I was going to add this on to the Quill question but inadvently hit send ! ? ? When I open a test throttle in Sprog/Decoder pro it defaults to 128 speed steps. I have to go to preferences and change the bullit to 28 steps to get the full use of the slider. In command mode no problem. This happens everytime I open a test throttle in program mode. I hesistate to ask but i can't seem to find the solution on my own. Thanks, Rick.
