  • Electronic morse-key with squeeze facility
  • Speed adjustable from the front-knob between approx. 40 ...400 lpm
  • Weight adjustable from the front-knob between approx. 1:3 ...1:5
  • Tune button with optimized tuning facilities for PAs
  • switchable pilot tone with low current consumption piezo
  • buzzer (approx. 800 Hz)
  • special "low current" design for minimized power consumption. The keyer is switched into "sleep-mode" automatically after a few minutes without action, resulting in a current of a few ľA only. Normal current is approx. 1.5 mA. Power supply uses three batteries guaranteeing more than 1000 hours of pure morse fun !
  • DIP-switches at the rear of the keyer include the following functions:
    1. Dot memory on/off
    2. Dash memory on/off
    3. Switch paddles (for left handed OPs etc.)
    4. Sidetone on/off
    5. Reset (for service)
    6. Battery disconnect
  • External keyer connection via 3.5mm stereo plug
  • Keying signal at rear cinch socket is isolated by optocoupler
  • Included non-servicable paddles with very high precision using special contact materials
  • Paddle-distance and pressure-force can be adjusted after opening the enclosure
Recommendation : Use high quality batteries to avoid damages by leakage.
If you don't need the keyer for a longer time, please remove batteries !
