This Android app gives you both International and Wabun Japanese Morse code
straight and iambic paddle practice key oscillators.
Each key translates Morse code into English with CW prosigns and
Japanese kana characters in real time as you practice.
You may select either English or Japanese language,
separate from entering Wabun Mode or International Mode.
Practice sending International and Japanese Wabun 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 International and Japanese Wabun 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 to send Morse code
With either practice oscillator, send Holl -..--- to enter Wabun mode, and send Lata ...-. to exit Wabun mode.
Remember, English or Japanese language setting and Wabun Mode are set independently.
You can set the language to Japanese, but still be in International Mode.
Likewise, you can set the language to English and also be in Wabun Mode.
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 repurposed USB mouse.
This Android app may be of interest to Japanese amateur ham radio QRP and QRO operators
and Wabun CW or telegraph enthusiasts.
