Introduction
This document will describe the K1EL WinKeyer3 (WK3) IC and its' various interfaces. WK3 is a third
generation single chip Morse keyer IC. It is designed to attach to a PC's USB port and provide accurate
transmitter keying for Windows based logging or other ham radio software packages. Due to timing
latency inherent in the multi-threaded Windows operating system, it is difficult for a PC to generate
accurately timed Morse. WK3 buffers ASCII characters sent by a Windows based software application.
It then translates them to Morse and directly keys a transmitter or transceiver. In addition, WK3 has a
paddle input allowing an operator to break in and send directly at any time. WK3 also provides a speed
potentiometer interface so that an operator can instantly dial any speed desired.
The host PC communicates to WK3 over a simple serial interface which can be a COM or USB port.
Letters to send, along with operational commands, are sent from the host to WK3 over the serial link. A
substantial feature list is provided allowing the user to precisely tailor WK3's keying characteristics to a
particular transmitter. WK3 has a very low power requirement; in fact, it was originally designed to be
powered from a PC's serial port. In standby it draws under a micro amp.
K1EL and several other manufactures sell products that utilize the WK3 IC, refer to the k1el website:
www.k1el.com
for further information. One popular kit is Hamcrafters WKUSB which includes a USB
interface, speed control, enclosure with pushbuttons, and an internal battery pack for standalone use.

Due to timing latency inherent in the multi-threaded Windows operating system, it is difficult for a PC to generate accurately timed Morse.

Not all, but many of WK3’s immediate commands can be entered as buffered commands. WinKeyer3 IC Interface & Operation Manual 6/11/2017 Rev 1.2 Page 2...
- Page 3 Configuration changes issued while under host mode will be cancelled when returning to standalone mode. A simple Windows application is available from K1EL called WK3MGR which can be used to set the standalone configuration and message contents from the PC. Alternatively, settings and messages can be entered by paddle commands in standalone mode.
- Page 4 WKUSB can be used as soon as the PC wakes up and leaves standby mode. Firmware Update The firmware image within WK3 can be upgraded in the field. When K1EL releases a firmware update, it can be uploaded to the WK3 IC through the WK3MGR utility over USB. Updates will be available from www.k1el.com/wkupdates.html...
