This clever variation on THE Throttle was designed by Andrew Steenbuck. By adding a 4PDT relay to the
throttle base circuits, a selector toggle switch to the handheld and substituting a standard Ethernet network
cable and connectors in place of the telephone coil cord, you can leverage the memory feature of this throttle
to the fullest by "time-sharing" a handheld unit between two completely separate throttle base units.
