This is one of the best cw tutor apps available - Five Stars! Just what I needed for handy practice anywhere anytime! Highly recommended! - Five Stars! This is the best app I've found for increasing my code accuracy and helping to increase my speed. Five Stars! Ham Morse allows you to practice morse code on your iPhone, iPad or iPod Touch. It is designed particularly for Ham radio operators and others who wish to achieve or maintain a high level of proficiency in this classic mode of communication. Ham morse has the following features: The code is sent using the Farnsworth timing whereby the morse characters are sent at 15 words per minute (WPM) and then extra spacing is added to slow the overall WPM to speeds slower than 15 WPM. The farnsworth speed can be adjusted if you wish to use a speed other than 15WPM. The maximum speed that the morse can be sent at is 50 words per minute. The morse audio waveforms have a 5ms rise time to reduce key clicks and yet provide crisp code to copy. The audio frequency can be varied from 220Hz up to 900Hz. A typical value might be around 700Hz but a lower tone can be very useful in some situations. The code can be paused just in case you are interrupted or want to take a break, an incoming call on an iPhone pauses the code automatically. To help you learn the morse code itself HamMorse allows you to practice a variety of sets of characters from individual random letters all the way to the current news stories from around the world. Koch - This setting uses the Koch character progression. It starts with just one letter and then you can add a new letter when you have mastered the previous character set. This is one of the most popular methods of learning the morse character set. Letters - Practice the individual letters, A-Z. Add new letters to your practice set using the settings page. Numbers - Practice the numbers, 0-9. Which numbers you practice can be controlled on the settings page. Callsigns - allows you to practice receiving random amateur radio callsigns, a mixture of letters and numbers (eg AA9PW, G1SNT, G5RV) that often prove troublesome when copying code on the air. HamMorse creates a wide variety of international callsigns using the standard ITU prefixes to provide useful practice where ever in the world you may be. Punctuation - provides a wide variety of punctuation and standard morse code prosigns. Top 100 and 500 most common words - this is a great way to start to recognize whole words the key to really improving your speed. News feeds - these provide the opportunity to copy real sentences and keep up with the news at the same time. Note that the News feeds will only work with an active network connection. Ham QSOs - listen to examples of typical on-air exchanges between ham radio operators - practice coping the callsigns, RST reports, location, rig, antenna and many other pieces of a typical QSO. Accessibility support - The app also has support for Apple's accessibility tool, Voice Over. When Voice Over is activated each button and field has an audible description available describing the button or slider and its use. Text Delay - As an additional learning aid You can have the text appear a few seconds after the morse code is played so you have time to copy the letter before it appears on screen. Text Filter - Filter out characters from the News feeds or QSOs that you are not yet familiar with so you can start practicing with real text even if you don't yet know the whole morse character set.
