Keyer / Paddle Model KR20

The KR-20 provides crisp easy-to-copy CW at all speeds without operator fatigue. The paddle assembly incorporates a linear magnetic paddle return. Return force is adjusted by two front panel knobs which move magnetic shorting bars. Each paddle can be set individually to optimum tension. Paddles can be canted for the most comfortable position. Contact spacing is adjusted thourhg hole in the top of the case.

• Keyed Time Base: Each character starts immediately when the paddle is actuated. A momentary closure of either paddle is all that is necessary to form a complete character.
• Weight Ratio: The traditional keyer has a dit-to-dah ratio of 1:3. A space has the same length as a dit. This dit-dah-space ration is fairly smooth at higher speeds, but becomes choppy at speeds below 25 wpm. Accordingly, we have incorporated a character-to-space ration extender to suit individual preference. The monitor, however, has the conventional 1:3 ratio.
