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
  • Adjustable side tone frequency
  • Side tone ON/OFF
  • Right or left handed paddle
  • Tune function

The VK-64 also includes a built in LPT CW interface. Most contest logging programs support sending CW through the printer port. Computer keying works in parallel with the internal CW keyer.

Message 1 for both CW and voice modes can be set up for auto repeat. The delay time can be adjusted from approximately 1/2 to 12 seconds with a front panel control.

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. The VK-64 automatically switches the microphone for recording and play back. The rest of the time your microphone audio and PTT signals pass through the VK-64 and connect directly to the transmitter, even when the VK64 is powered off.

CW set up is as simple as plugging your paddle into the VK-64. CW out connects to the CW jack of your transceiver. Adding computer control only needs a standard 25 pin shielded computer cable between the laptop or PC and the VK-64.

Cables are not included, but can be easily made according to directions in the manual or purchased from Unified Microsystems.

A 12V wall transformer is included with the VK-64.
