Super Morse is the original comprehensive Morse Code training program for the PC. Super Morse permits the user to learn the Morse characters in a very orderly way using several different methods, including one unique to Super Morse; build speed with special exercises

RufzXP is an excellent free training software for improving code speed and CW practice, particularly (ultra) high speed memory copying of true amateur radio calls.

Mose Trainer by G4FON is a free windows morse code training program developed using the Koch method. Sends words simulating real morse code transmission, with QSB and QRM, allow change speed tone and many other settings. Download the kochmorsetrainer_install file and start learning Morse Code.

Simulates a **CW** contest environment, presenting operators with realistic scenarios for improving their receiving and sending proficiency under pressure. The software generates varying signal-to-noise ratios, QRM, and QRN, replicating conditions encountered during actual **DX** contests. Users practice copying callsigns, exchange information, and manage pileups, with customizable parameters for speed and difficulty. The program provides immediate feedback on accuracy and speed, allowing for targeted skill development in a controlled setting. It supports various Windows operating systems, from Windows 95 through Windows 10, and can also run on macOS using Wine.

Popular, versatile and easy to use Morse code training software written with the latest PC software technologies, and it is free with support. Guaranteed to increase your speed!

Over 130 years after its inception, Morse Code remains a fundamental skill for many amateur radio operators, enabling efficient QRP operations, DXing, and contesting. This resource provides an in-depth look at the **Koch Method** of Morse training, a widely adopted technique that emphasizes high-speed character recognition from the outset. It details how this method can significantly accelerate proficiency, moving beyond traditional, slower learning approaches. The site also delves into the rich history of amateur radio, presenting articles such as "Radio on the Rio," which chronicles local ham activity in Socorro, New Mexico. Another piece, "The Russian Woodpecker," recounts the Cold War-era efforts of hams to counter Soviet over-the-horizon radar interference on the HF bands. Furthermore, the resource explores the fascinating intersection of ham radio and radio astronomy, highlighting the direct lineage between amateur experimentation and the development of modern radio telescopes like the **Very Large Array (VLA)**. It also includes an introduction to the 6-meter band, often called "The Magic Band," detailing its unique propagation characteristics and suitability for no-code licensees seeking long-distance contacts.

The free CW Speed Training Software for Windows by JI0VWL

The **Nilex Morse Tutor** is an HTML5 web application designed to teach Morse code reception, adapting to user proficiency by adding new characters as readiness is detected. It prioritizes practice on less familiar letters, numbers, symbols, words, and phrases, while minimizing repetition of already mastered elements. The program offers multiple learning orders, including "Q7ZG..." (Ward/Jim's), "KMRS..." (PU5EPX/Koch), "KMUR..." (lcwo.net), "AENT..." (CWops CW Academy), "TEAN..." (Stephen C Phillips), "ANET..." (Vic VE3YT), and "ETI5..." (Ham Whisperer), alongside an alphabetical option. Users can customize the learning experience by enabling or disabling automatic progression, and selecting specific content categories such as numbers, symbols, words, phrases, QSO bits, Ham Radio Bands, X+Y=Z math, and units. Audio settings are adjustable for volume, speed (WPM), tone frequency, and keyshape/keying envelope, allowing for a personalized auditory environment. The interface provides visual feedback with blue bars indicating practice emphasis and gray bars for reserved characters, with clickable bars for manual character selection. Developed by "Nosey" Nick Waterman, VA3NNW, this tutor is based on earlier versions by Jim Wilson and a 1977 QST article. A significant October 2019 rewrite incorporated a new WebAudio sound library by AwesomeAidenW, improving offline functionality and mobile support. The content library was expanded to include 3000 top Google words, 2284+ General Service List words, ISO country codes, capital cities, US states, Canadian provinces, UK counties, common names, periodic table elements, quotes, Q-codes, electronic components, ham abbreviations, and example call signs. The software is distributed under the GNU GPL V2 license.

Morse Walker is a web-based tool for amateur radio operators to practice CW skills. Inspired by Morse Runner by VE3NEA, it simulates pileup scenarios and contest formats like POTA, CWT, and SST. Modes include single-caller exchanges and basic contests, offering realistic experiences to improve speed, accuracy, and QSO handling. Ideal for contest preparation or honing activation skills, Morse Walker helps operators enhance proficiency in CW communication. Start your training today at MorseWalker.com

The recognition of telegraphy masked by noise at 40 and 80 signs/min telegraphy speed was studied in 10 normal-hearing subjects at different sound pressure levels (25-85 dB SPL in steps of 5 dB) as well as at different test frequencies (2000, 1000, 800, 630, 500 and 250 Hz). The ability to recognize the signs varied with varying SPL. Recognition for most of the subjects was best at an SPL close to 70 dB. All subjects improved their recognition as the frequency was lowered to 500 Hz, some even at 250 Hz. These facts should be taken into consideration when training telegraphy operators as well as in the construction of radio receivers to permit listening at low frequencies. Furthermore, the critical ratio was calculated at the different test frequencies.
