Is there a way to make my rover stop going into red fixed?

To prevent your Carlson BRx7 rover from going into red fixed mode (losing RTK fix and dropping to float or DGPS), ensure the following:

1. Maintain Clear Line of Sight: Avoid moving the rover into areas with signal obstructions like trees, buildings, or terrain that can block communication with the base.

2. Use Internal Radio Properly: Make sure the UHF radio antenna is connected properly and configured to match the licensed frequency and protocol (e.g., TrimTalk, PDL) used by your base station.

3. Check Radio Settings: Confirm that the internal radio settings on the rover match those of the base, and the correct protocol is selected.

4. Monitor Voice Prompts: The BRx7 gives voice indications for RTK status. Listen for changes to know when the fix is weakening.

5. Avoid Movement During Static Logging: If using static mode, the device stops logging if it detects movement. Keep the rover stationary while logging in static mode.

Proper setup and maintaining signal quality will help avoid losing RTK fix.
