To all of you "techs" out there. I have a "new old stock" K-Line, NYC, J-1 that will not sound the Whistle continuiously (holding the Button down)while using TMCC and Cab-1. Holding the button down produces a Whistle that goes and stops. I tried it with (2) different TMCC Bases and Cab-1s. It works fine with Lagacy and Cab-2.
It has Lionel Boards in it, so I changed the following components; R1LC-08, Railsounds and Power Board. I even changed the Motor Board, since Serial Data Line goes to it. I also created another antenna wire to see if it helped at all.
So far, there is nothing I have done that makes this problem go away.
Any ideas?
