Ok so running day 5. Turned on power; returned A unit is ok, super bass B unit ok, trailing A unit is starting up in conventional now.
Remove shell, found magnet glued to top of shell with double sided sticky tape has fallen down and noted that there are two wires to the antenna. One wire was loose, resoldered, reprogramed, shut power off and on, ID remembered.
When did the Antennas go to two wires and sticky taped to the shell? This is what gets Lionel into trouble... non-standardization.
Well, will continue running and will report out what I find.
