I'm running Trimble FMX on RTX in 2 tractors. For some reason this spring it's been taking 20-45 minutes to converge. This has never been an issue in prior years of running RTX-the only thing that's changed is I had my firmware updated to version 10.13. So far I'm having a tough time finding any answers so I'm wondering if this is a problem with the RTX signal or it's somewhere on my end.
