The P6 is a single lever paddle that does not allow the dot and the dash contacts to be closed at the same time. Often times this can eliminate a lot of sending errors for people who do not use true iambic operation (like me!). This paddle weighs 4 lb and is made of solid brass. Like all K8RA keys, it uses silver contacts and precision miniature ball bearings. The initial adjustments (click below) are a little harder than the iambic keys but once set it should never have to be changed. The key is coated with lacquer for lasting beauty. In operation the P6 is very smooth and solid.
