The Adventure dual-lever key, like its single-lever sibling, the Adventure Mono, was created to give you the finest possible keying experience with today’s portable radios.
The base of the key is made from stainless steel. The arms and the finger pieces are a lightweight aircraft aluminum alloy. Several other components are gold plated, and the contacts are solid gold. The return force is created by adjustable magnets.
The contact spacing can be adjusted with the oval backstop ...
The key uses magnets to create the return force which can be adjusted by the golden thumb screw on the bottom. You also see the two precision bearings for the arms.
The key is attached to your radio with a mounting bracket, which lets you swivel the key at an arbitrary angle for maximum comfort in right-handed or left-handed operation. This is the mounting bracket for the Elecraft KX3 and KX2, but we also offer mounting brackets for the Elecraft KX1 and the Yaesu FT817.
The magnetic desktop base lets you use the key detached from the radio on a desktop or on any metallic surface that the magnets in the bottom of the base can hold on to. The combined weight of the key and the base is about half a pound - so, if you have a heavy hand and no metallic surface for the magnets, you can use the mounting holes in the base to secure it in place.
