I have an unused fixed channel on my TIU. Will jumpering the output of the unused channel to one of the other used channel's outputs increase the signal strength for that used channel? There are places on my layout I have not been able to successfully get 9/10 signal strength even when trying bulbs/filters. This is an older TIU, not a Rev L. Some of this is probably caused by the number of active engines and passenger cars on the layout at one time; I can get much better signal strength when only a couple of trains are on the track at one time.
