The CK-200 Electronic CW Keyer is a microprocessor-controlled keyer that provides iambic key operation and dot-and-dash memory to make sending perfect code easier. It has tunable code speed, code weight, and sidetone frequency. It supports both direct and grid-block keying outputs as well as relay contact output. You also get to choose between type A and type B iambic keying.
The CK-200 works with all tube and solid-state rigs and is powered by either a 9 Volt battery or an optional AC adapter.
