87189e20b url=https://storage.hamcq.cn/2025-06-20/1750408195-270208-img-20250620-105733.jpg alt={TEXT?}] 3. 安卓手机（建议Android7以上）安装Rattlegram汉化版，要求允许麦克风使用权限，参数设置默认即可，修改呼号（仅限大写英文，数字），音量调至最大。 [upl-image-preview uuid=8e41bced-3400-4a91-b824-28c6778f91d7 url=https://storage.hamcq.cn/2025-06-20/1750408209-238855-img-20250620-121945.jpg alt={TEXT?}] [upl-image-preview uuid=df365f97-b0af-491f-97f3-26bf7cc77adf url=https://storage.hamcq.cn/2025-06-20/1750408197-972780-img-20250620-111614.jpg alt={TEXT?}] 4. 使用时建议双方先互相发送PING检测通联效果，文本发送建议控制在85个英文或28个汉字以内（强力模式）。 [upl-image-preview uuid=db53bf5f-52d0-4e8a-bfa0-3556037f1b07 url=https://storage.hamcq.cn/2025-06-20/1750408201-601296-img-20250620-111919.jpg alt={TEXT?}] [upl-image-preview uuid=7eca92f4-64be-4aed-915f-82cfad165325 url=https://storage.hamcq.cn/2025-06-20/1750408205-307632-img-20250620-112012.jpg alt={TEXT?}] 本人创建了模拟对讲机文本通信群（857287107）以便联络沟通，需要软件请进群下载，如有疑问请加QQ（2875106324）交流。

使用的是什么编码？很想知道，像APRS那样的声音？

这个可以离网收发吗？🧐

全程要vox打开吗？那在旁边说话会触发vox本身的发射吗？

A powerful tool for simulating text communication over radio! Rattlegram

BI3BJU

   本人自从2025年3月份取得业余无线电A级操作证书后，4月份购买了两部泉盛UV-K6对讲机并获得电台执照，5月份完成了首次随机语音通联。

Because I rarely use voice messages on WeChat, I am very interested in using a simulated walkie-talkie to communicate in Chinese text. After careful research and comparison, I found an open-source Android software called Rattlegram (https://github.com/aicodix/rattlegram), after testing its interference resistance with direct frequency and repeater, each message only occupies the channel for 2 seconds. Therefore, I have created a Rattlegram localization software version, hoping to contribute to non-voice communication in the U/VHF band.

Usage: 1. Simulate standard radio frequency settings and voice communication with the same parameters, using voice-controlled transmission. (No specific model is required)（VOX）For channel 1, noise level set to 1, microphone sensitivity set to 1, and volume adjusted to maximum.

2. It is recommended to use the A-1 experience cable (with K1 interface) to connect the walkie-talkie and mobile phone. If a connection cannot be made, the walkie-talkie and mobile phone can be placed close together for use.

3. Install the Rattlegram Chinese version on your Android phone (recommended: Android 7 or later). You will need to grant microphone permissions. The default settings are sufficient; you can modify the call sign (only uppercase English letters and numbers) and adjust the volume to maximum.

4. When using, it is recommended that both parties first send PING tests to verify connectivity, and that text messages should be kept within 85 English characters or 28 Chinese characters (in strong mode).

What encoding method are you using? I'm really curious to know, especially if it's something like APRS audio.

Interesting gadget😍

BH7GXJ

Can it be used offline?🧐

BI3BJU

BH7GXJ The phone can be used without any network connection.

BI2UE

Does Vox need to be turned on throughout the entire process? If so, would speaking nearby trigger Vox's own transmission?

BG5ELQ

BI2UE He connected them with wire; the air connection will affect it.

BI3BJU

BI2UE For wired connections, VOX needs to be activated manually by the phone. Activating VOX wirelessly can cause background noise to trigger the transmission unintentionally. Therefore, when using wireless VOX, it is recommended to press and hold the PTT button with one hand while sending a message with the other hand.

BI2UE

BG5ELQ If I use a cable to connect my headset, will it still transmit audio? I haven't used a cable to connect my headset before.

Communication in Chinese?
Hey!
I was just thinking about an old friend...

The CRAC information download also has something similar.Data communication program CP16It was published in 2015, but there is very little related information available on the Chinese internet.

I took a look at it.GitHub repository for this projectThe first release was published in 2022.

BG7QVU Ten years ago was already 2015, and 2015 was already ten years ago.
