(Near-Term Data Radio) wide-band networking transceiver. HCDR has a
225-450 MHz operating frequency range. It has wideband (5 MHz) and
narrow band (500 kHz) modem configurations, with a user rate of 288
kbit/s on a 375 kbit/s channel and 576 kbit/s on a 750 kbit/s channel.
Some 3,600 HCDRs are being supplied. HCDR provides a self managing
mobile Internet Backbone using standard RFC interfaces and routing
protocols.</p>

Pecora and Carroll discovered that one can feed part of the state of one Lorenz system into a second Lorenz system, and the second Lorenz system will exponentially converge to the same state as the first system, even if the synchronizing signal is corrupted with noise(!). It's like some kind of psueodrandom, chaotic "phase locked loop"—very exciting
