Remote Keyer

May 20th, 2021

This keyer is designed to work with paddles to key a local transmitter directly, or, send the characters out of the USB port to use with remote systems such as and If you are one of those hams that can send Morse at 40wpm but hunts and pecks on the keyboard, consider that you can use this to type emails or any kind of text just like you were using a keyboard, but using your paddles!!

Since I started operating remotely from time to time, using, I’ve wanted to be able to use paddles to operate CW. I love the system, it uses NO ports on the router, and the uptime has always been 100% from what I can tell. Marcus has done a great job and it keeps getting better.

So, Marcus and I have been playing with a certain Arduino that actually can output out the USB port and act like a keyboard when you send CW! So, I designed a board and he changed the K3NG Keyer software to include a tuning knob and a PTT for his remote system.

The boards came out clean and fully functional. To keep the costs down I designed a 3D printed box for it. Not as fancy as a nice metal box but operational. I’m looking at some upgrades for my drill press so I can drill holes with some kind of class and have them come out straight. Once I do that there will be two versions.

The board was designed to slide into a very common 80x100mm box.

So, enjoy the videos of the development and I’ll include the other details, like the code, schematic, and manual here in the next few days.

I have these available for sale as complete units ready to plug and play. In the 3D printed box, they are $95 shipped. Since there is a limited number of them, I’d suggest checking with me on availability at The same address works for Paypal.
