I'm not sure if this may be of any help or not, but, I have a splitter
for my walkman and I notice that it takes more power to run both
headphones (obviously). I'm assuming that this will be the same with the
calcs but not as severe. I don't know what the resistances on the
splitters are either, but, I first thought of remedeing the prob by
suggesting a powered hub to amplify the signal, then I realized that
each calc in the chain could be used as an amplifier. One calc transmits
a signal to the next calc in the chain, it checks if its for that calc,
and resends it to the next one. Maybe this is a possible suggestion for
getting a network together, then again maybe not (too slow?)
