This could have been done by tying into the web server portion of OpenWRT on the linux side the Yun and talking across to the ATmega programming. I was originally looking at using the Arduino Yun for the CW keyer project which could also allow remote control via the “Bridge” over a web browser. There has been a major change in CW keyer project that I was originally looking into, using this software, which I need to explain. USB Keyboard HID (Human Interface Device) Interface (Keyer = keyboard for your computer) (NEW). Modular code design allowing selection of features and easy code modification.Command mode for using the paddle to change settings, program memories, etc.Sidetone disable / sidetone high/low output for keying outboard audio oscillator.Hellschreiber mode (keyboard sending, memory macro, beacon).Speed potentiometer (optional – speed also adjustable with commands).CW keyboard (via a terminal server program like Putty or the Arduino Serial program).Optional LCD Display – Classic 4 bit mode, Adafruit I2C RGB display or YourDuino I2C LCD Display.Optional PTT outputs with configurable lead, tail, and hang times.Logging and Contest Program Interfacing via K1EL Winkey 1.0 and 2.0 interface protocol emulation.USB or PS2 Keyboard Interface for CW keyboard operation without a computer.Programming and interfacing via USB port (“command line interface”).Up to six selectable transmitter keying lines.There should not be any special configuration required to make the Mega work with this firmware. From what Anthony told me, all I need to do is uncomment the FEATURE_ lines that I want and recompile to the Arduino Mega. This gives a list of available features and options that you can add or remove from the firmware depending on your needs and or space available. The features, which are available through the king_keyer application firmware, are located within the file called keyer_features_and_options.h. Below will show what I am doing and what I am using to make this project work with my hardware. This is an awesome thing to play with and well worth it once complete. According to his web site, located at here are the capabilities that are in place at this time. To help myself learn CW and jump in with both feet, I am going to be building a copy of the K3NG CW keyer which has a lot of capability to work with. If it wasn’t for the software, this may have never gotten done. □ -=-=-=-įirst off, I want to thank Anthony (K3NG) for the hard work in the software for this project. Now, off of my soapbox and on to the project at hand. Lately, the sun has been very upset and the radio conditions on HF have been less than perfect. It challenges your mind and hand coordination and will always remain as a reliable means of communicating with other hams and even during emergencies, with other agencies on HF. Since the requirement to pass the CW portion of the test was removed by the ARRL years ago, which I feel should not have happened, it made it easier for more and more people to get into the hobby. Because I have lost some of the characters, I need to practice to get proficient again. I find myself send in my head occasionally, lol… I do feel bad for not pursuing the CW part of the hobby because I have missed out on some nice contacts and contests. You need to keep using it in order to stay proficient but you don’t really lose it all. This was not due to lack of interest, from what I can tell, but lack of time. I passed the test 1st time out because of the work that he put in.Įver since I got licensed after passing the 5 words per minutes code requirement, I did not touch it again. A local ham who is SK now bent over backwards to help me learn morse code by sending to me over the air and allowing me to use tapes that he had to practice copying. I was always told it is better to try and practice at 13 word per minute as you can pick it up better with the right spacing but I never made it that far. To upgrade to General, you had to learn 13 words per minute and to upgrade to the Extra Class, you had to learn 20 words per minute. In order to get my first license (Technician Plus) with HF privileges, I had to learn morse code at a level of 5 words per minute.
