收发频率没设置对吧，频率对了。起码设备有信号接收，但是没语音。色码时隙需要设置对了。发射联系人设置为46001，接收组也设置46001。应该没问题的。

刚才看了下频差。建议设置大一点。没试过，你这差1m的。下差5吧至少。

单工板的话，收发频率必须设置成一样的，对讲机也要用直频模式

@"BI1PND"#p58546 这个是双工板子，问题已经解决了，感谢回复！

@"bd3qdg"#p58533 问题解决了，是设置里面电台调制解调器类型没有选好，改了之后就可以了

请教一下，MMDVM的盒子应该是设置好了，网页里看没什么问题

但是手台一按PTT就会显示这个0的界面，但其实是没有发射信号的

如果按PTT持续4、5秒的话就会提示超时，但是在写频软件里没有限制手台的发射时间

这种情况应该怎么调整，是手台的问题还是盒子的问题☹

The frequencies haven't been set, right? The frequency is correct. At least the device is receiving a signal, but there's no voice. The color codes need to be set correctly.
The transmitting contact should be set to 46001, and the receiving group should also be set to 46001. This should work without any issues.

I just checked the frequency difference. I recommend setting it to a larger value. I haven't tried this before, but your setting of -1 MHz seems reasonable. I would suggest at least -5 MHz.

bd3qdg The problem has been resolved. It was because the radio modulation/demodulation type was not selected in the settings. After changing it, it now works correctly.

Regarding the walkie-talkies, the transmit and receive frequencies must be set to the same value, and the walkie-talkies should also be used in direct mode.

BI1PND This is a duplex board; the issue has been resolved, thank you for your response!
