This Android app gives you both straight and iambic CW Morse code practice key oscillators.
Each key translates Morse code into English and CW prosigns in real time as you practice.
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 auto key 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.
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 amateur ham radio QRP and QRO operators and CW or telegraph enthusiasts.
