Amateur Ham Radio Straight Key

Practice sending CW Morse code with a software straight key oscillator. This app also translates the Morse code you send. Settings include set WPM, show/hide Morse code/text, choose side tone 400Hz-800Hz. Adjust the WPM so that you can produce well formed DITs and DAHs at a comfortable speed.
Please see my other apps and games including an iambic key practice oscillator and a 20 WPM Koch Morse code trainer here on Google Play.

Just a summary page to remember codes and this app is perfect 👌 I like your last update. Thanks for the interactive Chart (see the alphabet while I can play Morse at the same time) Nice 💡 idea!

In testing, key locked into a single continuous tone that would NOT stop until I powered my phone down!?! Back to the drawing board?

Wish I could give it more than *****(5) stars. Pulled it out on a few occasions to demonstrate Morse code. Nice tone and feed back showing characters correctly sent. 73
