The frequency of the RCX's IR does not change at all: " The RCX uses a 38kHz carrier, which is pretty typical for TV remotes. As for the sampling rate, the RCX runs at 2400 bps, which makes each bit approx 417us " (URL) think the only way you could (...) (22 years ago, 28-Sep-02, to lugnet.robotics.rcx.legos)

duh... guess i was kinda wrong here.. IR is in reality a frequency defined from A to B. any messages sent within this spectre is said to be IR messages. so in theory sending an IR message closer to A than B from one RCX. and at the same time sending (...)
