- Page 3 AF in tune output mode. WKUSB-AF only has three message pushbuttons but by pressing two of them you can send five messages. Lastly, WKUSB-AF is like WKmini in that it only has one output jack which provides two individual key output ports or one key output port with PTT.
- Page 4 Don’t plug WKUSB-AF into your PC until you have read this paragraph !! WKUSB-AF C uses a CH340 USB interface IC which is very reliable and easy to set up. Windows drivers for this device can be found on the WKUSB-AF website. There are two versions; a self installing .exe and a zip file containing the individual drivers as used by Windows Update.
- Page 5 Key2/PTT1. It can be setup as a single keyed output with an optional PTT or as two individual Key1 and Key2 outputs. The outputs are isolated from WKUSB-AF ground and other signals by an optically coupled, solid state relay which insures a 5000V isolation barrier. The outputs can switch up to +/- 350 V, at a current up to 120 mA.
- Page 6 You can click on ? shown in the upper right corner of the dialog box for a brief help menu. Click on Open to connect to WKUSB-AF. If all is well, the Open pushbutton will change to Close and the WK IC version will be displayed.

- Page 8 When a WinKeyer device is not controlled by a host application, it will run in standalone mode. WKUSB-AF can be powered over the USB port or by a set of internal batteries. WKUSB-AF in standalone provides a complete Morse keyer with lots of capabilities. Originally, configuration changes could only be made using commands entered on the paddles.
- Page 9 A tally of available message storage left is shown below the message text windows. Even though the WKUSB-AF has only three message pushbuttons, it has the capability to handle 12 messages in two banks. Messages 4 and 5, in each bank, are accessed by pressing two buttons (see page 54).
- Page 10 K1EL WKUSB-AF WKUSB-AF User Manual Once you have saved messages and settings, they are ready for use. You can now disconnect WK from the PC. You don’t need to use WK3tools again until you want to make changes. Don’t forget you can still make quick changes to WK settings by using paddle commands, no PC required.
- Page 11 WKUSB-AF User Manual RF Immunity There are several RF filters included in the WKUSB-AF circuit design. Bypass capacitors on the Key and PTT lines prevent RF from coming into WKUSB-AF. Bypass capacitors shunt any RF arriving over the paddle leads, and an LC filter is employed on the USB power input. These components also reduce WKUSB-AF RFI radiation.
- Page 12 WKUSB-AF FAQ #2: Does WKUSB-AF have internal batteries like WKUSB does ? No, WKUSB-AF is powered only from the USB I/F connector. It has to be plugged into a PC, a phone charger, or USB battery. Due to the extra power draw of the audio amplifier circuit, WKUSB-AF does not go into full low power sleep like WKUSB does when not active.
- Page 13 Connecting WKUSB-AF-SMT to your station Minimally all you need to do is connect the USB cable from WKUSB-AF to a USB port on your PC and connect the key output to the keying input on your rig. Since WKUSB-AF performs the keying function it drives your rig in the same manner as a straight key.
- Page 14 If you decide to use a set of keying paddles with WKUSB-AF, they plug into the paddle jack input on the rear of the unit. An 1/8 inch stereo jack is used on WKUSB-AF. If your paddles have a 1/4 inch size plug then a 1/8”...
- Page 15 Troubleshooting hints 1) When I plug WKUSB-AF into a USB charger I don’t get the initial R sent in sidetone. This means that that the WK3 IC is not starting up. Make sure the charger is working. If you are using a USB charging battery be aware that most of these have a minimum working current requirement.

Page 45: Ptt Lead And Tail Times
WKUSB-AF User Manual PTT Lead and Tail Times WKUSB-AF’s PTT output is used to control an accessory device in addition to normal CW transmitter keying. In most cases this device is a linear amplifier but it could be an antenna changeover relay or PTT input of a transmitter. -
Page 46: Paddle Mute
Autospace works in the following way: If you pause for more than one dit time between a dit or dah, WKUSB-AF will interpret this as a letter-space and will not send the next dit or dah until the full letter-space time has been met. The normal letter-space is 3 dit spaces. WKUSB-AF has a paddle event memory so that you can enter dits or dahs during the inter-letter space and WKUSB-AF will send them as they were entered. -

This would look like this, loaded into slot one: K1EL BCON /W12 /1 K1EL BCON will be sent followed by a 12 second delay after which there is a jump back to the beginning. The second way is to use the embedded beacon command, which is easier:... -
Page 57: Standalone Qrss/Hscw Operation
Finally, the third method is an ‘on the fly’ beacon. In this mode, any message slot can be sent as a beacon, for example if K1EL BCON is loaded into slot three, the user would press the command button, wait for the R, and then enter B 3 12. -
Page 58: Shortcuts And Speed Ups
When you are satisfied with the pitch, end the command by pressing the command PB. WKUSB-AF uses a small internal speaker and you’ll find that higher frequencies produce the loudest sidetone. CPO sidetone can be tested by connecting a set of stereo headphones or speaker with a stereo plug into WKUSB-AF’s audio output. - Page 59 If you need to insert / into a message simply enter it twice, this tells WK it is not a command: K1EL//1 Another set of speed related embedded commands are /Y and /Z.

Page 60: Wk Standalone Rtty Tutorial (Using Paddle Entry To Send Rtty)
Now let’s compose a beacon message. In message slot 2 enter: /B60/K05 BCON DE K1EL NH When this message is sent, the keyer will key down for 5 seconds and then send BCON DE K1EL NH. The /B60 command tells the keyer to repeat the message every 60 seconds no matter how long the message itself is. To cancel a beacon, press the CMD PB or the paddle. - Page 61 The recommendation is to use diddle to fill in the empty space between paddle input letters. Be sure that WKUSB-AF internal sidetone speaker is enabled (the A paddle command) so that you can monitor paddle dit/dah entry.
