MFJ-419 CW ELMER


What is it?  MFJ-419 is a multi-function training tool for learning to receive and send Morse Code with a straight key.  It helps you learn CW and send clean CW all in one little pocket-sized MFJ box. Carry it with you to work and time at the kitchen table!

How does it work?  Send mode operates like a Code Practice Oscillator allowing you to practice sending.  MFJ-419  will display the characters in code and in English. The Analyze setting will display your speed and timing to help you to send better.

Receive mode will help you learn characters. It can send in normal spacing or two Farnsworth speed modes sending the characters faster but spacing to the programmed speed. There is also a USB text mode where you can use a terminal program to send text either from a keyboard or a short text file to the MFJ-419 so you can listen to real text.

There is also an Exercise mode that will help you with training to make correct length dits and dahs and also the proper spacing between characters and words.

How does it set up?  It's easy!  There's a setting menu that allows you to alter WPM: 5-40, Timing: Normal/default, Farnsworth 18, Farnsworth 25, Character: Alpha only (default), Alpha and Numbers, or Alpha, Numbers and Punctuation, Sidetone: 200 Hz, 400 Hz, 600 Hz (default), 800 Hz and 1000 Hz.

How is it powered?  Use one 9 Volt alkaline battery or USB cable.

Are firmware updates available?  Yes. Firmware updates will be made available from the MFJ website or from https://www.arduino.cc/en/software. Current software will be greater than 1.8.16.
