The ETM-9C is an electronic memory keyer with built-in paddles. This kind of morse keying is not so straight forward but still rather easy to learn. Far more difficult than giving a text in morse code is decoding it while listening. The ETM-9C is good for giving text in high speeds. But remember, if you give a text in high speed, your QSO mate will think that you can decode in the same speed, and that's a hard skill!! Currently I'm a little out of practice, but generally I can handle speeds of about 90 chars per second.
Yes, I own two ETM9Cs. One for my lab and one for mobile operation.
