BI9BOT Could you please confirm that the MMDVM box has been set up correctly? I checked the website and didn't see any obvious issues. However, when I press PTT on the handheld radio, it displays a "0" interface, but in reality, no signal is being transmitted. If you hold PTT down for 4 or 5 seconds, it will display a timeout message, but the frequency software does not limit the transmission time of the radio. What adjustments should be made in this situation? Is it a problem with the handheld device or the box? ☹
bd3qdg 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.
bd3qdg 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.
BI9BOT 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.
BI1PND 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.
