Just curious:
Would it also work if the booster is powered by an external source and the LDCC
RCX draws its power from the track? Or does the booster have to sense the
presence of the DCC controller before it supplies power?

| Yes (to the second question :), the booster code will cut power if the polarity of the track power hasn't changed for 10 milliseconds (or if no power is detected). Basicly, the command station is always sending out packets by flipping the polarity (...) (21 years ago, 9-Jul-03, to lugnet.trains)
