Practice sending International Morse code with straight lever and iambic paddle CW Morse code practice oscillators app for Android smartphones and tablets. This app DOES NOT interface with your ham radio to provide a keying device.

Each practice oscillator translates International Morse code into Latin letters, Arabic numerals, punctuation, CW prosigns, and characters á, ch, é, ñ, ö, and ü in real time as you practice.

Practice sending Morse code with a straight lever oscillator. Settings include WPM, show/hide Morse code/text, choose sidetone 400Hz-800Hz. Adjust the WPM so that you can produce well formed DITs and DAHs at a comfortable speed.

Practice sending Morse code with an iambic paddle oscillator. Simply touch down on the DIT and DAH paddles instead of pinching, squeezing, or flinging the paddles. Settings include WPM, CW weight ratio, reverse paddles, show/hide Morse code/text, choose sidetone 400Hz-800Hz. Touch and hold both paddles to cycle between DIT and DAH and feel the iambic rhythm.

Here is a brief instruction on using an iambic paddle key to send Morse code:

Press and hold the Clear Code/Text button to adjust CW and Text label font sizes.

You may use a real straight key or iambic keyer with this app by connecting it to your Android device via an easily modified USB mouse.
