![]() The MFJ-418 is an excellent trainer, but, like the other trainers, there’s no provision for teaching you how to send Morse code. After an hour or two, however, these limited inexpensive boards end up in my desk drawer. I own several of the inexpensive Chinese manufactured kits, and they’re fine for limited practice of random letter groups and call signs. There’s also no shortage of microcontroller-based trainers, starting at about $15 for poorly documented kits on eBay, to the excellent $95 MFJ-418 Pocket Tutor. These programs support the modern use of words and phrases transmitted at 20 or more words/minute, with adjustable space between letters and words. My go-to for iOS devices is Morse-it, which sells for about $5 by the time you purchase the key add-ons. My favorite browser-based program is or Learn Morse Code (CW) Online. Today, there are dozens of freely accessible websites and free or inexpensive apps for Android and iOS tablets and phones that provide sophisticated and efficient Morse code training. ![]() Fortunately, times have changed, and Morse code teaching techniques and the associated technologies have matured. I memorized that LP, focusing on individual letters at five words/minute.Īs a result, it took me years to learn to copy entire words and phrases in my head at up to 35 words/minute. I still remember the RadioShack Morse code course on 33LP that followed an antiquated approach to teaching, starting with “dit,” “dit dit,” “dit dit dit,” “dit dit dit dit,” “dit dit dit dit dit” (e, i, s, h, 5), and so on. Let’s face it, any grade school student with a cell phone can talk and text with anyone else on the planet with a similarly equipped smartphone.Ĭompared with simply speaking or even typing with both thumbs, learning Morse code can be a difficult time-consuming endeavor. I could review the technical superiority of Morse code (practiced as CW, or continuous wave) over other modes of communications, but the bottom line for me is that communicating with dits and dahs in a jumble of noise and other communications signals is just plain fun. If it is still not working, upload with pic and I'll help you troubleshoot further.Proficiency in sending and receiving Morse code - while no longer required for licensure - is the best way to experience traditional ham radio. Try checking the connections and code again. The first one is a circuit sketch, second one is a circuit diagram and the third one is an actual photograph. Also, I used a generic board from China, which didn't even have the manufacturer's name. The technical specs of both the Elegoo board and the Arduino board will be same, the only difference being it is manufactured by different companies. Using an Elegoo Uno R3 should be fine as Arduino is opens source. Also did you directly download and use the file 'Morse_code_decoder.ino' or did you type the code manually in your compiler. I will be able to help you better with that. ![]() If possible, upload a pic of the circuit. There must be some issue with either the circuit, the code or in worse case the board. When you press the reset button all I/Os are triggered so the LED must be lighting because of that. Static String letters = code = "" //reset code to blank string numberFound = false //reset to search for numbers again.
