When I transmit using the OS2 I get a message at the bottom of the screen. "Color Code mismatch from receive modem" I have the color code set to 1 in the OS2 and the code plug. Sometimes I can transmit and the receiving party can hear me then when the message comes up it stops. This started happening right after recent updates. Any help would be appreciated.

This may be because of frequency misalignment between the OS2 and your radio. Try running DMR AutoCal or manually set an RX offset on the Modem page in +-100Hz steps and test your voice using the built-in local echo service by calling DMR ID 9999.

Thank you Norbert, that was the problem. Working fine now.
