[Elecraft] Remote encoder?

[Eric Rosenberg]

One of the nicest features of the Orion (and previous Ten Tec rigs) is 
the availability of a remote encoder - a tuning knob off the rig.  Over 
the years, they've ranged from the encoder (tuning knob) by itself, or, 
in its present incarnation, a tuning knob and keypad.

Is there an equivalent for the K3 (presumably a third-party developed item)?
