K1EL Keyers

K1EL keyers are well known and are pretty much universally accepted interfaces for most amateur radio software programs. If you are keyboading CW or running CW scripts from your computer, you need to use this interface. The reason is how the computer allocates processing time. From the K1EL website Windows is a multi-tasking operating system which means that the CPU is shared between many different tasks. This makes it very difficult to accurately time CW due to constant task switching. This results in unevenly timed dits and dahs. For example, in the middle of a word you might have an R with a really long dah in the middle or an A that sounds more like an M. By off loading CW generation to a separate dedicated microcontroller, all the timing problems disappear. Logging programs running on the PC send ASCII letters to Winkeyer for conversion to Morse, this allows the PC to focus on more important things.

I have both the WK Mini and the WinKeyer USB. The biggest difference is the Mini has to have a computer connected to it and the WinKeyer USB can operate stand-alone because it has buttons. Both are USB powered. The WinKeyer USB can run on batteries. I have a USB power port that I hook-up to the radio battery. It can also charge my phone.

How does it play? When hooked up to your computer, both can be controlled by software. ACLog by N3FJP has an excellent interface. Here is a screenshot of my setup on my Surface Go2.

As you can see, you can create CW scripts right in ACLog that will play through the WinKeyer. The scripts correspond with the F-buttons at the top of your keyboard. Or you can have a mini F button window within ACLog which you can click with a mouse or if you have a touch screen a touch of your finger. The latter is my preferred method. One of the benefits of controlling your WinKeyer with ACLog is you can pull data out of ACLog to use in the script. Notice in the F2 script, there is a $ and an *. The $ sign pulls the call sign in the Call window of ACLog and the * pulls the RST from the Sent window. Theoretically, you can make exchanges without even touching a paddle as long as everyone is using the same format.

The WinKeyer USB also works well in stand a lone mode (not hooked up to a computer). It can store up to 12 messages in two banks. There are plenty of ways to customize the messages. I will give a few hints but the instructions that come with the keyer are extensive. With the WinKeyer USB you can use the messages in ACLog and Winkeyer USB interchangeably. However, you must use the F buttons to trigger an ACLog message and the WinKeyer USB buttons to trigger a Winkeyer message

The first thing you do is plug the keyer into your radio and set the radio keyer to STRAIGHT key. The keyer will handle the rest. You plug your paddle into the keyer. Besides sending CW with your paddles, you can edit and change the messages and parameters of the keyer. There is also an app for your computer to interface with the keyer. It looks like this.

What is nice about Winkeyer USB is you can type in the message and not have to send CW via the paddle to create the message. It gives you more control over how the message is set up. Looking at message 1, it is a standard CQ message. However, I want it to repeat until I stop it (send a dit or dah with the paddles to stop it). Winkeyer was a beacon mode however it beacons at a set period of time. For example at 20 wpm I set my CQ to repeat every 13 seconds giving about a 3 second space between call. During my activation I slowed my wpm down to 16 and now I had no gap between CQ’s. The solution was to use the wait command and then the go to message 1 command. The wait command is the /W03 it means wait 3 seconds before continuing. the /1 means play message one. So now no matter what speed I set the keyer, I will always have a 3 second gap.

Next is the /R command. What this does is it treats the next 2 letters as a prosign like SK, KN, or BT. For POTA, I like to send BK as a prosign so the command is /R BK.

The last command you see is /Z3. What this does is slow the rest of the message down 3 wpm (you can change the amount). When doing a Park to Park (P2P) sometimes the park number catches you off guard. Your brain is thinking something else. So by slowing down the park number is gives an operator a chance to catch up and get the number.

When using radios like the Xeigu G90 which does not have CW memories or the Lab599 TX-500 which only has two. The Winkeyer gives you options to help make operating more comfortable. Let the keyer call CQ while you take a sip of coffee or let it say thank you while you are finishing up logging the contact. With the WinKeyer USB, you can keep the message buttons close at hand. The WK mini weighs in at 1.5 oz and the WinKeyer USB weighs 7 oz. Both are small and easy to toss into a pack. For more information: https://hamcrafters2.com/index.html


Larry Naumann N0SA builds keys and paddles as a hobby. He recently released a new design in a small quantity and I was lucky enough to get one. Larry is a CW guy and also likes to build paddles and keys. His new one is called the SOTA paddle and is designed for POTA/SOTA.

As you can see, it is a rather small paddle weighing 2 oz. including the cable. This is an amazing paddle with exceptional fit and finish. All corners are rounded and all edges deburred. The metal appears to be passivated which should provide a long lasting, corrosion resistant finish. Paddle tension is magnetic and Larry uses good sized magnets. You can tell they are there. The action is on par with other more expensive paddles. The action can be adjusted with the included hex key which is held in place by one of the tension magnets. I recently did an activation with this paddle along with my Lab599 TX-500. It was a cold dreary, drizzly day and both the radio and paddle did just fine. When I got home, all I did was blow dry the paddles with some canned air. You can see the YouTube video here:

The paddles can be attached to something using 4, 4-40 tapped holes (two on the top and two on the bottom) or it can be held in the hand. Because of my somewhat large, meaty hands, when I use the paddles as held in my left hand, I sent the occasional stray dah.

After my last activation, I removed the paddle from the flight deck and then had to do something with the knurled 4-40 screw I used to secure the paddle to the flight deck. I moved the screw from the bottom of the paddle to one of the holes in the top and put the paddles back in the bag.

A couple of days later, I pulled the paddles out to play with them. Yeah , I know, they do kind of grow on you. I made a few contacts from home, and I noticed that there were not any stay dahs! I looked at the paddle in my hands; the screw changed the geometry of how I held the paddle. The screw was pushing my fat index finger away from the dah paddle. Problem solved.

These are great paddles and fun to use. I enjoy using them both at home and in the field. Will they replace my Begali Simplex on the desk? Probably not, but if Larry decides to make a desk set of paddles… I don’t know when or if Larry is going to make another batch, but if he does, don’t hesitate, because they go fast.
