F3

Northcoast D102US installed in a F3A. I did not use the factory lighting circuit, I wired a LED and resistor directly to the decoder.

Soundtraxx DSD installed in a F3B. I used a hacksaw to cut the frame where the cab would be in an A unit. I cut it to just above the worm housing, removing less than a half ounce of metal. I then made a ABS box around a 1.1 x 1.6 speaker using hot glue. I removed the factory PCB and put the decoder in that space. The rest of the ABBA set have NCE D102US decoders. The ST unit runs slower at a given throttle setting than the NCE units so I guess the PWM differs significantly between the two, I enable one of the a speed curves in the ST unit, and adjusted the trim CV.
