iPhone as a CW Keyer or Code Practice Oscillator??
Is it possible to connect a paddle/key to my iPhone via the headphone or charger jack and then use an app as a keyer/code practice oscillator? Anyone try sending cw via Skype or similar program on your iPhone?
There are a few morse code programs that allow you to tap a virtual key and there's one that is a virtual iambic paddle. I have not see one that uses the microphone jack though.
