Combination Voice Keyer
and Full Featured CW Memory Keyer


VK64 Voice CW Keyer - Click to Enlarge The VK-64 is a voice keyer and CW memory keyer in the same package!

You can operate the VK64 manually with the front panel controls or under program control through your PC or laptop's printer port.

The voice keyer section has four 15 second messages.

Recording is simple. Press the record button followed by a message number button and start talking. Press the stop button when you are finished. Messages are stored in non-volatile memory, remaining stored until recorded over with a new message.

The CW portion is an iambic memory keyer with four programable messages, each one capable of storing over 300 Morse characters. A front panel knob adjusts speed from 8-45 WPM. Selectable keyer configurations include:
  • Mode A or B keying
  • Adjustable weighting

  • Side tone ON/OFF
  • Right or left handed paddle

The VK-64 is compatible with the major contest logging programs, including N1MM Logger, NA, WriteLog, TRLog , CT and LogEQF.

Installing the VK-64 is easy! Unplug the microphone and plug the VK-64's transmitter audio/PTT cable into your radio. Plug the microphone into the VK-64's microphone input cable.
