    This Android app gives you both straight key and iambic paddle CW Morse code practice oscillators.
    Each oscillator translates International Morse code into Latin letters, Arabic numerals,
    punctuation and CW prosigns in real time as you practice.

    Characters translated:
    Latin letters A to Z, plus á, ch, é, ñ, ö, and ü
    Arabic numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
    Prosigns AA, AR, AS, BK, BT, CT, HH, KN, NJ, SK, SN, and SOS
    Punctuation , / ' ! : ; - _ " $ @ and stop

    Practice sending Morse code with a straight key 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.

    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 with this app by connecting it
    to your Android device via an easily modified USB mouse.

    This Android app may be of interest to amateur ham radio QRP and QRO operators and CW or telegraph enthusiasts.
