Thanks for the input.. As i understand it DCC , modulates the drive power to the rails with the serial data , this has to be rectified then smoothed , then switched by the DCC decoder, at all stages power is lost . idealy you have to start at a higher voltage. The DCC message strings seem over complex and was probably designed for other systems ? several locos on a singgle track.. OK I have already taken into account, points and track devices also ... Alec I have not tried to changed freqency, I have a fixed 100 hz time base .. will give it a go thanks.. It is the starting from a standstill that is a bit random ..could be I need a block of power for the first pulse ...
EDIT I just checked my time base its 3 khz probably too high..don't know why it was 100 hz..
EDIT 2 .. Now running time base at 1 . 95khz and loco low speed much improved...
