David,
we thought about the caps and did give 30-60 sec. Actually i first tried it in conventional with a Z 4000 at our train show yesterday. when I got home I tried it with the DCSRC, it worked fine, and then disconnected that and went with a Z1000, to no avail.
Will be running it in DSC here at home, so conventional is really not needed, but would be nice it i wanted to take to another layout.
Thanks to all the responses
