U Swap Users WK3 provides two complete user configurations each with a unique callsign Both message banks are available to both users This allows a universal set of messages to be created that will work with either user For example a message like CQ CQ CQ DE M M K will send the selected user s callsign In response to this command a single dit is echoed when user 1 is selected and two dits when user 2 is selected V Voltage Readout WK3 will measure the current supply voltage and send it in Morse sidetone For example a voltage of 4 52 will be sent as 4r52 with the r indicating the decimal point X Toggle paddle swap Exchange dit dah inputs WK3 will respond with a letter A to signify when paddle swap is enabled and an N when turned off Standalone Message Functionality Messages are loaded by pressing the command button until WK3 responds with an and then pressing the message pushbutton of the memory slot you wish to enter When WK3 is ready to accept a new message it will respond with an E If you wait too long WK3 will respond with a and you have to start over In some keyers such as WKUSB only four pushbuttons are provided messages 5 and 6 are accessed by pressing two pushbuttons in the following sequence after the R is echoed Press and hold either message button 2 or 3 this specifies message 5 or 6 respectively Press the command pushbutton Release both push buttons Message 5 and 6 can be played in a similar
4. A pseudo random letter generator is used to generate the sequence of letters Normally the seed for the generator is a random number but sometimes it is useful to generate the same sequence over and over during training sessions Use the P command with an S to set a fixed seed The format for the command then is P S d where d is a seed value between 1 and 99 A seed value of 0 will return to fully random operation Q Query WK3 Current Settings WK3 will respond with current settings sent in the following format WPM is sent first followed by Serial Number followed by free msg memory space in letters available followed by command WPM followed by weight followed by lead time followed by tail time followed by 1 extension this parameter described in host mode section followed by key compensation followed by Farnsworth WPM followed by Letterspace adjustment followed by Paddle Sample Adjust followed by dit dah ratio followed by speed pot min WPM followed by speed pot max WPM followed by firmware revision major minor 30 01 for 3 0 version 3 1 etc uUx mxmHrxozgz pb Review a message without transmitting After the R command is entered WK3 will respond with an E Press the message button of the message you wish to play The message will be sent in sidetone only If you try to play an empty slot WK3 will respond with MT Embedded commands will be sent as is without expansion In other words S10TEST will be sent as

Usually this is a 1 4 inch phone plug A two wire cable is all that is required to key a typical transceiver Plug the RCA side into either KEY1 or KEY2 and the other side directly into your transceiver s key input jack Make sure you disable the internal keyer in your rig if it has one and set it up for straight key mode If you are trying to key a vintage vacuum tube based transmitter WKUSB SMT will work fine because it employs solid state relays rated for 300V switching at 100ma This covers grid block keying but it may not be suitable for cathode keying If you decide to use keying paddles with WKUSB they plug into the paddle jack input on the back of the unit A 1 8 inch stereo jack is used on WKUSB for space reasons so if your paddles have a 14 inch size plug an adapter cable will be necessary You can use WKTEST to make sure that WKUSB is keying your rig properly If you run into problems make sure you have selected the correct key output port This is done in Output Config area of WKTEST the dialog box 95 of all installations will use the KEY outputs only The PTT outputs are intended for installations that require control of antenna relays or linear amplifiers PTT is asserted before KEY and is held asserted for the entire transmit interval The delays are adjustable look at lead in and tail delays settings WKUSB s RCA connectors are electrically isolated from the WKUSB enclosure and ground This means that you can directly con

WK and you should now see the new version number displayed FAQ 1 What is Standalone Mode and How is it different than Host Mode The original WinKeyer1 was designed to operate only while connected to a PC under control of a PC based application this is Host Mode WinKeyer obtained power directly from the PC over unused RS232 control lines if it was disconnected from a PC it was inoperative Soon hams started putting batteries in WinKeyers and using them standalone in other words not connected to a PC This spawned many requests to add features to make a standalone WK more useful When WKUSB was designed we decided to include a complete second keyer in the box and Standalone Mode was born This second keyer shares the core K1EL Keyer Engine with Host Mode but in All other respects it is independent It can operate on battery power or connected to a PC It has its own settings memory and 12 message slots Commands can be issued via paddle commands or through the use of WK3tools Standalone settings do not influence Host Mode settings In Host Mode keyer settings are stored on the PC by the application and are loaded when you connect to WKUSB In Standalone Mode the settings reside in EEPROM inside WKUSB If you disconnect from an application WKUSB will automatically go into Standalone mode and load saved settings from EEPROM FAQ 2 Are the internal batteries required if always connected to a PC When WKUSB is plugged into a PC power i

WKUSB3 QUICK START GUIDE September 17 2013 Revision 1 0 Thank you for purchasing a WKUSB SMT kit from K1EL The first thing to do is to assemble your WKUSB kit The assembly instructions are in WKUSB SMT assy pdf The assembly document will guide you through final assembly and check out of your WKUSB SMT Please read it all the way through BEFORE you start WKUSB operates in two modes standalone and host mode The assembly guide will instruct you how to do basic checks in standalone mode to make sure it is working properly Once that is complete the next step is to check out WKUSB SMT in host mode connected to a PC A word about USB drivers WKUSB SMT uses a USB interface IC manufactured by FTDI This is one of the most popular USB devices in existence We depend on their expertise with USB and they do a good job of maintaining reliable USB drivers that run on a PC and interface to their controllers Most WIN7 and WIN8 computers now ship with the FTDI USB driver preinstalled so you can just plug in WKUSB SMT and you are good to go Older WIN XP computers may not have a FTDI driver installed so it s a good idea to preinstall the driver before plugging WKUSB in Refer to the file ReadMeFirst wk3 pdf file for further instructions Once the USB driver is installed and you have plugged WKUSB into your PC refer to Appendix A in this document and determine which com port your WKUSB is assigned to You will need this piece of information to con
