This Amateur ham radio software app for Android devices allows you to practice sending Morse code with an iambic paddle practice oscillator. This Android app DOES NOT connect to your ham radio to provide a keying device.

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.

This iambic practice oscillator app 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.

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

This app may be of interest to amateur ham radio QRP and QRO operators and CW, Morse code or telegraph enthusiasts, and preppers.

Ratings and reviews

I really like the way this app allows me the option of not knowing what I'm keying until I key it. This gives me the opportunity to keep practicing a single character 'til I get it right. I knew exactly zero codes and, while it took me 10 minutes to learn it, I can now key my first name with ease (after using the pop up chart, a lot). Thanks for including that! I have a small 5 in. screen so I was happy to see the entire bottom 1/4 of it is devoted to the paddles. Video describes it to a "T"!

laggy. even more bothersome, that i let go of the keys and it keeps typing .-.-.-.-.-.- forever

Excellent good Morse code practice.
