I have a simple set-up, which is a temporary layout using Fastrak, a ZW-C with two power bricks and a Legacy CAB2 and base station updated to version 1.60. I only set this up a few times a year and until recently it has run without trouble. Everything's at floor level with no metal bridges or tunnels but obviously there is furniture nearby.
Now, and while testing out a new Legacy crane and boom car, it's become obvious that there's a signal problem. Main issue is that I cannot get the crane and boom car to answer the CAB2 without putting my hand over them. Tried setting up the track in another part of the house but same result with these cars. Also a Legacy engine I put on the track shows a tell-tale flickering headlight every 3-4 feet along the track unless I put my hand over it. We haven't changed anything in our electrical system but this is a condo and there has been structural work on either side of us recently.
I've read about people with this problem connecting wires to the earth ground on water pipes or other metal fittings and looping them near problem areas. I'd consider doing that if it works but frankly I'm thinking that I might have to run a wire under/next to the Fastrak everywhere.
In case it matters we are also surrounded by WiFi networks and numerous connected devices including our own, but I am not sure that this affects the CAB2 and base station operation so as to produce the results I have described.
Any suggestions gratefully welcomed!
