 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

This is probably a bit specialized for many users. As an amateur radio operator (K2WML), I am always trying to improve my Morse Code reading ability. I wrote this little app to help. It features several different Morse Code reading practice methods: 1. Random text selections from a long file of random text gobbledygook. 2. Random alphabetic characters. 3. Random alphabetic and numeric characters. 4. Random alphabetic, numeric, and punctuation characters. 5. Koch Incremental Learning System characters. You can set the code speed, beep frequency, and the number of characters in a practice session. The program will remember your choices and present them the next time you use it. The Koch Incremental Learning system is the most effective way of learning Morse at realistic speeds. Give it a try! The program includes built-in help. Enjoy! -Bill Morse.zip |

Thanks. When I was studying for my Amateur license, I wrote a Morse Code practice program for my ZX81 It was very limited but did the job. This was something on the long to-do list< along with a RTTY terminal. Jim VK7JH MMedit |

The only way to improve speed and accuracy reading either international Morse or the older Morse landline code is to listen to a lot of it. I had a great uncle, John Uzarowicz, who signed on as an AT&T engineer about 1897. (The name American Telephone and Telegraph was derived from the use of the high side of two separate voice pairs to transmit Morse code with DC levels thus enabling two voice circuits plus one code circuit over four wires.) These early engineers would sit around in a long lines switching center with a dozen clackers clipped to various lines leading all over the country and listen to multiple simultaneous chats with other engineers and understand them all. Try as I might I could never read landline Morse received with a clacker. At PanAm we had two guys who had served as ships radio officers during WWII, Bob Ackerly and Norbert Kukala. On ocean going ships they used 150 Watt CW finals driving a long line antenna stretched from the bow to the stern of the ship. The calling frequency was 500 KHz. They considered it routine to work Press wireless (transmitters in Hicksville NY, receivers in Litle Neck NY, call signs WJO, WJP, WJQ, WJS, & WJU) from the South China Sea reliably at 25 wpm. I had an Amateur Extra license (my first call in the 1950s was K2JLN) which meant I could sometimes read 18 wpm and maybe send 20 wpm, but Norbert and Bob could blast out letter perfect code at 25 wpm using straight keys, not Vibroplex bugs. Their fists sounded like machines. They had built 555 practice oscillators and would have QSOs from opposite ends of a 40 foot room packed with engineers and would squawk loudly about all of the QRM and QRN (See ham abbreviations here.) emanating from all the guys talking in the room. They said that if they didn't QSO every day their speed would decrease. Paul in NY (Older than dirt!) Edited 2020-11-04 19:50 by Paul_L |

How'd you manage the lack of sound on the ZX81 - or did you do something clever with RF interference (IIRC -- it was 40 years ago....) N Entropy is not what it used to be |

I forget the details but I was limited to one speed and had to save it to tape for later playback. I would make a few tapes and listen to them on night shift much to the annoyance of my colleagues. Jim VK7JH MMedit |
