On the run up to Field Day I had some experience with N1MM, Fred ( AB1OC) added a WinKeyer and loaded his macros, and I had CW Skimmer already installed on the laptop. My ability to copy is improving but very limited. #Raspberry pi cw decoder licenseHaving my license for only 8 months with over 1000 SSB QSOs and zero CW contacts in the log I wasn’t a CW op but the station was available and the field day clock was running. I’m in the process of converting this documentation to a wiki on GitHub which will be much easier to navigate.Ira ( KC1EMJ) and I helped set up the IC-7300 80, 15, and 10m CW station. If you search for “USB Keyboard” on the project page ( ) you’ll find the USB keyboard feature instructions. I think a lot of folks use the Nanokeyer mainly for K1EL Winkey emulation and interfacing with contest and logging programs. I’ve mention to DJ0MY, with whom I’m good friends, that an Arduino Mega CW keyer shield might be a good project considering how limited the Nano is. With the Mega or Due boards you can compile and upload the whole nine yards and get all the features in one package with the appropriate circuitry. #Raspberry pi cw decoder codeThe Nano can basically support code for the memories, K1EL Winkey emulation OR PS2 Keyboard. #Raspberry pi cw decoder softwareA USB HID port can be emulated in software on an Arduino using the native USB port, however it requires a good deal of code, more than the Nano can handle. It would be rather difficult to physically include a USB host port and the chips required to support it on a package the size of a Nano. Keep in mind the Nano’s claim to fame is small size, not features or horsepower. Are there any features you would like to see in a keyer that the current crop of keyers doesn’t have? I’m sure that I’ll think up some other features as well. For example, I can see experimenting with an LCD display to give me a readout of speed the keyer is set to, and there’s some experimental code to decode CW as well. :)Īll things considered, for less than $50, I have a keyer that I can not only use just like my other keyers, but one that I can experiment with as well. phone plugs because that’s what the WinKeyers use. phone plug on the back for connecting paddles, and I just converted all of my paddles to 1/8-in. I e-mailed DJ0MY about this, and he said that he didn’t think that Arduino Nano would support this mode. When I tried to compile the software with that feature, I got a bunch of compile errors. Unfortunately, the USB keyboard feature doesn’t seem to be working.I played around with it using the N1MM software, and it seemed to work without a hitch. They’re so bright that they can be a bit distracting. There are three LEDs: a green LED for power, a red LED that shows the PTT output, and a blue LED that shows the keying output. I’ve been using the keyer for a couple of days now and like it a lot. #Raspberry pi cw decoder installFortunately, with some careful soldering, I was able to install the header properly.Īfter downloading Oscar’s software package, I successfully compiled and uploaded the Arduino program, and I was on the air. In doing so, despite an explicit warning in the assembly manual, I managed to cut of an extra pin. Oscar sends you 20-pin headers, but the Arduino Nano has only two rows of 15 pins, so you have to cut down the 20-pin headers into two 15-pin headers. One of the difficulties I had was that I managed to mangle one of the headers that the Arduino Nano plugs into. Aside from a few little gotchas, I managed to get it all together in a couple of hours. I purchased the kit, it arrived within a week, and I built the kit that evening. You then download a version of the K3NG software, and you have yourself an Arduino-based keyer. For $35, Oscar will send you a kit of parts that allows you to build a board, into which an Arduino Nano plugs. Then, I stumbled upon the NanoKeyer kit by Oscar, DJ0MY. More recently, Goody, K3NG has been developing a more complete Arduino keyer software package. Way back in 2009, the September/October issue of QEX featured an article by KC4IFB on building an iambic keyer with an Arduino. #Raspberry pi cw decoder how toAt Dayton, I had so much fun giving out my CW Geek buttons that I started to think about how to extend the CW Geek “franchise.” One of the first thoughts that came to mind was designing and building a CW Geek keyer.Īs I attended a couple of talks about using the Arduino open-source microcontroller platform in amateur radio projects, I decided to Google around to see what might already be available.
