Randon behaviors have recently started to occur that prevent accurate communications from the Cab2 controller to the destination locomotive. The most frequent is a lack of speed control, but there can also be a condition when no commands from the handheld controller reaches the locomotive.
As seen in the photo, I have three independent Legacy 990 systems that control three independent districts on my layout. All three bases flicker when a command is dispatched from the handheld. Sometimes the command is accurately deployed, partially deployed, or nothing at all. One of the really confusing behaviors is the destination loco receives a signal, begins to crawl, but will not follow increasing speed commands, nor will it stop under any command. Power to the track has to be cut off.
I have cross-checked all combinations of locomotives, bases, handhelds. I have verified that all locomotives are functional. The train brake is set at "-", speed steps are set at medium 4 on the handhelds.
I have seen references to radio wave interference issues here on the forum. Given the random "on - off" behaviors I question if this might be the problem. So, the questions would be where the interference come from, and how to solve the issue.
