A problem that we all have encountered from time-to-time in the analog world is that we double with other stations. While on a statewide DMR net, I encountered the same problem. This prompted me to look at my TX Permit settings on the 878. It turned out that I had it set to ‘Always.’ A quick change to ‘Channel Free’ resolved the issue. Below is a list of the TX Allow settings:
| Setting | Description |
|---|---|
| Always | Always allow transmit |
| Channel Free | Allow transmit when the channel is free |
| Different Color Code | Allow transmit when receive matched signal but different color code |
| Same Color Code | Allow transmit when receive matched signal and same color code |

Different Color Code, or Color Cde Free (Moto) unless you are on simplex. Only use Always on simplex.
